At what rate should mouth to mouth or mouth to nose artificial respiration be rendered to an adult?

The recommended rate for mouth-to-mouth or mouth-to-nose artificial respiration in adults is indeed 12 to 15 times per minute. This rate is designed to provide sufficient oxygenation to the lungs while mimicking normal breathing patterns. It allows for an effective exchange of air to help restore adequate oxygen levels in a person who is not breathing.

Breaths should be delivered at this rate to optimize the chances of resuscitating the individual while preventing potential complications, such as hyperventilation, which can lead to decreased cardiac output and other issues. The guideline emphasizes a balance between providing enough breaths per minute without overwhelming the lungs. This approach is supported by various health organizations and reflects best practices in emergency response training.
