Figure 3From: The dynamic pattern of end-tidal carbon dioxide during cardiopulmonary resuscitation: difference between asphyxial cardiac arrest and ventricular fibrillation/pulseless ventricular tachycardia cardiac arrestEnd-tidal pCO2 during cardiopulmonary resuscitation regarding aetiology of cardiac arrest and outcome. PetCO2 during cardiopulmonary resuscitation. Asphyxial with ROSC (black bar), asphyxial without ROSC (white bar), VF/VT with ROSC (dotted bar) and VF/VT without ROSC (gray bar). Data are presented as mean values with one standard deviation. P-values were calculated by unpaired t-test for each time period and show above bars. CPR, cardiopulmonary resuscitation; PetCO2, partial pressure of end-tidal carbon dioxide; ROSC, return of spontaneous circulation.Back to article page
