Evaluation of Obstructive Sleep Apnea (OSA) Using Portable Sleep Testing (PST) Devices on an Inpatient Stroke Unit (OSA Trial)

The purpose of this study is to evaluate the feasibility of testing patients for OSA within the inpatient setting. As part of this program, the investigators are proposing early access to a sleep apnea treatment plan, potentially lowering the risk for future stroke symptoms, and preventing lost to follow up of patients for treatment since sleep disordered breathing is primarily considered a disorder that is managed in an outpatient setting. Hypothesis: Early identification of sleep apnea as a modifiable stroke risk factor (SRF) for acute ischemic stroke (AIS) and transient ischemic attack (TIA) patients using the STOP BANG questionnaire and portable sleep testing (PST) during inpatient hospitalization, will allow early identification of patients at risk for sleep disordered breathing, early diagnosis of sleep apnea, and earlier prescribed treatment prior to discharge.
