ABA BASIC study guide
ABA BASIC · Work through your exam, one topic at a time.
BASIC is the first in the sequence of three initial certification examinations that the American Board of Anesthesiology (ABA) administers to physicians seeking board certification in anesthesiology - the others being ADVANCED and APPLIED. It is intended for anesthesiology residents who have completed the core clinical anesthesia training that precedes the more advanced and applied stages of the certification pathway, and it functions as a knowledge examination rather than a simulation or oral assessment. The ABA BASIC study guide has 4 sections and about 1,650 words.
01Basic Sciences: Physics, Pharmacology, Physiology, Anatomy
Gas behavior underlies the anesthesia machine. Boyle's law (P·V constant at fixed temperature) explains bellows and ventilator function; Graham's law explains why CO2 diffuses roughly 20 times faster than O2 across the alveolar membrane; Henry's law explains why a highly blood-soluble gas such as N2O enters air-filled spaces faster than nitrogen leaves them, expanding a pneumothorax, bowel gas, or middle-ear cavity.

Frame every preoperative question around three outputs: risk of the patient, difficulty of the airway, and the plan for the case. Functional capacity is the strongest simple discriminator - the ability to climb a flight of stairs or do heavy housework represents at least 4 METs and generally supports proceeding without further cardiac testing.

After roughly 20 weeks of gestation, aortocaval compression dominates positioning decisions: left uterine displacement is mandatory during induction and maintenance. Neuraxial anesthesia is generally the preferred technique for cesarean delivery, including in preeclampsia, unless there is coagulopathy, infection at the site, or severe volume depletion.

The Swiss cheese model describes accidents as failures of multiple defensive layers aligning. A near miss causes no harm and is still reportable; an adverse event is harm regardless of preventability; an error is a deviation from intended action.
