What is the rationale for minimizing interruptions in chest compressions during resuscitation?

• A. Interruptions reduce coronary perfusion pressure and lower survival
• B. They increase coronary flow
• C. They do not affect outcome
• D. They shorten resuscitation time

Answer: (A)

During resuscitation, chest compressions generate the pressure that drives blood to the heart and brain. Coronary and cerebral perfusion depend on diastolic pressures created by those compressions. When you pause, that pressure quickly falls, reducing coronary blood flow and the amount of oxygen delivered to the brain. This drop in perfusion lowers the chances of return of spontaneous circulation and overall survival. So the goal is to keep compressions going with as few interruptions as possible, only pausing briefly for essential tasks like rhythm checks or defibrillation and then resuming immediately. Interruptions don’t increase coronary flow; they actually reduce it, and they can worsen outcomes and prolong the resuscitation effort.
