Learning objectives
- 1Describe the PCARR classification system for perioperative cardiac arrest causes and how it categorizes events based on physiological determinants of cardiac output.
- 2Analyze causes of perioperative cardiac arrest according to preload, contractility, afterload, and rate or rhythm crisis categories, including specific examples and mechanisms.
- 3Demonstrate systematic diagnostic approaches for identifying perioperative cardiac arrest causes, including monitoring data, the A-SERCH framework, and the Hs and Ts mnemonic.
