Fig. 5From: Correlation between end-tidal carbon dioxide and the degree of compression of heart cavities measured by transthoracic echocardiography during cardiopulmonary resuscitation for out-of-hospital cardiac arrestThe ROC curves for prediction of different EtCO2 levels by CImax. On the left, prediction of EtCO2 > 15 mmHg, in the middle prediction of EtCO2 > 20 mmHg and on the right prediction of EtCO2 > 25 mmHg. EtCO2—end-tidal carbon dioxide levelBack to article page
