Question: I have a question about a call. Male patient severe SOB. Crackles throughout with a GCS of 4, suspected acute pulmonary edema. Obviously patient of out nitro protocol. Patient’s spo2 31 and 42% with mottling noted. Patient’s initial pulse 42 with a respiration rate of 33. CPAP is contraindicated at this time so ventilations assisted via BVM. Enroute patient’s GCS improves to 15 and spo2 increases to 99% with ventilation assist. At this point could CPAP be applied or is it like the nitro protocol, once your out your out?
