What is the recommended ratio of compressions to rescue breaths during CPR for adults?

The recommended ratio of compressions to rescue breaths during CPR for adults is 30:2. This means that for every 30 chest compressions performed, you should give 2 rescue breaths. This ratio is based on guidelines that focus on maximizing blood circulation to vital organs during cardiopulmonary resuscitation.

The 30:2 ratio is chosen to provide an effective blend of chest compressions, which are crucial for maintaining blood flow, and rescue breaths, which deliver oxygen to the lungs. Compressions should be done at a rate of about 100 to 120 per minute, allowing for quick and continuous blood circulation. Following every 30 compressions, delivering 2 rescue breaths allows for the person receiving CPR to receive oxygen, which is essential for preventing brain damage and enhancing the chance of survival.

Other ratios, such as 15:2, are no longer recommended for adults, as research has shown that the 30:2 ratio optimizes the balance of compressions and breaths for better outcomes. Ratios like 10:1 and 20:2 are not supported by current guidelines and could lead to insufficient oxygenation and perfusion during a critical emergency. Thus, adhering to the 30:2 ratio is vital for effective
