Discuss sleep complaints and symptoms with your doctor.

If a sleep disorder is suspected, your doctor will refer you to a sleep specialist for proper evaluation.

In many cases, an overnight diagnostic sleep tests (known as a polysomnogram or PSG) will be used to determine the course of action and treatments.

A simple test uses typically 1 or 2 channels of information, usually oxygen saturation via pulse oximetry, and airflow by using a nasal canulla.

Lab titration procedures for the CPAP treatment is typically not performed as trained sleep technicians are only present during the preparation and instruction stage of the study, and do not usually stay for the full course of the test.

Polysomnography involves recording at least 7 channels of information: brain wave information, eye movements, ECG, abdominal and chest efforts, oxygen saturation via pulse oximetry, airflow, and body position during the full course of the test.

Sleep technicians are present during the PSG. They are able to titrate the CPAP treatment, consult with the attending foctor during the test, and intervene during the test if required.
