How many rescue breaths should be given after 30 compressions?

In the context of high-quality CPR for adults, after delivering 30 chest compressions, the rescuer is instructed to give 2 rescue breaths. This ratio is essential for providing adequate ventilation to the patient. Each rescue breath should last approximately 1 second and result in visible chest rise.

Following this procedure is crucial because chest compressions help circulate blood, while rescue breaths provide oxygen to the lungs. The 30:2 compression-to-breath ratio is designed to balance the two components effectively, ensuring that the victim receives sufficient oxygenation without excessively delaying chest compressions. Maintaining this balance increases the chances of survival and can improve overall outcomes during cardiac arrest scenarios.
