This article compares volume-assured pressure support with a more carefully controlled period of volume ventilation. The results show reductions in the work of breathing and pressure-time product with volume-assured pressure support. Practical aspects of setting and adjusting volume-assured pressure support are also discussed.

This paper is a lung model study, but nicely reviews the pressure, volume, and flow waveforms provided by pressure augmentation.

Chest 1992, 102:1225-1234. This paper is the initial description of volume-assured pressure support. Results show significant reductions in the work of breathing and intrinsic positive end-expiratory pressure.

Intensive Care Med 1997, 23:975-981. This small study is one of the few that has been accomplished using this new mode. Subgroup analyses suggest some advantages of pressure-regulated volume control.

This paper shows that pressure-regulated volume control is in fact simply pressure-limited, time-cycled ventilation. In a short period of ventilation, the authors showed no differences between pressure-control ventilation and pressure-regulated volume control. The possibility that pressure-regulated volume control provides some advantage over time remains to be elucidated.

It also shows nicely the positive effects of automatic tube compensation on expiratory-flow resistance.
