Medical Definition of Stroke volume - MedicineNet
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. http://ht.edwards.com/resourcegallery/products/mininvasive/pdfs/stroke_volume_variationpdf.pdf#:~:text=Stroke%20volume%20variation%20is%20a%20naturally%20occurring%20phenomenon,pressure%20secondary%20to%20negative%20pressure%20ventilation%20%28spontaneously%20breathing%29. chuck ford carmel
