Background: Volumetric capnography is increasingly being applied in cardiopulmonary resuscitation. However, during cardiopulmonary resuscitation, the abnormal ventilation state affects the monitoring effect of the most commonly used capnography-derived parameter, the partial carbon dioxide end-tidal pressure (PetCO). In this study, we evaluated the ability of a new volumetric capnography-derived parameter, the ratio between the PetCO and the volume of carbon dioxide (CO) eliminated per min and per kilogram of body weight, for detecting hyperventilation during cardiopulmonary resuscitation.
