A sleep study test is an overnight sleep test that records important sleep and physiological parameters like breathing and respiratory rate, oxygen levels, chest- and abdominal movement, heart rate, body movement and sleep onset. These parameters are used to calculate the Apnea–Hypopnea- Index (AHI). The AHI represents the number of apnea and hypopnea events per hour of sleep, and is used to determine the severity of Sleep Apnea.
On the day of the sleep study test, avoid caffeine after 12pm and try to minimise your alcohol intake. It is important for the sleep and health consultant to know what medication you are taking, even non-prescribed medication. Continue to take your prescribed medication on the night of the sleep study.
A qualified technician will meet you at our rooms, hospital or suitable location to successfully complete the procedure. You should dress in comfortable clothes that you can wear in bed.
Set up can take between 40 and 60 minutes. You will be required to complete an application form and a medical and sleep history questionnaire. Once all the paper work has been completed, set up will begin. Sensors will be placed on your body to record different parameters during sleep. You can go to bed at your normal bedtime, staying in bed for 6 to 10 hours.
The sleep and health consultant will schedule a suitable time and location for the return of the equipment the next morning. If you are in hospital, the equipment will be collected. The data will be downloaded and sent to a sleep specialist within our network of physicians or to a physician recommended by your referring healthcare practitioner.
The final recommendation report will be e-mailed or faxed to your healthcare practitioner immediately after the data has been interpreted. Consult with your doctor on the results and treatment options. Please SMS or email us for a copy of the report.
Your results are calculated by using the Apnea-Hypopnea-Index (AHI). It is calculated by the number of times a person’s breathing is interrupted for ten seconds or longer in an hour. A point is then allocated to distinguish between the severity levels:
|Normal Ranges||Mild OSA||Moderate OSA||Severe OSA|
|0 – 4 events per hour||5 – 14 events per hour||16 – 29 events per hour||30 and more events per hour|
