Continuous positive airway pressure (CPAP) therapy improves quality of life for obstructive sleep apnoea (OSA) patients compared to placebo. However, patients prefer oral appliances over CPAP, despite CPAP
Area of Science:
- Sleep Medicine
- Respiratory Medicine
- Clinical Trials
Background:
- Obstructive sleep apnoea (OSA) involves airway narrowing during sleep, leading to apnoea, hypoxia, and fragmented sleep.
- Continuous positive airway pressure (CPAP) is a primary nocturnal treatment for OSA symptoms.
- Clinical trials have assessed the efficacy of nasal CPAP for OSA treatment.
Purpose of the Study:
- To review the effects of CPAP in treating adult obstructive sleep apnoea.
Main Methods:
- Searched Medline, Embase, and Cinahl databases (1966-1996).
- Included randomized trials comparing nocturnal CPAP with placebo or other treatments in adults with an apnoea/hypopnoea index > 5/hour.
- Assessed trial quality and extracted data independently; contacted authors for missing information.
Main Results:
- Seven trials (177 participants) showed CPAP improved quality of life and depression measures compared to placebo.
- CPAP significantly improved apnoea/hypopnoea index and oxygen saturation versus oral appliances.
- Patients preferred CPAP over placebo but strongly preferred oral appliances over CPAP.
Conclusions:
- CPAP is more effective than placebo for improving some quality of life measures in OSA.
- CPAP demonstrates greater efficacy than oral appliances in addressing respiratory disturbances.
- Patient preference favors oral appliances over CPAP, while CPAP is preferred over placebo.
