No, they didn't. Here's the dirty secret about most MD's. Their primary role is diagnostic and setting a treatment plan. Their actual clinical skills tend to be unbelievably narrow, generally limited to certain day to day practices. and They have never touched any piece of equipment outside of their very very narrow range, since med school. Doctors have no idea about Vent's, and are useless at getting a tube in, unless they are an Anesthesiologist or a rare Emergency Medicine specialist. That's what Respiratory Techs are for. MD's do not touch the hardware. (Certainly not if the rest of the Medical Staff can prevent it. ) Doc's are great at things like bitching about X-Rays. Not one could ever however take one themselves. They would not know where to start. Want to see some fun. Watch the look of viscous delight on the Nurses faces when a patient demands that they want "The Doctor" to start their IV. (Yeah, that's a request they soon regret.) I haven't started an IV in 20 years. I can still do it backwards one handed and blindfolded and do it better than any of the three dozen MD's I work with. Outside of Surgeons, most Physician's don't really get into the physical side of Medicine Practice. Beyond things like scoping, catheterizing and examining. Heck very few even have to do suturing anymore. That's what PA's are for. And they almost never touch the high tech toys. Giving an MD an Orientation on a Ventilator is a pointless waste of time. They won't remember it by tomorrow. Other people are for remembering things. They're DOCTORS!
