Brief summary
Thirty (30) research participants will undertake at-home Sonomat sleep studies, for 3 nights. Screening for sleep disordered breathing with preliminary STOP-Bang questionnaire, Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI) to take place prior to overnight testing. A subset of ten (10) will be referred for concomitant diagnostic PSG and Sonomat studies prior to the first at-home Sonomat recording, whilst breathing room air. This will take place within an outpatient technician-supervised sleep laboratory. Disease severity indices including respiratory function tests and a 6-minute walk test, will be obtained at baseline, 6 and 12 months. The three (3) questionnaires (STOP-Bang, ESS and PSQI), lung function tests and 6 minute walk test will be repeated at 6- and 12-months following sleep studies.
Interventions
The Sonomat is a mat-based, non-contact recording system that can be used in the laboratory or the home. This device measures OSA and breathing/body movements, but it can also detect other lung sounds typically heard via a stethescope such as crackles and wheeze.
Research participants will be invited to consent to either 3 nights at home sleep studies using the Sonomat, or 1 night in-hospital polysomnography (PSG) sleep study, plus concomitant Sonomat study, followed by 3 nights at home sleep

Participants will be followed up for 12 months following initial sleep investigations (Sonomat, and a sub-set of participants with additional polysomnography). Disease severity indices including respiratory function tests and a 6-minute walk test, will be obtained at baseline, 6 and 12 months. The three (3) questionnaires (STOP-Bang, ESS and PSQI), lung function tests and 6 minute walk test will be repeated at 6- and 12-months following sleep studies.
