Abstract Introduction There has been increased interest in the use of capnometry in recent years. During cardiopulmonary resuscitation CPR the partial pressure of end-tidal carbon dioxide PetCO2 correlates with cardiac output and consequently it has a prognostic value in CPR. This study was undertaken to compare the initial PetCO2 and the PetCO2 after 1 min during CPR in asphyxial cardiac arrest versus primary cardiac arrest. Methods The prospective observational study included two groups of patients cardiac arrest due to asphyxia with initial rhythm asystole or pulseless electrical activity and cardiac arrest due to acute myocardial infarction or malignant arrhythmias with initial rhythm ventricular fibrillation VF or pulseless ventricular tachycardia VT . The PetCO2 was measured for both groups immediately after intubation and then repeatedly every minute both for patients with and without return of spontaneous circulation ROSC . Results We analyzed 44 patients with asphyxial cardiac arrest and 141 patients with primary cardiac arrest. The first .
