Cardiopulmonary Resuscitation (CPR) Practice 2025 - Free CPR Practice Questions and Study Tips.

A basic life support (BLS) cycle typically consists of performing CPR for two uninterrupted minutes before re-evaluating the situation, which includes checking for signs of life and assessing the need for further intervention. This timeframe allows the rescuer to effectively perform chest compressions and rescue breaths in a consistent manner, which is crucial for maintaining blood circulation and oxygenation to vital organs during a cardiac arrest.

The emphasis on uninterrupted compressions is essential because it maximizes the chances of a successful outcome. Frequent interruptions can lead to a decline in the effectiveness of CPR due to the lack of continuous blood flow. Therefore, the two-minute period is a standard guideline in CPR protocols, ensuring enough time for the rescuer to deliver an adequate amount of compressions and rescue breaths to increase the likelihood of patient survival until advanced medical help arrives.
