Frequently Asked Questions
What is a Home Sleep Test?
⚫ A Home Sleep Apnea Test (HSAT) is a screening test designed to diagnose or rule out Obstructive Sleep Apnea, one of the most common sleep disorders. ⚫ The HSAT device consists of mobile-phone sized unit, a belt worn across the chest, a painless finger cap to measure blood oxygen levels and a cannula to measure breathing.
Why should I have a Home Sleep Apnea Test?
A Home Sleep Apnea Test (HSAT) is a screening test for Obstructive Sleep Apnea, one of the most common sleep disorders. Obstructive Sleep Apnea can cause excessive daytime sleepiness and snoring, and is associated with obesity, heart disease, high blood pressure, stroke and diabetes. HSAT is usually recommended if you or your sleep partner have noticed you snoring particularly loud or excessively, or you experience daytime sleepiness.
How do I to prepare for a home sleep test?
You should try to limit caffeine and alcohol intake 24 hours before the test and try not to take a nap the day of the test. Also, if you are a caregiver for an infant or a bedridden individual, you should make alternate arrangements for the night of the test. Finally, go to bed at your normal time and get a good night’s sleep.
What time should I go to bed?
Stick to your normal bedtime routine so that you can get a full night’s sleep. You can turn on the device when you get into bed, even if you don’t fall asleep right away. If you get up in the night, it’s OK to leave the device on until you get back into bed.
What If I Wake Up During the Night?
If you need to get up in the middle of the night for any reason (use the bathroom, check on a child, get some water, etc.), please make sure to leave your device on and recording. Again, it is important that you wear the activated device all night regardless of what happens during that time. Once you wake up and get out of bed for the day, only then should you turn off the device and take it off to send it back for analysis
What happens after my home sleep test?
Your home sleep test records six separate physiological indicators from three sensors, including your blood oxygen saturation, heart rate, blood flow, snoring, body position and respiratory effort. Your doctor will interpret the results of your test and determine if you have sleep apnea. If you test positive for sleep apnea, your physician may recommend an in-center CPAP titration to administer CPAP therapy and find a treating pressure. Alternatively, you may be provided an auto-titrating CPAP device to use at home.
Will the sensor devices or tests hurt?
No. This is a painless and non-invasive (no needles) testing procedure. Sometimes, as a result of rubbing the skin or application of the electrodes, there is some mild skin irritation.
