WebStroke volume variations can effectively predict preload dependency in mechanically ventilated patients. Stroke volume can either be measured directly or estimated using the analysis of the arterial pressure waveform. Alternatively, pulse pressure variations can be calculated. However, these index are sensitive to tidal volume. WebJan 13, 2024 · Two clinical studies reported high PPV values (>12%) despite fluid unresponsiveness in the context of RV dysfunction ( 55, 56 ). However, in these studies, the V t was greater than 8 ml/kg, and one cannot exclude an attenuation of the phenomenon of RV afterload dependence during low V t ventilation.
