Maximizing Use of Continuous Positive Airway Pressure in Stroke Rehabilitation Patients With Obstructive Sleep Apnea

Experimental: CPAP intervention

Participants will receive 3 nights of auto-CPAP in order to identify those with OSA using flow resistance detected by the device. After 3 nights, those without apparent OSA or with central apnea, and those who simply do not tolerate CPAP will be excluded from the study. An intensive CPAP adherence protocol (iCAP) will be initiated, including collaborative care with rehabilitation nurses, the study's sleep technologist and overnight respiratory therapists. After the run-in period, the sleep technologist will meet at least twice weekly with CPAP-tolerant participants during their rehabilitation stay for further OSA education and encouragement with a target adherence of 4 hours per night. Participants diagnosed with OSA by the device and tolerant will continue CPAP therapy during rehabilitation and at home for a treatment period of 3 months. Adherence will be downloaded remotely from participant's machines to encourage adherence to treatment and troubleshoot any problems with the device.
