One of the biggests problems I have with the Falcon 200 is the engines. Yes, there is presently MSP available, but I have heard rumors that the day the US Coast Guard parks their last Falcon, Garrett will stop supporting the engine. There are not enough of those engines out there for anyone to consider supporting it on their own.
I have done medievacs for many years. Generally the patient is stable before they leave for transport. Even when they are being moved from poor care to a much better facility, they are more or less stable before moving.
So a Lear would be usable. My experience with medical teams are that they wouldn't be happy unless they were in a BBJ with a full surgical suite.
