This article reviews the evidence to date examining whether adherence to positive airway pressure (PAP) therapy is affected by any device modifications to pressure delivery. To date there is no robust evidence from systematic reviews and meta-analyses indicating that any modification to standard fixed-pressure PAP makes a clinically significant difference to patient adherence to therapy. The main modifications are reviewed in this article and whether improving pressure could drive adherence, in turn improving patient outcomes, is discussed.
