What is the recommended ventilation rate for an adult during bag-valve-mask ventilation?

Deliver about one breath every 5–6 seconds, which is roughly 10–12 breaths per minute. This rate provides enough tidal volume to oxygenate without pushing air too rapidly into the stomach or raising intrathoracic pressure excessively. Rapid breaths can cause gastric insufflation, increase the risk of vomiting/aspiration, and reduce venous return and cardiac output, especially during resuscitation. A steady pace that produces visible chest rise confirms adequate ventilation and helps avoid both under- and over-ventilation.
