Pediatric Cardiac Arrest Practice Test

Rhythm checks in pediatric CPR are done in a two-minute cycle, with an immediate check after a defibrillation shock. This cadence lets you continuously provide high-quality chest compressions while still re-evaluating the heart rhythm to decide if another shock is needed or if return of spontaneous circulation has occurred. Why this interval works: a 2-minute cycle fits with the CPR rhythm that balances movement of blood with timely rhythm assessment, and checking right after a shock ensures you respond promptly to the post-defibrillation state (whether another shock is indicated or you should continue CPR). Checking more frequently (every 30 seconds) would cause unnecessary pauses in compressions, while waiting five minutes would delay crucial reassessment. Checks are not limited to moments when compressions pause; they’re performed at the defined interval and right after defibrillation to guide the next steps.
