Howdy all,

I'm doing my FIRC (Flight Instructor Refresher Course so we are all on the same page) online through AOPA. I am looking at aeromedical stuff right now, and they recommend a pulse oximeter. I guess I've casually thought about them in the past, but for whatever reason a light bulb seems to be going off in my head now. Does anyone on here use a pulse oximeter for flying?

Thanks!
