The Critical Threshold of Pulse Oximetry Plethysmographic Waveform Parameters in High Quality CPR

November 26, 2018 updated by: Peking Union Medical College Hospital
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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
the cut-off value of POP parameters in High Quality CPR
Time Frame: one year
Describe the the cut-off value of POP parameters in High Quality CPR. Receiver operating curve analysis was performed to evaluate the accuracy in predicting return of spontaneous circulation (ROSC).
one year
Compare different predictors
Time Frame: one year
Area under curve (AUC) between potential predictors was compared by using a nonparametric test, and the optimal cutoff point was determined by estimating the Youden's index.
one year
