Answer:
As an anesthesiologist you simply are the person who puts the patient under anesthesia for surgery, and check the patients vital signs while he/she is in surgery. And if at any time the anesthesiologist sees anything unusual he/she would tell the surgeon immediately. Also they are to visit with the patient before the surgery to determine if the patient is good enough to undergo the surgery that he/she is about to participate in. The anesthesiologist is also supposed to check up on the patient after words to check if the patient is recovering normally.
