What Does an Anesthesiologist Assistant Do?
As an anesthesiologist assistant, your day revolves around keeping patients safe before, during, and after surgery. You'll perform preoperative assessments, calibrate anesthesia delivery systems and monitors, administer anesthesia under physician anesthesiologist direction, and manage airways through intubation and ventilatory support. Throughout each procedure, you monitor EKG, arterial pressure, blood gases, and vitals — ready to respond with CPR, ACLS, or PALS if emergencies arise. You also assist with invasive monitoring like arterial lines, administer blood products and fluids, and document all patient care. Every case happens within the physician-led Anesthesia Care Team.
If you're comparing career paths, here's the key distinction. CAAs work exclusively under the direction of a physician anesthesiologist within the Anesthesia Care Team model — that's the only way they practice. CRNAs are advanced practice registered nurses who specialize in anesthesia and may have independent practice authority in some states. Anesthesiologists are physicians (MD or DO) who lead the anesthesia care team with full independent authority. Both CAAs and CRNAs are highly skilled providers considered clinically equivalent, but their educational paths differ. CAAs follow a pre-medical track, while CRNAs follow a nursing track into anesthesia.
