Is the pulse pressure variation a good predictor of fluid responsiveness in mechanically ventilated patients with low tidal volume?
A transversal and interventional study that included 30 critically ill patients with acute circulatory failure, sedated and mechanically ventilated with a tidal volume of 6 to 7 ml/kg. Mechanical ventilatory measurements including positive end-expiratory pressure plateau and peak pressures, static compliance and hemodynamic measurements including PPV, heart rate, mean systemic and pulmonary art...
متن کاملPulse pressure variation, stroke volume variation and dynamic arterial elastance
Which means that SVV (%) ≈ pulse pressure variation (PPV; %) for FloTracTM. With the present mathematical equation, it can be demonstrated that the SVV calculated by FloTracTM (SVVFT) is not infl uenced by Khi, which means that SVVFT calculation does not include eff ective arterial elastance (Ea). Th e originality of Garcia and colleagues’ fi nding is that they realized that when measuring PPV ...
متن کاملVentilator-induced pulse pressure variation in neonates.
During positive pressure ventilation, arterial pressure variations, like the pulse pressure variation (PPV), are observed in neonates. However, the frequency of the PPV does not always correspond with the respiratory rate. It is hypothesized that PPV is caused by cardiopulmonary interaction, but that this mismatch is related to the low respiratory rate/heart rate ratio. Therefore, the goal of t...
متن کاملStroke volume variation (SVV) and pulse pressure variation (PPV) as indicators of fluid responsiveness in sevoflurane anesthetized mechanically ventilated euvolemic dogs
Changes in stroke volume variation (SVV) and pulse pressure variation (PPV) in response to fluid infusion were experimentally evaluated during vecuronium infusion and sevoflurane anesthesia in 5 adult, mechanically ventilated, euvolemic, beagle dogs. Sequential increases in central venous pressure (CVP; 3-7[baseline], 8-12, 13-17, 18-22 and 23-27 mmHg) were produced by infusing lactated Ringer'...
متن کاملPulse pressure variation and prediction of fluid responsiveness in patients ventilated with low tidal volumes
OBJECTIVE To determine the utility of pulse pressure variation (ΔRESP PP) in predicting fluid responsiveness in patients ventilated with low tidal volumes (V T) and to investigate whether a lower ΔRESP PP cut-off value should be used when patients are ventilated with low tidal volumes. METHOD This cross-sectional observational study included 37 critically ill patients with acute circulatory f...
