Abstract 13379: The Prognostic Value of Pulse Oximetry Plethysmographic Waveform During CPR
Introduction: A facile, early predictor of the outcome of resuscitation is needed. Pulse oximetry, which noninvasively detects the blood flow of peripheral tissue, has achieved widespread clinical use. We noticed that the better the quality of CPR was, the better the appearance of pulse oximetry plethysmographic waveform (POP) was. Hypothesis: We assessed the hypothesis that the amplitude of POP (Amp) and the area under the curve of POP (AUC) could be utilised as a tool to predict the outcome of resuscitation.
Methods: 617 cardiac arrest patients from 14 hospital in 10 cities were enrolled in the study and retrospectively assigned to two groups: ROSC group and non-ROSC group. Estimation of prognosis of cardiac arrested patients through the analysis of change of POP parameters during CPR.
Results: POP parameters in chest compressions stage [Amp (111.0 (66.0,210.5) vs 41.0 (23.0,119.8)) PVA, AUC (3243.5±30.8 vs 2334.0 (1827.0,3229.0)) PVPG (Figure 1)] and PETCO2 [(23.1±4.0 vs 13.0(8.0,23.0)) mmHg (Figure 2)] were statistically different between ROSC group and non-ROSC group (P < 0.01). Cut-off values for ROSC in CPR patients were shown in Table 1. Conclusions: In conclusion, POP parameters could help predict the prognosis of the patients during CPR. The prognostic value of POP parameters was non inferiority to PETCO2, and this method was noninvasive, safe, economy.
