Conditions
Interventions
Participants are assigned to either sleep position device (Night-Balance, Philips, The Netherlands) or CPAP (standard of care arm).

Eligibility
Inclusion criteria
Inclusion criteria: In order to be eligible to participate in this study, a subject must meet all of the following criteria: 1. Patients with central positional sleep apnoea are included in the study. 2. Apnoehypopneuindex = 5 AND = 30. 3. Patient age = 18. Central sleep apnoea is defined as: AHI = 5 with 50% or more of events occurring without any respiratory effort. And associated with symptoms of either excessive sleepiness or disrupted sleep. Positional sleep apnoea is defined as having a supine AHI=2x AHI non-supine with =10% and = 90% supine sleep
Exclusion criteria
Exclusion criteria: A potential subject who meets any of the following criteria will be excluded from participation in this study: 1. chronic respiratory insufficiency (paCO2 > 6kPA) 2. BMI = 30 3. Left sided valvular heart disease > mild 4. Patients with symptomatic heartfailure (AHA stadium C) 5. Night or rotating shift work 6. Active psychiatric disease 7. Seizure disorder 8. Medication use for sleeping disorders 9. Previous treatment with CPAP or sleep position device 10. Simultaneous other OSAS treatments 11. Pregnancy 12. Coexistent non-respiratory sleep disorders (e.g. insomnia, periodic limb movement disorder, narcolepsy) that would influence functional sleep assessment
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| AHI (apnea-hypopneas/hour) at 3 months and at 12 months will be compared to baseline. Succesfull treatment is defined as a reduction in AHI to < 5 events per hour at 3 months. Or either a 50% reduction in baseline AHI or a = 10 decrease in AHI combined with improvement in ESS (= 2 points). The proportion of patients reaching succesfull treatment in both treatment arms will be compared using Fisher’s exact test. Relative risk of succesfull treatment between both treatment arms will be calculated and 95% Confidence interval of the risk difference. | — |
