Assessment of auto-titrating positive airways pressure in the management of treatment-related aerophagia.

INTERVENTION: Patients will be assigned to using an auto‐titrating positive airways pressure device overnight for 2 weeks. Auto‐titrating positive airways pressure devices treat obstructive sleep apnea by delivering pressurised air via a hose to a mask interface. It delivers the pressure by sensing when the airway closes and only increasing the pressure if necessary. This is a crossover study and there is no washout period between treatments. CONDITION: obstructive sleep apnea PRIMARY OUTCOME: The primary outcome measure is usage. Usage is the amount of time participants use the treatment device. SECONDARY OUTCOME: Visual Analogue Scale data to measure the presence and severity of abdominal pain/ discomfort Visual Analogue Scale data to measure the presence and severity of bloating. Visual Analogue Scale data to measure the presence and severity of flatulence INCLUSION CRITERIA: Patients who have reported symptoms of aerophagia whilst on continuous positive airways pressure therapy for obstructive sleep apnea.
