Fewer and shorter interruptions in chest compressions are associated with:

The correct answer highlights that fewer and shorter interruptions in chest compressions are associated with better outcomes in cardiac arrest scenarios. Continuous chest compressions are crucial for maintaining blood flow to the brain and other vital organs during a cardiac emergency. When compressions are performed with minimal interruptions, the likelihood of achieving return of spontaneous circulation (ROSC) increases significantly.

Research in emergency medicine emphasizes that high-quality cardiopulmonary resuscitation (CPR), characterized by uninterrupted compressions, leads to improved survival rates and neurological outcomes for patients who experience cardiac arrest. This understanding drives guidelines for CPR training and emergency response protocols, reinforcing the importance of minimizing pauses during chest compressions to enhance the chances of a positive result for the patient.
