What is the correct compression-to-breath ratio for adult CPR?

The correct compression-to-breath ratio for adult CPR is 30 compressions to 2 breaths. This ratio is part of the guidelines set forth by the American Heart Association and is used during both single-rescuer and multi-rescuer situations for adult victims of cardiac arrest. The 30:2 ratio is designed to maximize blood circulation and facilitate effective ventilation during CPR.

When performing chest compressions, it's essential to do so at a rate of 100 to 120 compressions per minute, followed by two rescue breaths. This approach ensures that adequate oxygen is delivered to the victim's lungs while also maintaining blood flow to vital organs, significantly increasing the chances of survival and recovery.

The focus on a 30-compression cycle followed by breaths emphasizes a more comprehensive approach to resuscitation, balancing the need for continuous circulation with the critical provision of oxygen. This method has been proven effective in emergency situations where time is of the essence, and quick, efficient actions can save lives.
