The Perils of Hyperventilation
More is not better!
Higher respiratory rates and/or excessive volumes during manual resuscitation result in the increased likelihood of morbidity and mortality. Studies indicate that hyperventilation is happening at alarming rates and frequencies both inside and outside of hospital settings. The longer the period of hyperventilation, the more likely the patient is to experience related complications such as...

1. Decreased likelihood of survival
2. Cerebral hypoxia resulting in a corresponding decrease in the chances of baseline neurological outcome and increased chances of permanent neurological damage
3. Reduced cardiac output and blood pressure
4. Gastric inflation resulting in emesis, aspiration and subsequent pneumonia
5. Lung damage
