Proportional Assist Ventilation: Back to the Future?

Does the addition of non‐invasive ventilation during pulmonary rehabilitation in patients with chronic obstructive pulmonary disease augment patient outcome in exercise tolerance? A literature review

“…PAV is intended to supply pressure support proportional to patient effort. The fl ow assist setting is designed to off-load the resistive component of breathing and the volume assist the elastic component (Appendini, 2003). Patients with more severe airway impairment will suffer from a greater degree of dynamic hyperinfl ation and, subsequently, a greater PEEPi (elastic component).…”
