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. WebVelocity Time Integral (VTI, stroke distance) The formula Q = a · v states that flow (Q) is the product of area (a) of the cylinder and the velocity (v) of the fluid (i.e blood). The volume (V) that passes a specific segment is the …

Weba low central venous pressure is important, it is known that low stroke volume variation may be associated with increased blood loss. Therefore, we compared the effect on blood loss of 40 patients randomly assigned to a high stroke volume variation group (maintaining 10–20% of stroke volume variation) vs 38 patients in a control group WebStroke Volume. Stroke volume is the amount of blood ejected from the ventricle with each cardiac cycle. It can be readily calculated by subtracting the end-systolic volume from the …
