Just wanted to say I agree about the RCPs--it is really a way for them to excel! I myself did not have that type of background--but a lot of students (and professors/directors of the programs) started out that way and do extremely well. I wouldn't say you are at a disadvantage not having that sort of job experience, but sometimes I will admit it makes me a little jealous that I didn't come in knowing respiratory physiology and information about the equipment.
