HALOA: Cardiac Coherence With CPAP for Obstructive Sleep Apnea (HALOA)
Effect of Adding Cardiac Coherence to Continuous Positive Airway Pressure in Patients With Obstructive Sleep Apnea: A Multicenter Randomized Delayed-Start Controlled Study
This multicenter study will evaluate whether adding cardiac coherence breathing sessions to continuous positive airway pressure (CPAP) improves sleep quality in adults with newly diagnosed obstructive sleep apnea who are starting CPAP. Approximately 180 participants will be randomly assigned to one of two groups. Both groups will start treatment with the HALOA CPAP system. In one group, the cardiac coherence module will be activated at the start of treatment. In the other group, participants will use CPAP alone for 8 weeks before the module is activated.
Sleep quality will be assessed at study entry, at 8 weeks, and at 16 weeks using the Pittsburgh Sleep Quality Index. The primary comparison will assess the change in sleep quality from study entry to week 8 between the two groups. Secondary assessments will include daytime sleepiness, insomnia symptoms, anxiety and depression symptoms, treatment satisfaction, usability of the cardiac coherence module, CPAP use, and heart-rate variability when polysomnography recordings are available.

Gedetailleerde beschrijving
Obstructive sleep apnea is commonly treated with continuous positive airway pressure (CPAP). However, some patients have difficulty adhering to CPAP or experience persistent sleep-related symptoms. Cardiac coherence is a guided breathing practice intended to support relaxation and emotional regulation. The HALOA system combines CPAP treatment with a cardiac coherence module. This study will assess whether access to this module from the start of CPAP treatment improves subjective sleep quality compared with starting the module after an initial period of CPAP alone.
This is a prospective, multicenter, randomized, open-label, delayed-start controlled study. Approximately 180 adults with newly diagnosed obstructive sleep apnea and an indication for CPAP will be enrolled at 11 planned centers. Participants will be randomly assigned in equal numbers to one of two groups.
All participants will begin CPAP treatment using the HALOA system and will receive usual CPAP care. Participants in the immediate-intervention group will have the cardiac coherence module activated at study entry and will receive guidance on its use. Participants in the delayed-intervention group will use CPAP without cardiac coherence for the first 8 weeks. After the week 8 assessment, the module will be activated and participants will receive guidance on its use.
Study assessments will take place at baseline, week 8, and week 16. The primary outcome is the change in the global Pittsburgh Sleep Quality Index (PSQI) score from baseline to week 8, comparing the two randomized groups. The week 8 assessment provides the controlled comparison before participants in the delayed-intervention group begin cardiac coherence. Changes in PSQI from week 8 to week 16 in the delayed-intervention group will also be assessed to explore the effect after the module is introduced.
Secondary assessments will include daytime sleepiness using the Epworth Sleepiness Scale, insomnia symptoms using the Insomnia Severity Index, and anxiety and depression symptoms using the Hospital Anxiety and Depression Scale. Patient satisfaction will be assessed using the CSQ-8 and a study-specific questionnaire. Usability of the cardiac coherence module will be assessed using the System Usability Scale. CPAP adherence will be evaluated using device data, including hours of use and the proportion of participants meeting the protocol-defined adherence threshold. Heart-rate variability indices will be evaluated from polysomnography recordings when available.
Participants will be adults with obstructive sleep apnea diagnosed by polysomnography within the 3 months before inclusion and for whom CPAP treatment is indicated. The protocol lists recent CPAP or mandibular advancement device treatment, refusal of or contraindication to CPAP, inability to use the cardiac coherence device, and specified medical, psychiatric, or other circumstances among the non-inclusion criteria.

Experimenteel: Immediate cardiac coherence with CPAP
Participants will start HALOA CPAP at study inclusion. The cardiac coherence breathing module will be activated from the start of treatment, with guidance on its use. Participants will be assessed at baseline, week 8, and week 16. |
CPAP treatment using the HALOA system, initiated at study inclusion in both groups and provided as part of usual care. Guided cardiac coherence breathing sessions using the module integrated with the HALOA system. The module is activated at study inclusion in the experimental group and after the week 8 assessment in the active comparator group. |
|
Actieve vergelijker: Delayed cardiac coherence with CPAP
Participants will start HALOA CPAP at study inclusion and use it without the cardiac coherence module for 8 weeks. After the week 8 assessment, the module will be activated and guidance on its use provided. Participants will be assessed at baseline, week 8, and week 16. |
