Abstract
The usefulness of continuous monitoring of central venous oxygen saturation (ScvO2) in comparison with the capnogram during cardiopulmonary resuscitation (CPR) was demonstrated in a cardiac arrest patient. ScvO2 and end-tidal carbon dioxide (ETCO2) decreased following cessation of chest compression or increased during recovery of systemic circulation. During the complete stasis of systemic circulation, when defibrillation was done, ScvO2 did not change, while ETCO2 gradually decreased. However the larger decrease in ScvO2 temporally occurred when chest compression was resumed. And also the ScvO2 monitoring had great advantage to detecting peripheral tissue oxygenation. ScvO2 seems to be no less accurate and reliable monitoring than the capnogram during CPR procedures. Since the capnogram is non-invasively and easily used in cardiac arrest patients, ScvO2 monitoring combined with the capnogram is a more preferable method for assessing the efficacy of ongoing CPR.
