Obstructive Sleep Apnea, Sleep Disordered Breathing
Conditions
Brief summary
This investigation is designed to evaluate the performance (leak and comfort) as well as the participant's overall acceptance of the trial nasal mask amongst Obstructive Sleep Apnea (OSA) participants. An important factor in this investigation will be the testing of two different seal sizes on the participants (medium and large size). A total number of 12 participants who currently use nasal or nasal pillow masks will be recruited for the trial. Participants have been selected based on their anthropometric measurements collected in previous trials (CIA-103). Participants from previous NZ trials may be recruited into this trial with their consent. All the participants will be recruited from the Fisher & Paykel Healthcare Database of subjects with OSA (Ethics Reference NTY/08/06/064), Auckland District Health Board (ADHB) and New Zealand Respiratory and Sleep Institute (NZRSI). Participants will use the trial mask in home for a period of 7 ± 3 days and also 1 overnight polysomnography session at the Fisher & Paykel Healthcare sleep lab. Baseline data will be collected from the participant during the first visit, 7 days of CPAP usage data will be downloaded and stored for analysis. The participant will use the trial device on their usual Continuous or Auto Positive Airway Pressure (CPAP/APAP) setting and device for the duration of the trial.
