Abstract:
Objective:Pulse oximetry plethysmographic (POP) waveform to indicate the patient's perfusion status and the quality of resuscitation has been affirmed. The POP waveform is obtained by a non-invasive monitoring method, and its clinical feasibility during CPR is better than that of invasive monitoring technologies. This study aimed to analyze the three parameters derived from POP waveform: CPR quality index (CQI), perfusion index (PI), and chest compression fraction (CCF) in evaluating the CPR quality and ROSC possibility.Methods:A prospective descriptive study was conducted on 74 CPR patients who were divided into the ROSC group and non-ROSC group according to their resuscitation results. The clinical data were extracted from patient monitor, the distribution and changes of the three parameters during CPR were collected, and their value of evaluating resuscitation outcome were analyzed.Results:At the end stage of resuscitation, there were statistically significant differences in the three parameters between the two groups ( P<0.05). In addition, CQI was significantly more capable in evaluating the possibility of ROSC than PI and CCF ( P<0.05). Conclusions:CQI, PI and CCF derived from POP waveform can all be applied to evaluate CPR quality and ROSC possibility. CQI has higher prognosis value than PI and CCF.
