How many chest compressions are recommended for adults in CPR?

In adult CPR, the recommended number of chest compressions is 30. This guideline is established to ensure that the individual performing CPR can effectively circulate blood and deliver oxygen to vital organs until emergency medical services arrive or the individual is otherwise stabilized.

The rationale behind performing 30 compressions in a cycle, followed by two rescue breaths, is based on research and evidence showing that this ratio maximizes blood flow and oxygen delivery during the critical early minutes of cardiac arrest. The compression rate should ideally be between 100 to 120 compressions per minute, which emphasizes the need for both quantity and quality in chest compressions to be effective. Maintaining the proper rhythm and depth during compressions is essential to increase the chances of survival for a person in cardiac arrest.

Understanding this ratio is vital for anyone trained in CPR, as it contributes significantly to the effectiveness of the resuscitation effort.
