Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
STUDY ARMS:

CPAP + (optimal level of humidity)

STAGE 1:
Participants will be randomised to 2 nights of full sleep study. (one night on each of the study arms)

Outcome measures:
Sleep quality (measured once after each nightime study)


STAGE 2:
After completion of stage 1 of the study particpants will be re-randomised to one of the two study arrms for three weeks at home on this arm. After completion of this 3 weeks particpants will be swapped to the alternate arm.


Outcome measures:
Compliance (recorded at the end of each 3-week arm)

Summary
Brief summary
The primary purpose of the study is to ascertain if delivering higher levels of humidity to patients undergoing CPAP treatment for Obstructive Sleep Apnea will result in greater comfort; better sleep quality and increased compliance with treatment. Our hypothesis is that supports this theory.

There are two STUDY ARMS:
CPAP + (conventional heated humidification)
CPAP + (optimal level of humidity)

STAGE 1:
Participants will be randomised to 2 nights of full sleep study. (one night on each of the study arms)

Outcome measures:
Sleep quality (measured once after each nightime study)


STAGE 2:
After completion of stage 1 of the study particpants will be re-randomised to one of the two study arrms for three weeks at home on this arm. After completion of this 3 weeks particpants will be swapped to the alternate arm.


Outcome measures:
Compliance (recorded at the end of each 3-week arm)
Subjective symptom score; relating to comfort (recorded at the end of each 3-week arm)
