During CPR, how many sets of compressions and breaths are given?

The guideline for CPR in adults specifies delivering a set of 30 compressions followed by 2 rescue breaths. This sequence ensures that the victim's heart is being kept active through compressions, providing necessary blood flow while also allowing for ventilation to deliver oxygen. The 30 compressions are crucial for maintaining circulation, as they create pressure in the chest cavity, effectively pumping blood to vital organs. The 2 breaths following the compressions help to supply oxygen to the lungs, which is essential for cellular function and survival.

Maintaining this cycle of 30 compressions and 2 breaths allows for an effective rhythm that maximizes the chances of resuscitation before medical personnel arrive. This method is standardized by organizations such as the American Heart Association to ensure that CPR is performed consistently and effectively by bystanders and first responders.
