![]() Using the same method, we found that bystander CPR, witnessed arrest, final PetCO2, initial PetCO2 and resposne time were associated with survival. The univariate analysis for ROSC on admission (Table 1) showed that initial PetCO2, ventricular fibrillation or pulseless ventricular tachycardia as the initial rhythm, witnessed arrest, bystander-performed CPR, female sex and response time were associated with ROSC. CPC, cerebral performance category CPR indicates cardiopulmonary resuscitation EMS, emergency medicine services PEA, pulseless electrical activity ROSC, restoration of spontaneous circulation VF, ventricular fibrillation VT, ventricular tachycardia. Utstein reporting template for out-of-hospital cardiac arrest obtained over an 8-year period. n = 82Īrrest witnessed/monitored n = 472 Arrest not witnessed n = 265Īny defibrillation attempt n = 406 Chest compressions n = 737 ![]() Results PetCO2 after 20 minutes of advanced life support averaged 0.92 ± 0.29 kPa (6.9 ± 2.2 mmHg) in patients who did not have ROSC and 4.36 ± 1.11 kPa (32.8 ± 9.1 mmHg) in those who did (P 16 min. Minutes of standard advanced cardiac life support would predict restoration of spontaneous circulation (ROSC). We hypothesized that an end-tidal carbon dioxide level of 1.9 kPa (14.3 mmHg) or more after 20 Data according to the Utstein criteria, demographic information, medical data, and partial pressure of end-tidal carbon dioxide (PetCO2) values were collected for each patient in cardiac arrest by the emergency physician. The patients were intubated and measurements of end-tidal carbon dioxide taken. Methods This is a prospective, observational study of 737 cases of out-of-hospital cardiac arrest. Changes in expired end-tidal carbon dioxide levels during cardiopulmonary resuscitation (CPR) may be a useful, noninvasive predictor of successful resuscitation and survival from cardiac arrest, and could help in determining when to cease CPR efforts. An ability to predict cardiac arrest outcomes would be useful for resuscitation. Higher survival rates have been observed only in patients with ventricular fibrillation who were fortunate enough to have basic and advanced life support initiated soon after cardiac arrest.
