Stomach inflation during cardiopulmonary resuscitation in out-of-hospital cardiac arrest patients: Where did the air go?

We read with great interest the article by Naito and colleagues1 which aimed to study the effect of stomach inflation during cardiopulmonary resuscitation on return of spontaneous circulation in out-of-hospital cardiac arrest patients. The authors used patients with a gastric volume  ≥ the 75th percentile in their cohort as the cut-off value for defining the group with gastric distension. Gastric volumes for this group considered to have gastric distension ranged from 793 to 2673 ml. It is accepted in the literature that in an unprotected airway, about half of applied minu te ventilation usually enters the stomach.
