I'm interested in the acute changes/manipulation of cardio/pulm physiology, giving a patient a drug and seeing an immediate effect, resuscitation, and crisis situations. So naturally I'm drawn to gas and EM, but I fully realize how precarious of a position both of these fields are in. I am simply not interested in completing the brutal training required to become a surgeon and living in the hospital. Cutting people open and standing in one spot for hours on end, no matter the body part, has no appeal to me. I've thought about ophtho and IM subspecialties. Ophtho is facing real encroachment from optometrists, however, and IM subspecialties require suffering through an IM residency and 6+ years of post grad training.
