During CPR for an adult, how many breaths do you give after every cycle of compressions?

In adult CPR, the protocol involves delivering two rescue breaths after every 30 compressions. This is designed to ensure that the patient receives adequate oxygenation while maintaining the circulation provided by chest compressions.

Following the compression cycle, delivering two breaths allows for effective ventilation and helps address hypoxia, which is critical in an emergency situation where the individual is not breathing efficiently on their own. The technique involves sealing the mouth-to-mouth for breaths or using a barrier device if available, ensuring that the breaths are delivered effectively to expand the lungs.

This approach is part of the conventional CPR guidelines, which emphasize the combination of compressions and ventilations to maximize the chances of survival in a cardiac arrest scenario. Thus, the two breaths following the 30 compressions are integral for restoring oxygen levels in the blood, enhancing the likelihood of a successful outcome.
