We discussed that in class. Here's a simple test. Put a pulse-ox on your finger. Hold your breath for as long as you can. See how much the number changes.
Still, the National Registry says thirty seconds or else.
Yeah it takes a few minutes for pulse-ox to change. That is why with any pt. with a respiratory component I used end-tidal CO2 so I can tell immediately that they are not breathing.
