NPLQ 10th Generation Practice Test

During CPR, the recommended compression to rescue breath ratio for adults is 30 compressions followed by 2 rescue breaths. This approach is established based on guidelines designed to maximize blood circulation and oxygenation during cardiac arrest situations.

The rationale behind the 30:2 ratio is to ensure that the victim receives an adequate number of compressions, which helps maintain blood flow to vital organs. The compressions are critical because they manually pump the heart, allowing for artificial circulation. Following the compressions with two rescue breaths then provides the necessary oxygen to the lungs, supporting the body's need for oxygenated blood.

Adopting this sequence during CPR has been shown to improve survival rates and outcomes, making it a critical component of effective resuscitation practices. It's important to perform this cycle continuously until emergency medical services arrive or the individual shows signs of life.
