Details and patient eligibility

About

The purpose of this study is to analyze the relationship of the area under the curve (AUC) and/or the amplitude (Amp) of pulse oximetry plethysmographic waveform (POP) with partial pressure of end-tidal carbon dioxide (PETCO2) which could be used to reflect its quality in cardiopulmonary resuscitation (CPR), and then to determine the critical threshold of POP parameters in high quality CPR.
