Espanola sleep and
diagnostic centre

Sleep studies are performed in a diagnostic lab, within our family health team clinic. 

Patients are referred to the lab by their family physician, just as they would be referred for x-rays or bloodwork. Sleep studies occur in a clinical lab in the evening (between 8 PM and 7 AM). A technician (usually a Respiratory Technologist) is there for the entire shift to register the patient, hook up diagnostic equipment and monitor patients undergoing a sleep study. Generally speaking, the technician connects the recording and test equipment to the patient to monitor their sleep patterns. The equipment signals are displayed on diagnostic monitors located just outside the testing rooms and constantly monitored by the technician. Patients leave when testing is complete in the morning. Results of the tests/study are transcribed/sent to a medical specialist  who in turn interprets the study and (if needed) sets up an appointment with the patient for follow-up care. 

If you suspect you have a sleep disorder you should consult your physician.
