The Recovery in Stroke Using PAP Study

Other illness

• Inability to provide their own informed consent. To enhance the generalizability of our study, all stroke severity will be included. However, we will exclude patients who cannot provide their own consent. This is because patients will need to participate actively in the protocol with a behavioral intervention. An assessment of the patient's competence to provide consent will be made based on published recommendations.

Lab values

• Suspected sleep disorder other than OSA (e.g., narcolepsy) (because such patients should be referred for a formal PSG in a sleep laboratory);

Other

• Past use of prescribed PAP for OSA;
• Life expectancy is less than 6 months (e.g., hospice patients);
• Patients who require mechanical ventilation (because such patients could not participate in the intervention protocol);
• Non-English language patients (because the intervention strategy involves forming a relationship between the patient and research staff);
• Central sleep apnea with \> 50% of respiratory events classified as central apnea;
• Resting oxygen saturation \< 90%.

• Having an acute ischemic stroke with brain imaging within 48 hours of symptoms onset;
• Being within 5 days of neurologic symptoms onset;
• Moderate (15 =\< overall AHI \< 30) /severe (overall AHI \>= 30) OSA, thus with an obstructive apnea-hypopnea index AHI \>= 15.
