Yes, absolutely.
The thing I'm an international expert on is teaching ultrasound to rank beginners. I've taught 8,000 Canadian physicians how to use ultrasound; they had never picked up an ultrasound probe, ever, in their lives. At this point in Canadian emergency medicine, I would say if you're not using ultrasound daily, you're a dinosaur looking for a tar pit to fall into.
So yes, it can be done. Among those 8,000 doctors, I guarantee you there were some who were pretty slow and much less sharp than my medics. Yes, we can be using it.
The other thing I would tell you is that I went to see the operation at Downsview. To be honest with you, what we need is off the shelf right now. There is an ultrasound unit on the market right now that's half the size of a pitcher of water, and it will tell me if the lung has dropped, if there's bleeding in the chest, bleeding in the abdomen, around the heart, very effectively, within seconds. And I can teach a medic how to do that in about 10 hours. So that's out there.
