Brief summary
Continuous positive airway pressure (CPAP) is the treatment of choice for OSA. The CPAP pressure is delivered via a mask worn over the nose or the nose and mouth. If air leaks from the mouth or around the mask whilst being used, the treatment is not as effective and the patient may find it uncomfortable and not use it. We have two options to control mouth leaks , add a chinstrap to a nasal mask or change to a full face mask.We do not know which is the best option. The full face mask may leak more and is more expensive but the chin strap may not work. Also patients may find that one option is easier to use and more comfortable.
Interventions
Randomised crossover trial to compare three continuous positive airway pressure (CPAP) mask options. Nasal mask, using "best fit" from a variety of nasal masks with and without a chinstrap, and"best fit" from a variety of full face masks in control of CPAP pressure leak. All masks are fitted by experienced trained nurses. Patients wear each of the three interface options consecutively for a period of one month, in a predetermined random order.Patients are instructed to wear each of the three in

Data is collected for weeks 3 and 4 of use, to allow for a period of acclimatisation to each new set up.
