Inpatient Portable Sleep Apnea Testing of Hospitalized Medical Patients for the Evaluation of Obstructive Sleep Apnea Prospectively Compared to Outpatient Laboratory-based Polysomnography

Hypothesis: Portable sleep testing of hospitalized medical inpatients suspected of having OSA is accurate in determining the need for positive airway pressure (PAP) therapy when compared to outpatient laboratory-based polysomnography.

• Hospitalized medical inpatients referred for suspected OSA will be tested with a portable sleep apnea testing device during hospitalization.
• These patients will then undergo an outpatient laboratory-based attended polysomnography after hospital discharge.
• Results of the inpatient portable sleep apnea test will be compared to the outpatient laboratory-based polysomnography in terms of diagnostic accuracy.
