Intermittent positive pressure breathing (IPPB) is a respiratory therapy that is used to expand the lungs and induce hyperinflation (Laffont et al. 2008). Little is known about the effects of IPPB in SCI patients, and very little literature is published for patients with acute SCI. The limited studies that do exist examining IPPB in patients with quadriplegia, very few complications occur after treatment (Laffont et al. 2008).
In a pre-post study by Stiller et al. (1992), the effectiveness of intermittent positive pressure breathing on lung capacity was studied. The authors found that this style of mechanical ventilation significantly increased lung volume, as well as vital capacity (Stiller et al., 1992).
There is level 4 evidence (from one pre-post study; Stiller et al., 1992) that intermittent positive pressure breathing may increase lung volume as well as vital lung capacity in acute SCI individuals.
Intermittent positive pressure breathing can increase lung volume as well as vital lung capacity in acute SCI individuals.
