During rescue breathing for an adult, how many breaths should be given after 30 compressions?

During rescue breathing for an adult following the provision of 30 chest compressions, the recommended protocol is to administer 2 breaths. This is based on the established guidelines for cardiopulmonary resuscitation (CPR) which emphasize that after every cycle of 30 compressions, it is important to provide adequate breaths to ensure that oxygen reaches the lungs and is delivered to the bloodstream.

Each breath should be given over a duration of approximately 1 second and each breath should be sufficient enough to make the chest rise visibly. Adequate ventilations are critical to increase the likelihood of survival in cases of cardiac arrest when the heart is not pumping effectively. Giving 2 breaths after 30 compressions balances the need for both chest compressions and artificial ventilation, contributing to the establishment of an effective CPR rhythm that helps to maintain the oxygenation of vital organs.
