Mar 21, 2000 · Proportional Pressure Support (PPS-) is a partial ventilatory support that overcomes patient respiratory system elastance (Ers) and resistance (Rrs) by applying pressure `proportional' to volume (volume assist, VA) and flow (flow assist, FA) respectively.The aim of this study was to evaluate its clinical use at the bedside in critically ill intubated patients affected by acute lung injury (ALI).

Dec 10, 2018 · Pressure support ventilation (PSV) is the most commonly used mode for the liberation process [2, 3], but presents several limitations. First, the optimal pressure support level for weaning varied among patients. Both over- and under-assistance may cause a diaphragm weakness .Cited by: 3

Mar 11, 2017 · In pressure support, the support is a fixed driving pressure. In PAV, the support is adaptive to keep work of breathing constant. In this mode, the magnitude of ventilator assistance (flow, volume or pressure) was neither predetermined nor constant but adjusted to the patient’s respiratory drive and mechanical obstacles to its output (i.e ...
