Key result
Photoplethysmographic pulse variation >9% identified patients with arterial pulse pressure variation >13% (AUC 0.85), serving as a noninvasive predictor of fluid responsiveness.
Why the study?
Can photoplethysmographic pulse variation predict fluid responsiveness similarly to arterial pulse pressure variation in mechanically ventilated patients?
Population
57 patients in the operating room and intensive care unit undergoing mechanical ventilation
Comparison

May support noninvasive fluid responsiveness assessment in ventilated patients; leaves open prospective outcome validation before practice change.
Observational (n=57)
Can photoplethysmographic pulse variation predict fluid responsiveness similarly to arterial pulse pressure variation in mechanically ventilated patients?
Effect estimate: AUC 0.85
Photoplethysmography can serve as a noninvasive predictor of fluid responsiveness in mechanically ventilated patients, correlating well with arterial pulse pressure variation.
Natalini et al. (2006) conducted an observational in Mechanical ventilation (n=57). Photoplethysmography vs. Arterial blood pressure waveform was evaluated on Identification of arterial pulse pressure variation >13% (AUC 0.85). Photoplethysmographic pulse variation >9% identified patients with arterial pulse pressure variation >13% (AUC 0.85), serving as a noninvasive predictor of fluid responsiveness.
