nasal cannula debate

[VentMedic]

Hehe... except for RTs, my students are the only medics I've ever known to understand how to estimate the FiO2 delivered by an N/C. It's a crime that more don't.

And most don't understand the textbook "guessimate" values are for the 75 kg person breathing a calm 500 ml VT at a rate of 12 - 16.

2 L/M or 28% means little to someone who is tachypneic. 6 L/m means little to someone in respiratory distress and tachypneic who could seriously use a steady FiO2 of 0.40 but ain't gonna get it.

Yep. Tis like the approximation of percentage of perfusion provided by CPR. It applies only to perfect, textbook CPR, not what most victims end up receiving.

You mean to tell me what the book says, isn't what really happens? Do I need to start learning EMS from tv shows now?

[VentMedic]

I think it would be a great experience for EMT(P) students to spend a few hours in a Pulmonary lab donating their nares to research for new O2 devices and checking the FiO2 by sampling with a nasal catheter.

Agreed .... donate nares ... nah mandatory nasal catheter, I will buy.

Ok I know your making jest BUT it depends on what books you read, there is a plethora of respiratory text books out there dont restrict yourself to the dummied down EMS books ... well accept for Bledsoe's books that is.
