In-Hospital Portable Sleep Monitoring for the Evaluation of Obstructive Sleep Apnea (OSA)

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.

Inclusion Criteria:

- Hospitalized inpatients referred for evaluation of suspected obstructive sleep apnea

Exclusion Criteria:

• Patients admitted to surgical or obstetrics/gynecology services
• Patients with certain medical conditions (altered mental status not related to respiratory failure, septicemia, unstable psychiatric disorder, narcotic abuse and prior diagnosed sleep apnea)
• Patients with certain social histories (prisoners)
• Patients unable to use CPAP (facial deformity and traumatic facial injuries).
