Arterial pulse pressure (PP) respiratory variation is a good predictor of fluid responsiveness in ventilated patients. Recently, it has been shown that variation in PP may correlate with variation in pulse oximetry plethysmographic (POP) waveform amplitude, as they both depend on the stroke volume. We designed a prospective study to evaluate the correlation between respiratory arterial PP variation and POP waveform amplitude variations in ventilated patients and the influence of acute lung injury (ALI) in this relationship.
