About this trial

The goal of this prospective cohort study is to study patients referred for sleep study by in-lab polysomnography in the Jordan University Hospital and the Jordan Hospital or with an at-home sleep study kit. The main aims are:

* To prospectively obtain demographic and clinical information of patients referred for a sleep study. * To determine the diagnostic value of facial discoloration as potential marker for obstructive sleep apnea to increase detection rate for the condition. * To establish a correlation between obstructive sleep apnea and vasovagal symptoms with resulting increased smoking tendency and study the effect of treatment on the disorders. * To determine the association between timing of appearance of obstructive sleep apnea symptoms and initiation of smoking.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Disqualifiers

Patients with prior diagnosis of obstructive sleep apnea by sleep study.

Trial population

The target population is patients above the age of 18 referred for sleep study at referred hospital. Patients who agree to participate in this study must sign the consent form.

    Device

    A machine that uses air pressure to keep breathing airways open while patients sleep.

  • Home sleep study device

    Diagnostic test

    Patient's brainwaves are recorded overnight to diagnose sleep disorder.
