Effects of stroke volume variation, pulse pressure variation, and pleth variability index in predicting fluid responsiveness during different positive end expiratory pressure in prone position.
To investigate the effects of different positive end expiratory pressures (PEEP) on functional hemodynamic parameters in patients lying in prone position during operation under general anesthesia. ⋯ SVV,PPV and PVI can predict fluid responsiveness similarly under the PEEP levels of 0,5, and 10 mmHg. Their diagnostic thresholds increases with the PEEP and the diagnostic accuracies decrease with the PEEP. However, under the PEEP level of 15 mmHg, SVV, PPV, and PVI can not predict fluid responsiveness accurately.
