Administering more than 10 breaths per minute during CPR can lead to a drop in end-tidal carbon dioxide (ETCO2) levels. This occurs because excessive ventilation can hinder the natural circulation and gas exchange processes. When breaths are delivered too quickly, it can result in inadequate time for oxygen to effectively diffuse into the bloodstream and for carbon dioxide to be expelled. This imbalance can compromise the effectiveness of chest compressions, which are critical in maintaining circulation and promoting effective oxygen delivery to vital organs.

In contrast, maintaining a slower, more rhythmic ventilation rate—typically between 10 to 12 breaths per minute—allows for better synchrony with chest compressions, optimizing both oxygen delivery and carbon dioxide removal, which is crucial for successful resuscitation efforts.
