What is the proper ratio of cardiac compressions to artificial ventilations?

The proper ratio of cardiac compressions to artificial ventilations during cardiopulmonary resuscitation (CPR) for adults is 30 compressions to 2 ventilations. This ratio is recommended for single-rescuer CPR to maximize the effectiveness of chest compressions while still providing necessary ventilations.

In this context, 30 compressions focus on maintaining circulation to vital organs by generating blood flow, while the 2 ventilations help provide oxygen to the lungs. This method creates a systematic approach that allows rescuers to maintain a strong and effective rhythm during the critical moments of resuscitation.

Other ratios, such as 15 to 2, are typically used for specific circumstances, such as two-rescuer CPR for children and infants, or during scenarios where the emphasis might shift between compressions and ventilations based on the patient's needs or age. Therefore, the 30 to 2 ratio remains the standard for adult resuscitation, ensuring a higher survival rate in critical situations.
