In the upcoming weeks, many aspiring paramedic students will be taking to the various ambulances and preceptors available to them. They will be thirsting for those big calls and knowledge to support them in their development; but it’s not always the big calls that make the student. Preceptors can have a big influence and impact on the student’s learning and development. A very important skill that the preceptor must posses is the ability to understand what the student’s needs are and implement methods to ensure those needs are met.
As a preceptor, you are:
An assessor: Assessment is a process of improvement, based on providing high quality feedback. This usually comes from only one person and depends very much on the context in which it is delivered. Improvement is measured relative to the previous performance, not a set standard of predetermined outcomes. The goal of an assessment is to improve performance.
A mentor: This helps the student learn and grow through clinical experience. The ultimate goal of mentorship is a self-actualized student who is able to direct his/her own development and growth.
An evaluator: You, in conjunction with the student’s college, will determine the students ability to perform in the field post-graduation.
The key to being an effective preceptor is to understand you need to fulfill all 3 roles and to choose the appropriate role at the appropriate time. Remember some of the keys to being an effective preceptor are to:
1. Be in the right role at the right time (right time is determined by the needs of the student).
2. Ensure the student understands what function you are fulfilling.
You are the greatest extension of the classroom and have the chance to have the biggest influence and positive impact in the learning experience.

Measure: 8 Ball
Describes 1/8th of an ounce of a hard drug or 3.5grams.
Measure: Ounce / Zip / Onion / O
Describes 1oz, or 28g of drug. Many low level drug dealers purchase street drugs by the ounce and sell by the gram.
Measure: 9 Pack
Describes 9oz of drug. Term is usually reserved to describe hard drugs such as crack, cocaine, meth and heroine. Lower to mid-level drug dealers generally purchase street drugs by the ‘9 pack’.
Measure: Backpack / Half-Plate / Half-Key
Describes 18oz of drug or 0.5kg. This reflects mid-level trafficking.
Measure: Key / Plate / Brick
Describes 1kg of hard drug. Generally speaking, hard drugs are sold by the kilogram, however marijuana is sold by the pound.
Posted on: January 16, 2018
Refers to meth. Meth can be sold as little as 1/10th of one gram at a time – which is the equivalent of one point. Therefore, one gram would equal 10 points. This is similar to Heroin which is also sold by ‘point’.
Measure: 20 piece OR 40 piece
Refers to crack. Many users are unable to afford to purchase crack by the gram. Instead they purchase a ‘20 piece’ or ‘40 piece’ which is equivalent to 0.2g or 0.4g at a usual cost of $20 or $40.
Most street drugs are purchased by gram (measured weight) or less. So for example, a person may buy a gram (1g) of crack or cocaine.
Measure: Half Ball
Describes approximately 1.7g of a hard drug such as crack or cocaine. The term half ball is refers to the actual weight of an ‘8 ball’.

Answer: Great question! There are actually a couple ways of doing so. Keep in mind that administering D10W to hypoglycemic patients is new to the majority of Paramedics in SWORBHP region; and that the appropriate dose is 0.2 g/kg (2 ml/kg) to a maximum of 10 g (100 ml).
It’s likely that the D10W on your trucks is supplied in a 250ml bag (or similar), which means that you have far too much medication available in that one bag and are required to measure out the appropriate volume in order to administer the appropriate dose.
So, how do you measure out the appropriate volume?
CASE: Your hypoglycemic pediatric patient weighs 40 kg – the required dose is 8g and required volume is 80 ml.
Option 1: Set up an Inline Volumetric Cylinder (ie. Buretrol) to the bag of D10W and fill the chamber with 80 ml of fluid. Once filled with 80 ml, clamp above the chamber and run the line below. The inline Volumetric Cylinder prevents larger volumes of fluid inadvertently being infused.
Option 2: Use a large syringe to draw up 80 ml of D10W directly from the bag and administer via IV push (much like you would push D50W).
Note: SWORBHP does not support simply attaching the bag of D10W to an IV line and measuring volume administration via bag markers. One of the above two options must be used.
When selecting your option for administration, use clinical judgment and decide based on ease of use, safety, available equipment and timely medication delivery. Ensure you go through the RIGHTS of medication administration and perform an independent double check with your partner. The most important step is safety – safety of the appropriate dose, route, method, etc.

We understand the potential for confusion! The excerpt below is found in the ALS PCS v4.3 within the Medical Cardiac Arrest Medical Directive.
“Consider very early transport after the 1st analysis (and defibrillation if indicated) in the following settings: pregnancy presumed to be ≥20 weeks gestation (fundus above umbilicus, ensure manualdisplacement of uterus to left), hypothermia, airway obstruction, suspected pulmonary embolus, medication overdose/toxicology, or other known reversible cause of arrest not addressed. Similarly, plan for extrication and transport for patients with refractory ventricular fibrillation and pediatric cardiac arrest (after 3 analyses), ensure quality CPR can be continued.”
- The 1st paragraph speaks to initiating transport after the 1st analysis in cases of known reversible cause.
- The 2nd paragraph speaks to initiating transport after 3 analyses for patients with refractory VF, in addition to pediatric patients in cardiac arrest.
So what does this actually mean? What are the intentions of these Clinical Considerations?
- The majority of pediatric cardiac arrests are a result of a reversible cause
- In most cases, transport following the first analysis since the majority of pediatric cardiac arrests are related to reversible causes
- If you do stay on scene for 3 analyses, be prepared to transport the pediatric cardiac arrest patient
- ACPs – You’re extremely unlikely to receive a field pronouncement
- PCPs – Pediatric patients don’t meet TOR criteria
- Rarely, a pediatric patient requires defibrillation
- In these cases, remain on scene for a maximum of 3 analyses to provide defibrillation
Ultimately, the medical directive allows for clinical judgment: It allows the paramedic to transport pediatric cardiac arrest patients after one analysis if presumed reversible causes of cardiac arrest exist (ex. sepsis, hypoxia) or otherwise stay on scene for 3 analyses (e.g. VF arrest).

Naloxone can reverse respiratory depression and apnea in opioid toxicity but it does NOT reverse cardiac arrest. Focus during cardiac arrest should be on effective CPR and ventilation in addition to defibrillation and epinephrine (ACPs). In rare circumstances such as with a high ETCO2 or narrow-complex PEA, naloxone could be considered after consultation with a BHP.

Answer: ASA is a safe medication with a wide therapeutic index (the effective dose without side effects can be from 80 – 1500 mg). The additional dose provided by paramedics will not exceed the therapeutic dose while ensuring the correct administration of correct dose of the medication. Therefore, apply the cardiac ischemia medical directive as if no care had been rendered prior to your arrival.

You may not be aware, but all calls that involve a Base Hospital Physician (BHP) patch are audited by the Local Medical Directors. Based on these audits, feedback may be given to a variety of individuals including paramedics, the BHPs and even physicians from admitting services regarding patients who may have recently been under their care. This feedback is given in attempts to improve patient care both at the level of the individual, but also at the level of the entire prehospital and hospital system.
BHPs are instructed to record your Run Number on each patch sheet in order to link it to the ACR. If unavailable at the time of the patch, please provide it as soon as feasible. Also, the patch sheet acts as a permanent record of medical orders. As a result, the BHP must be the only individual who records information on it.

A new version of the Base Hospital Physician patch form was released November 1, 2016. Here are a few key points to note about the new form:
- It’s now simplified and no longer has a patch form number; meaning you don’t need to ask for it anymore!
- The patch form is a Physician’s order and is to be completed by the Physician ONLY; meaning, please DO NOT add, attach or write any additional information on these forms.

Obtain blood glucose readings on patients presenting with an altered LOA, agitation, seizure or signs and symptoms of a stroke.
The Hypoglycemia Medical Directive should be utilized in patients meeting the following readings:
Age > 2 years: glucometry < 4.0 mmol/L
Age < 2 years: glucometry < 3.0 mmol/L

Cast as wide a net as you can… STEMI care starts with recognition, which requires capturing a 12-lead ECG as early as possible on any patient with possible ACS.
Perform a 12-lead ECG with the first set of vital signs on patients with any of these symptoms: chest discomfort (often described as a heaviness or pressure that may radiate into the left arm, jaw or shoulder), shortness of breath, nausea, vomiting, weakness, or syncope. STEMIs can sometimes present with atypical symptoms; especially in elderly, female, and diabetic patients. STEMIs also evolve and may not be evident on an initial ECG, so keep the leads connected and perform additional 12-leads during transport.
Also, keep in mind that prehospital ECG abnormalities may resolve by the time the patient receives a 12-lead in the Emergency Department. As a result, prehospital ECGs also have the potential to change the ED management of patients who are not experiencing a STEMI.
Also, remember to repeat an 12-lead when pain increases and mark on the 12-lead the patient’s pain scale, for example: “with x/10 pain). This helps interpret the 12-leads in hospital, even if there is no **ACUTE MI** or **STEMI**.

Case: A 39 year old male is found unresponsive. A bystander states they were going to try a new drug; his buddy went first. He presents with the classic signs and symptoms of opioid toxicity and his ventilation hasn’t improved following 3 doses of naloxone and ongoing assisted ventilation with a BVM. You’re still 20 minutes from the ED. You patch to the Base Hospital Physician (BHP), who orders 2mg of naloxone IN (provided you have it in stock).
What do you do?
Consider this: Written medical directives are considered offline medical control, and BHP patch orders are considered online medical control. BHPs can give orders that fall outside of the medical directives (online trumps offline) provided the intervention is within the paramedic’s scope of practice.
Now what do you do?
Yes, administer the 2mg of naloxone IN. Consider this a similar example to requesting additional nitroglycerin from a BHP for a patient who has ongoing ischemic chest discomfort following the administration of 6 doses. A higher dose in this case, is still within the paramedic’s scope of practice.
Keep in mind, however, that if a BHP directs a paramedic to perform an assessment or intervention that exceeds the paramedic’s scope of practice (for example, asking a PCP to administer epinephrine to a VSA patient), the paramedic must advise the BHP of such and notify the physician that he or she cannot comply with the direction as it exceeds his or her scope of practice.

Airway resistance is not constant but varies according to the relation:
where η is the dynamic viscosity of air; l and r are the length and radius of the airway respectively. Airway resistance depends greatly upon the size of the airway opening – inversely proportional to the fourth power of the radius.
Any disease affecting the respiratory tract has the potential of increasing airway resistance. Changes in airway resistance can occur suddenly and be sustained as in the case of an asthma attack or anaphylaxis. However, airway resistance can also vary between inspiration and expiration.
Patients with emphysema experience a destruction of the elastic tissue of the lungs which holds the small airways open. During expiration, particularly forced expiration, these airways may collapse causing increased airway resistance. Vigilance in monitoring patients’ breathing at all times is prudent.

When muscle tissue breaks down and cellular contents are released into the circulation, complications can ensue: compartment syndrome, peripheral neuropathy, acute renal failure, metabolic derangements, disseminating intravascular coagulopathy (DIC) and death.“Rhabdomyolysis is a clinical and biochemical syndrome that results from acute necrosis of skeletal muscle fibers and the leakage of cellular contents into the circulation” (Counselman, 2011).
When should we be considering rhabdomyolysis as part of our patient’s clinical picture? There are lots of causes and precipitating factors, including:
Trauma: crush injury, electrical or lightning injury, compartment syndrome, compression injury including prolonged pressure from own body weight (fall and can’t get up, coma of any origin, etc)
Exertional: heavy training or contact sports, delirium tremens, psychosis, excited delirium, seizure
Other: hyperthermia, heat stroke, drugs or toxins, infections, electrolyte disorders, sepsis
If your patient is potentially suffering from rhabdomyolysis, then establishing IV access would be an appropriate procedure.
Identifying patients who are at risk for rhanbdomyolysis and by initiating IV access can help prepare for potential complications that can be addressed in the prehospital setting (hypotension, arrhythmias, hyperk

The 2010 AHA Guidelines for ACLS recommend using quantitative waveform capnography in intubated patients during CPR. Waveform capnography allows providers to monitor CPR quality by optimizing chest compressions and can be used as a tool to help detect ROSC (return of spontaneous circulation) during CPR.
Two very practical applications of waveform capnography in CPR are:
1. Evaluating the effectiveness of chest compressions
Measurement of a low EtCO2 value (<10 mmHg) during CPR in an intubated patient may indicate that the quality of chest compressions needs improvement. High quality chest compressions are achieved when the EtCO2 value is at least 10-12 mmHg. If EtCO2 is less than 10 mmHg, determine if provider fatigue is occurring.
2. Assistance with the identification of ROSC
When ROSC occurs, there will be a significant increase in EtCO2 (~35-45 mmHg) which indicates a dramatic increase in cardiac output resulting in increased perfusion. The CO2 that accumulated during the cardiac arrest is now being transported to the lungs, is exhaled, and is measured by the EtCO2 detector.

SpO2 is one of many useful measurements used to build an understanding of patient status but like every other vital sign SpO2 must be critically evaluated each time you take it.Mechem (2015) cautions, “Interpretation of pulse oximetry readings mist account for a variety of factors that may artifactually influence the results. The best defense agaisnt these potential sources of error is a high index of suspicion”
In other words, it’s not an accurate SpO2 until you decide it is.
How SpO2 works: The probe emits two wavelengths of light from one side of the probe and measures the amount of each of those wavelengths that reaches the other side. As the light travels through blood in a finger the oxyhemoglobin absorbs one wavelength and deoxyglobin absorbs the other. The results are microprocessed into a percentage of bound Hb and presto: SpO2.
Remember, SpO2 is not a measure of overall patient oxygenation or wellbeing—you also need to consider if oxygen is being extracted at the cellular level. For example, in cyanide toxicity, the SpO2 is often normal, but cells are unable to extract oxygen from hemoglobin and cellular respiration is inhibited (cells are unable to utilize the oxygen that is present in the blood)
You should consider the following factors that render an SpO2 a potentially unreliable measure of patient oxygenation:
Color- other absorbent colors in the probe’s environment
- Nail polish and/or fake nails, particularyly dark colors, can alter SpO2 results
- Dark pigmentation of skin has affected readings in the past but newer technology has improved reliability in this regard
- Ambient lighting like fluorescent, infrared, incandescent can be picked up by the probe’s sensor
Reduce perfusion – other absorbent colors in the probe’s environment
- Inflation of BP cuff on same limb
- Elevation of limb
- Peripheral vasoconstriction due to hypothermia, medications, shock, injury
Abnormal hemoglobin situation
- Anemia—if there is less Hb overall in patient’s system then a 100% SpO2 isn’t reassuring
- Sickle hemoglobin—patients at particular risk of hypoxemia despite “normal” SpO2 reading
- Hypovolemia due to blood loss
- Poisoning—Hb carries stuff other than O2, and the SpO2 only measures if the Hb is bound, not whether it’s bound to actual O2. If something else has displaced oxygen on the Hb, the SpO2 can’t tell the difference. Carbon monoxide poisoning is an example (smoke inhalation or smokers). A life-threatening arterial desaturation can be masked by a falsely reassuring SpO2.
- Acidosis—when patient is acidotic there is an increased affinity between Hb and oxygen, meaning that although there may be a normal SpO2, cellular respiration may be altered as oxygen will not dissociate from hemoglobin. As a result, the hemoglobin retains oxygen, the SpO2 is normal, but cells are unable to extract oxygen and revert to anaerobic metabolism
- SpO2 is averaged over several seconds, therefore you may have a newly hypoxemic patient and the SpO2 has not yet caught up to the true reading. Think: hypoxia during intubation.
- Fit/displacement of probe—incomplete capture of both wavelengths of light can result from ill-fitting or slightly displaced probe resulting in falsely inflated or deflated readings.
If your defib isn’t configured to automatically display the SpO2 waveform you can dial it up easily on each call. A curvaceous waveform at least tells you the SpO2 reflects movement of blood through the patient’s finger.
So to recap: when you are measuring SpO2 you must always consider whether the result is actually a reliable measure of patient oxygenation or if it is CRAP!

Remember those “Four Stages of Learning”?
- Unconscious Incompetence: when you don’t know how little you know
- Conscious Incompetence: when you realize how little you know
- Conscious Competence: when you are mindful of every aspect of skill application
- Unconscious Competence: when you are so practiced that you can perform a skill without thinking about it
Well, no longer is Unconscious Competence the top of the food chain. It has been argued that stalling out in this fourth stage allows development of bad habits, complacency, loss of theory mastery and failure to keep up with emerging research and innovation.
A fifth stage of learning is being debated that embraces creativity, problem solving in novel situations and the pursuit of ongoing learning. This fifth stage has been called “Reflective Competence”, “Enlightened Competence” and “Conscious Competence of Unconscious Competence”. Essentially it means a skilled provider is aware of and nimbly avoids the traps of stage four complacency.
In which of your many skills do you practice this fifth stage of Reflective Competence?

The Bronchoconstriction Medical Directive states that, “nebulization is contraindicated in patients with a known or suspected fever or in the setting of a declared febrile respiratory illness outbreak by the local medical officer of health”.**a known fever is described by the BLS PCS as greater than 38 degrees Celcius (>38C)**
Patients with a temperature of >38 should NOT be treated with nebulized Salbutamol.

1. Gloves are PROTECTION. Gloves should only be used for what they do best – protecting you from the patient and protecting the patient from you.
2. Damage. Writing on your glove may compromise its structure and make it permeable to microscopic particles, like bacteria and viruses.
3. Cross contamination. In an ideal world, one person touches the patient and one member touches everything else to avoid cross contamination. Writing on your gloves compromises this if you’re the one caring for the patient.

When completing an ACR, paramedics encounter certain problem codes more frequently than others – some only occur several times per year across all of SWORBHP region.
Did you know that a problem/procedure occurring 125 times per year distributed randomly across SWORBHP region will only be encountered by a paramedic once every 5 years on average? Also, those problems/procedures occurring
Perhaps use this information as a reminder to double check infrequent problem codes when you enter them into your ACR. Accurate documentation is crucial to professional standards process, but also to your practice as a paramedic.

OPQRST is the beginning of a conversation about a patient’s pain. Don’t limit yourself to the six common questions. Use your patient assessment skills to learn more about the patient’s pain. This may help guide your treatments or give you a better understanding of what pathophysiological process is occurring.
Some additional questions might include:
- What were you doing when the pain started?
- Is your pain constant or intermittent?
- Has the pain been constant or has it gradually worsened?
- As your pain travels from the point of origin, how does it change?
- Have you experienced pain like this before? If yes, what was it?
- Have you done anything for your pain like pain medications, ice, or elevation?
- Are there positions or activities that make the pain better or worse?
- What else can you tell me about your pain?

Calculation of heart rate is important because a deviation from normal may affect the patient’s ability to maintain adequate blood pressure and cardiac output. There are several methods for calculating heart rate:
Six-Second Method: Count the number of QRS complexes within a 6 second strip (30 large boxes) and multiply by 10 to find the number of complexes in a minute.
For the following methods, the rhythm must be regular.
Large Boxes: Count the number of large boxes between one R-R interval and divide into 300.
Small Boxes: Count the number of small boxes between one R-R interval and divide into 1500.
Sequence Method: Select an R wave that falls on a dark vertical line. Number the next 6 consecutive dark vertical lines as follows: 300, 150, 100, 75, 60, 50. Note where the next R wave falls in relation to the 6 dark vertical lines = this is the heart rate.

Should this patient receive dimenhydrinate according to the Nausea/Vomiting Medical Directive?Answer: The correct answer is no. Diphenhydramine (Benadryl) has both antihistamine and anticholinergic properties. Diphenhydramine prevents the physiological effects of histamine by blocking H1 receptor sites. This provides symptomatic relief of allergic symptoms caused by the release of histamine.Dimenhydrinate (Gravol) also has both antihistamine and anticholinergic properties. In fact, its molecular structure is a combination of diphenhydramine and 8-clorotheophylline. Dimenhydrinate is used to diminish vestibular stimulation and depress labyrinthine function through its central anticholinergic activity (decreases vomiting secondary to motion sickness). It also depresses the chemoreceptor trigger zone in the hypothalamus to prevent vomiting. Gravol competes with H1 receptor sites due to antihistamine properties.
How does this information apply to YOU as a paramedic?Both medications have antihistamine and anticholinergic properties. As a result, a synergistic effect can occur if Gravol and Benadryl are administered together.Synergism occurs when two medications that have similar pharmacological properties are taken together (ie. two anticholinergic medications). The combined effect of these two medications is greater than the effect of the two medications administered alone (similarly to: 1+1=5). Neither drug by itself is necessarily harmful but together they have the potential to cause undesired side effects (sedation, hallucinations, agitation, tachycardia). This differs from potentiation which occurs when two drugs are taken together and the effect of one drug intensifies the other (a+b=B).

Arteriosclerosis is a chronic disease of the arterial system characterized by abnormal thickening and hardening and loss of elasticity of the vessel walls causing a decrease in blood flow. It is a term often used interchangeably with atherosclerosis.VS.Atherosclerosis
Atherosclerosis is a form of arteriosclerosis (and the most common), characterized by thickening and hardening of the arterial vessels through build-up of fat-like deposits (plaque). It is characterized by endothelial dysfunction, inflammation, and the build-up of lipids, cholesterol, calcium, and cellular debris within the intima of the vessel wall. This build-up results in plaque formation, vascular remodeling, acute and chronic luminal obstruction, abnormalities of blood flow, and diminished oxygen supply to target organs. When plaque within a lumen ruptures, acute ischemic events can take place (i.e. myocardial infarction, stroke)

Cold weather has crept into the region! Here are 7 simple tips to help keep your patients warm this winter:
1. Cover the patient with an insulating layer (thermal/regular blanket)
2. Insulate your patient from the ground. Remember cold floors (tiling, concrete and linoleum) are a quick way to lose body heat
3. Minimize the time that your backboard sits outside in the cold
4. Turn the heat on in the back of the truck BEFORE patient contact
5. For extended outdoor extrications, package IV & O2 tubing close to the body so that fluid/O2 are warm when entering the body
6. Maintain adequate temperatures in the back of the truck so medications don’t become cold or freeze
7. Ensure your patient is dry. Wet skin conducts heat faster and results in greater heat loss.

If your patient’s condition is improving on CPAP alone, there is no need to break the seal to administer Nitro. If, however, you feel your patient may benefit from Nitro use in addition to CPAP, go ahead, break the seal, administer the Nitro and reapply CPAP.
Nitro should NEVER be administered via MDI port on the CPAP device. This would cause inhalation of the medication, which is not recommended.
Nitro should ONLY be administered sublingually by spraying it under the patient’s tongue.

As a paramedic, there are many sources of stress: information overload, emotions, nervousness and that’s before you even clock into work! So, how do you manage all of those elements and still successfully treat your patient?The key is to remember these simple guidelines:
BLS before ALS: Remember, the basics are the foundation for everything else. What do we call a perfectly packaged trauma patient? A patient with multiple IVs, bandaging, splinting, and C-spine precautions; who ultimately died from mismanagement of the BLS airway? The answer: a mismanaged patient.
Try answering these questions when treating a patient:
- Is the airway secure?
- Is breathing adequate and oxygenation effective?
- How is their circulatory system?
Patient assessment: The cornerstone of a great paramedic is not about the “cool” things we do; it’s about the ability to provide a consistent, solid patient exam. After all, we can all do the same skills, the importance lies in the basics every time. So, when you’re feeling frustrated, just remember to start with the ABCs and a thorough exam.

A good question will usually get a good answer. A bad question almost always gets a bad answer. Surprised? Try the following patient assessment activity with your fellow co-workers:
Try to think of an ailment or injury that you are suffering from. Each person can ask one question. Start at one side of the room and work your way around the room answering each person’s questions.
If you are asked a yes or no question (i.e. “Do you have any allergies?”), then answer, “Yes” or “No”. If you are asked the better question (“What are your allergies?”), then list your allergies.
A sharp class will then ask the logical follow-up questions about your allergies:
Have you been exposed to any of those allergens?
- What happens when you are exposed?
- What treatment have you needed in the past for your allergic reaction?
- Real patients answer yes or no questions with yes or no answers.
In real life, good questions get good answers!

One of the most annoying things is trying to get a blood pressure in the back of one of our rigs: how are you supposed to hear it?
You can use the cardiac monitor with NIBP that gives you readings of 160/140, but is that accurate? Old, young, heavy, thin, pink or pale, everybody has a suspiciously normal blood pressure that always ends with a zero. What is just as bad is the medic who hesitantly stammers, “Uhhhh… 135/79?” Now let’s face reality…these simply are not true readings.
So, how do you get an accurate reading?
- Isolate the patient from everything else. Simply isolate the patient’s arm from touching anything else that it might come in contact with besides your cupped non –dominant hand under their elbow.
- Use the bell of your stethoscope, not the diaphragm.
- Use a good stethoscope.
- Turn your cuff upside down. This will prevent any annoying bumps against the head of your stethoscope. Upside down does not affect the accuracy of your findings.
- Learn to palpate. Sometimes you need to settle only for a rough systolic blood pressure.
- Turn everything off in the back of the truck. Get it as quiet as you can.

What should a paramedic do if a BHP patch is indicated but the BHP cannot be reached?
Answer: If a BHP patch is indicated and the BHP cannot be reached despite reasonable attempts by the paramedic to establish contact, a paramedic may initiate the required treatment without the requisite online authorization if the patient is in severe distress and, in the paramedic’s opinion, the medical directive would otherwise apply.
Link to Patching in the Medical Directives Handbook:
Remember, when sizing a King LT its 3, 4 and 5:
3 – (4 to 5 feet)
4 – (5 to 6 feet)
5 – (6 feet and greater)

You are dispatched to a Medical VSA. Should the air ambulance be triaged to respond as well if available?Successful resuscitation of a patient from a Medical Cardiac Arrest is listed as an indication, however responding to patients who are currently VSA from a medical arrest is not listed as a current indication. Many barriers exist to having air ambulances respond as a general rule to VSA patients (time on scene of land crews vs time for air ambulance to respond to scene, landing zones etc.).
For further information please see the BLS Patient Care Standards Air Ambulance Utilization Standard.

Now that we have your attention… when trying to remember how many ribs there are, you have to know how many vertebrae there are. Think of the common meal times, 7am, 12noon, and 5pm, which corresponds with breakfast, lunch and supper respectively. Of course you can enjoy ribs at any meal of the day. This also corresponds to the divisions between the vertebrae: cervical (7), thoracic (12), and lumbar (5). Each rib is associated with its own thoracic vertebrae, hence there are 12 pairs of ribs.Part 2: Land marking to decompress…Rib 1 is not palpable because it is buried under the clavicle and subclavian vessels. Therefore, when counting intercostal spaces, you always begin by land marking the second rib. This can be accomplished by locating the sternal angle (Angle of Louis). Think of the sternum as being a sword, it can be divided into three parts, the manubrium (the handle), the body, or gladiolus (the blade), and the xyphoid (the tip of the blade). The sternal angle is the palpable “step” that divides the handle and the blade. It marks the location of the second rib. Insertion of a needle for decompression should be performed at the lower part of the second intercostal space, to avoid damaging the vessel bundle that runs along the lower edge of each rib.Now you can “Take a Stab” at it!

Here is a tip and story to help you remember AV blocks (continuation).
Third Degree: The ventricles have no access to the atria and are left to their own devices to contract at 20 to 40 beats per minute. The atria, however, march along to their usual drummer at the normal sinus rate. (Don’t be fooled by P waves hiding inside the QRS complexes).
You have a few kids but end up divorced and go about your lives doing your own thing, HE IS ALWAYS THERE BUT YOU WANT NOTHING TO DO WITH HIM.
You will never look at blocks the same.

Here is a tip and story to help you remember AV blocks (continuation).
Second Degree Type 2: The P-R interval is consistent; it’s just not always followed by a QRS complex.
So you decide to have a talk with your husband. He says he is going to try to not be late. The next few times he goes out he’s back on time (PR 0.12-.20) then BAM HE DOESNT SHOW UP (missed QRS).
HE IS CONSTANT BUT THEN FOR NO REASON DOESNT SHOW UP.

Here is a tip and story to help you remember AV blocks (continuation).The P-R interval gets progressively longer until a QRS is dropped. You decided to marry the guy who is always late so he decides he’s going to test his boundaries when he goes out with his buddies. He says he will be back at 1200 and the first night he is, the next night he goes out he comes back later – 1 am, the next night is later – 2 am, then the next night he’s so late you lock him out of the house! HE IS PROGRESSIVELY LATE and GETS LOCKED OUT.
But there is something about him you like and you forgive him and the cycle continues…late…late…late… locked out for the night!
Remember Wencke always comes bach!

Here is a tip and story to help you remember AV blocks.
First Degree: Look at the P-R interval, if it is longer than 0.20 seconds, it’s a first-degree AV block.
You are dating a guy and you tell him to pick you up at 8. Instead he picks you up at 8:30. This happens consistently every time you go out. HE ALWAYS SHOWS UP BUT IS CHRONICALLY LATE.
