However, achieving the correct ventilation rate and volume is more complicated than it seems. Too much air can cause over-ventilation, leading to increased pressure in the chest, which impairs blood return to the heart. On the other hand, too little air can result in hypoxia, depriving the organs of necessary oxygen. Proper ventilation during resuscitation is a delicate balance, and that’s where feedback devices, like the EOlife X, become invaluable.
