Sleep Lab

The clinic is equipped with state of the art equipment, reception area, comfortable bedrooms and a wheelchair accessible washroom and shower facility.

Tests vary from simple screening to identifying whether patients require oxygen at night, to complete respiratory polysomnographic studies to assist in the assessment and management of sleep disorders.

Pulmonary function and pulmonary exercise testing is offered to assess lung disease type and severity. Pulmonary function tests (breathing tests) assess lung capacity, lung volumes and the ability of the lungs to move oxygen from the lungs to the blood under normal resting conditions. Pulmonary exercise tests monitor the ability of the lungs to function and move oxygen into the bloodstream when the body is at work (exercise).

Tests are interpreted by a respirologist and the results sent to the patient’s referring physician.
