Continuous positive airway pressure delivery interfaces for obstructive sleep apnoea.

Continuous positive airway pressure (CPAP) is the mainstay of therapy for moderate to severe obstructive sleep apnoea (OSA). However, compliance with CPAP has been less than ideal. There are many different CPAP interfaces now available for the treatment of OSA. The type of CPAP delivery interface is likely to influence a patient's acceptance of CPAP therapy and long term compliance.
