Question: I think a lot of paramedics have trouble telling the difference between pulmonary edema (CHF) and bronchoconstriction now. If we had capnography nasal sensors, you could see that the wave form is still flat on top for the CHF while the bronchoconstriction has the shark tooth pattern. This could be a good tool for all paramedics to learn pulse ox without capnography. It is like looking at the heart rate with out and EKG. This should be taught to all paramedics, what do you think? As of now we do not have the nasal sensors, only the ET hook ups.
