Conclusions PAV is a feasible method for supporting ventilator-dependent patients and was well tolerated. It can improve the breathing pattern and reduce inspiratory effort. At the same degree of respiratory muscle unloading, PAV can be implemented at much lower peak inspiratory pressure than PSV. It can also apply proportional pressure support according to the patients’ ventilatory demand.

Proportional assist ventilation (PAV) a significant advance or a futile struggle between logic and practice?

[From  Thorax Online ]

Proportional assist ventilation is a promising addition to
other more conventional modes of mechanical
ventilation with the theoretical advantage of improving
patient-ventilator interaction. It may also be of use as a
diagnostic tool in the control of breathing in
mechanically ventilated patients.
