ABA ADVANCED Exam study guide
ABA ADVANCED Exam · Work through your exam, one topic at a time.
The ADVANCED Exam is the second of three examinations in the American Board of Anesthesiology's initial certification pathway. The ABA describes candidates for certification as taking "a series of three exams: BASIC, ADVANCED and APPLIED," so the ADVANCED Exam sits between the foundational-science BASIC Exam and the APPLIED Exam, which assesses applied practice. It is written for anesthesiologists who are near the end of, or have recently completed, accredited residency training and are moving from isolated science recall toward clinical judgment. Content concentrates on basic science as it is used at the bedside. Topics on this exam: Basic Sciences Applied to Anesthesiology (physics, equipment, monitoring), Pharmacology, Physiology and Pathophysiology, and Clinical Anesthesia Management. The ABA ADVANCED Exam study guide has 4 sections and about 1,324 words.
01Basic Sciences Applied to Anesthesiology: Physics, Equipment, and Monitoring
Start with flow and pressure models, because exam questions often disguise simple relationships. Laminar flow follows Poiseuille's law, so resistance rises with the fourth power of radius and depends on viscosity; turbulent flow depends on density and the square of velocity. The Bernoulli principle explains pressure drops at a stenosis, while the Venturi effect explains entrainment of air or nebulized drug. A variable-bypass vaporizer splits fresh gas between a vaporizing chamber and a bypass channel; its output depends on fresh gas flow, temperature, and carrier gas, and it can deliver an unintended concentration if filled with the wrong agent.

Organize pharmacology around pharmacokinetics and pharmacodynamics. Volume of distribution determines loading dose; clearance determines maintenance rate; context-sensitive half-time describes the time for plasma concentration to fall by half after an infusion stops. Propofol is highly lipophilic, causes dose-dependent hypotension, and has antiemetic properties. Etomidate preserves hemodynamics but transiently suppresses cortisol synthesis.

Oxygen delivery is cardiac output multiplied by arterial oxygen content. Arterial content depends mainly on hemoglobin and saturation; dissolved oxygen is tiny. The oxyhemoglobin curve shifts right with acidosis, hypercapnia, fever, and elevated 2,3-DPG, reducing affinity and improving tissue unloading, but reducing arterial saturation at a given PaO2. Pulse oximetry estimates saturation, not content, and cannot detect anemia or hyperoxia.

Clinical management questions test systematic preparation more than isolated facts. Preoperative assessment identifies airway risk, aspiration risk, cardiopulmonary reserve, allergies, and medication interactions. Fasting guidelines reduce aspiration risk; clear liquids are generally permitted up to two hours before induction, while light meals require longer. A difficult-airway plan includes preoxygenation, awake fiberoptic intubation when indicated, video laryngoscopy, supraglottic rescue, and front-of-neck access.
