They conclude that below-threshold levels of 14 mmHg kPa measured after 20 minutes of cardiopulmonary resuscitation reliably predict that spontaneous circulation cannot be restored. In their report on 737 patients who sustained out-of-hospital cardiac arrest collected over an interval of 9 years in a well-organized emergency medical system Kolar and colleagues confirmed that the measurement of end-tidal carbon dioxide tension PetCO2 is predictive of the outcomes of cardiopulmonary resuscitation 1 . The authors provide impressive data supporting the conclusion that in their population failure to increase PetCO2 to levels exceeding 14 mmHg kPa after 20 minutes of attempted resuscitation served as a reliable guide for terminating unsuccessful cardiopulmonary resuscitation. The population studied however differed in some respects from the majority of earlier demographic reports that the authors cited with hospital survival 3 . More than 53 survived. The majority of instances of cardiac arrest reported by them was witnessed and as many as one-third of victims received bystander cardiopulmonary resuscitation - .
