•GIVEN that FDA’s mission is to regulate all medical drugs and devices used to diagnose, treat or
prevent disease

•WHY does FDA regulate oxygen and nitric oxide gases but not CO,
despite the widespread use of CO by respiratory therapists in DLCO lung function testing
at 3000 ppm?
•3000ppm is more than twice the 1200ppm that NIOSH deems “Immediately Dangerous to Life &
Health” and 15
times the level at which NIOSH recommends the immediate evacuation of any workplace!
