However, reported cut-off values vary and the presence of a gray zone complicates clinical decision making. Measurement error, intrinsic to the calculation of pulse pressure variation (PPV) has not been studied but could contribute to this level of uncertainty. The purpose of this study w...
Pulse Pressure Variation (PPV) and Stroke Volume Variation (SVV) are dynamic fluid markers indicating the fluid responsiveness of a patient under general anesthesia for efficient fluid management over the course of Goal Directed Therapy (GDT).CALCULATION...
3. Using the cursor, find the systolic pressure value for the largest, or maximum, inspiratory waveform, then find the diastolic pressure. Take care to use the systolic and diastolic values on the same form. The difference in these two values...

Influence of increased intra-abdominal pressure on fluid responsiveness predicted by pulse pressure variation and stroke volume variation in a porcine model. OBJECTIVE: Dynamic variables of fluid responsiveness such as pulse pressure variation (PPV) and stroke volume variation (SVV) have been shown to ...
Both pulse pressure variation (PPV) and stroke volume variation (SVV), dynamic preload indices derived from the arterial waveform, are increasingly advocated as predictors of fluid responsiveness in mechanically ventilated patients. The aim of this study was to evaluate the accuracy of PPV and SVV ...
Pulse pressure variation (PPVAdequate volume resuscitation is very important for a favorable outcome of critically ill patients. Both over and under filling of intravascular volume could be deleterious. Static indices including central venous pressure, pulmonary capillary wedge pressure, left ventricular ...
Variations in stroke volume (SV) and pulse pressure (PP) occur as a result of interactions between the cardiovascular and respiratory systems. An alternative to SV optimisation is to minimise the variation in either SV or PP across the respiratory cycle. During inspiration (with positive pressure ...

OBJECTIVE: To compare the diagnostic accuracy of stroke volume variation (SVV) and pulse pressure variation (PPV) in studies that examined both parameters in the same patient population. METHODS: Literature search was conducted in PubMed, EMBASE, CINAHL, and Google Scholar. Receiver operator characte...
