Proportional Assist Ventilation vs Pressure Support Ventilation

In this study, we want to compare two different kinds of artificial ventilation to see if
one encourages faster weaning from breathing support and if one provides better sleep
quality. These artificial ventilation types are:

1. Pressure support ventilation; the standard ventilation that we use for the patients in
the Respiratory Acute Care Unit. Pressure support ventilation ventilators use constant
air pressure to assist patients with their breathing.

2. Proportional assist ventilation; a newer way of helping people with their breathing.
The air pressure provided by proportional assist ventilation ventilators varies with
the size of the breath that a person takes.
