What CRNA Interviewers Actually Want to Hear About Vasopressors

Understanding vasopressors for CRNA interviews means going beyond what each drug does — interviewers want to know why it does it, at the receptor and cellular level. This episode walks through the mechanism of action for norepinephrine, epinephrine, phenylephrine, vasopressin, dobutamine, and milrinone, tracing each drug from receptor binding through intracellular signaling to the clinical effect at the bedside.
