What is the proper technique for performing CPR on an adult?

The proper technique for performing CPR on an adult involves delivering 30 compressions followed by 2 breaths. This method is in alignment with the guidelines provided by organizations such as the American Heart Association. The rationale behind this specific ratio is grounded in the need for both effective chest compressions and ventilation to ensure that oxygen-rich blood is circulated to vital organs, particularly the brain and heart.

The sequence begins with compressions, which help to mechanically pump blood throughout the body. Compressions should be performed at a rate of 100 to 120 per minute and at a depth of at least 2 inches to ensure adequate circulation. After 30 compressions, administering 2 breaths allows for the delivery of oxygen directly into the lungs, further supporting the patient's need for oxygen during a cardiac arrest situation.

In summary, the choice of 30 compressions followed by 2 breaths strikes a critical balance between providing sufficient blood flow and ensuring oxygenation, which is essential for maximizing the chances of survival and recovery for an adult experiencing cardiac arrest.
