Variable—Sustaining Inspiration

Easier for patients to alter their inspiratory volume by air stacking, which allows variation in speech and improves cough Less power and therefore batteries last longer [Pg.242]

In tracheostomized patients, pressure varies with changes in resistance and compliance assuring a certain volume delivery. [Pg.242]

There have been several inconclusive studies of patients with CRF comparing volume-targeted with pressure-targeted ventilation (9,10). Given equal efficacy, clinicians can feel comfortable to begin ventilation with the method of their choice. If patients fail to respond or are noncompliant, the other method should be tried. This is especially important for NIV where poor efficacy could lead to the need for a tracheostomy. [Pg.242]
