Vent,
I'm curious about this, too... is this documented, or just your experience? The study you posted seemed to judge the HT50 adequate as a transport and EMS/Military vent.
The term adequate is relative to the patient and the provider. I could probably transport a patient on an ATV, with me being a very unhappy provider, but I would have to be very pharmacologically proficient to adjust for whatever the situation called for. Unfortunately, there are many ICU patients that can not tolerate even bagging, which is also not preferred for transport, and require the higher level technology.
