A comparison of carotid doppler ultrasonography and capnography in evaluating the efficacy of CPR.

Introduction And Purpose: The end-tidal carbon dioxide (ETCO2) measurement is accepted as the gold standard method for assessing cardiopulmonary resuscitation (CPR) efficacy. In recent studies, the use of Carotid Doppler Ultrasonography has become widespread in showing CPR efficacy. In the present study, the carotid blood flow measurement was compared with ETCO measurement and an evaluation was made of whether this method could be used as an alternative method to capnography in the assessment of CPR efficacy.
