Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will use an approved loan CPAP device, with an external module to collect acoustic signals from the tube and mask, for 7 nights with their normal mask and therapy settings in the home environment. Standard therapy involves wearing a CPAP mask with pressure applied, as prescribed by a physician, for duration of sleep cycle to treat sleep apnoea. Participants will complete a short diary entry each morning documenting bedroom and sleep set-up.

The prototype external module contains microphones which are coupled to the air path and record the sound in the tube whilst therapy is on. It is attached to the CPAP device between the CPAP device outlet and the patient tube, and has an ISO taper connector to enable connection of the patient's tube and attachment to the CPAP device outlet.
