Brief Summary:
The present study is a prospective, single cohort study involving patients on narcotic medications, undergoing overnight sleep studies in the clinical sleep laboratory. The main hypothesis for the study is that the the frequency of sleep respiratory events (including central apneas) identified by a home sleep apnea test (HSAT) device (WatchPAT200U (wp200U) with centrals; Itamar Medical Ltd.) will significantly correlate with in-lab polysomnography (gold standard).

Arm Intervention/treatment
Experimental: WatchPAT 200 and In-Lab Study
Patients who are referred to the sleep center for an overnight study that are narcotic users will be offered to the opportunity to participate in the study. Patients who fulfill the inclusion exclusion criteria and have given informed consent will undergo a standard in-lab polysomnography while simultaneously wearing the WatchPAT200 device.
Diagnostic Test: WatchPAT 200
The WatchPAT200 device has been approved by the Food and Drug Administration (FDA) for testing sleep related disorders in patients ages 17 and older. They are widely used with thousands of studies performed in the United States to validate the devices accuracy and efficacy. It is also routinely used in many other countries. The devices are not currently being used for patients who are currently taking narcotic medications at Kaiser Permanente. Therefore, we are asking patients to simultaneously wear this device during an in-lab study, so we can test how effective and accurate the WatchPAT 200 is in diagnosing sleep breathing disorders in patients on narcotic medications.

Primary Outcome Measures :
  1. Accuracy of Central Sleep Apnea Events [ Time Frame: 1 year ]
    Compare the efficacy of the WatchPAT200 in detecting narcotic based central respiratory events to the manual scoring of the in-lab polysomnography that serves as a "gold standard".

  2. Accuracy of Other Various Sleep Metrics [ Time Frame: 1 year ]
    Compare the efficacy of the WatchPAT200 in detecting narcotic based oxygen, body position, and sleep-wake events to the in-lab polysomnography.
