PAP Systems Internal Clinical Studies (ICS)

This is an open label, prospective, randomized cross over (or single arm) study designed to support the development of new accessories for PAP devices. This generic protocol provides a framework methodology for how these ongoing studies will be conducted. This protocol then is used in a number of smaller sub-studies, each of which will have their own sub-protocol outlining the exact specifics of the study.

The studies could be run face-to-face or remotely.

Participants are healthy volunteers who are ResMed employees. Recruitment will be done via emails. Participants will be explained the details of the trial and those who wish to take part will be invited to a selected site for the first study visit.

Visit 1: Participants will provide written informed consent. Participants will be shown the PAP systems and trial them for fit and comfort. Participants may be asked initial questions on their first thoughts on the PAP systems. If the participant and assessor are happy to proceed, the participants will use the loan PAP system for trial.

Visit 2: After trialing the PAP systems, participants will be asked to complete a questionnaire regarding the appeal, comfort, and usability of the PAP system(s). Depending on sub-study protocol, participants will then take the second PAP system home to test.

Visit 3: The participant will return the loan PAP system to the assessor. The participants' questionnaire responses will be reviewed. This concludes the participation in the study.
