Home sleep apnea test

home sleep test · home sleep apnea test · HSAT · overnight breathing monitor · snoring test at home

You take a small device home and sleep with it for one night. It records your breathing, oxygen, and pulse.

For loud snoring, pauses in breathing during sleep, and strong daytime sleepiness.

⏱ Duration: one night at home; results usually come in a few days

Be sure to tell your doctor

How to prepare

  • Evening. No alcohol or sleeping pills, unless your doctor allowed them. Go to bed at your usual time.
  • Fingers. Remove polish from the nail where the sensor will go.
  • The device. The nurse will show you how to put on the sensors. Ask to write it down or take photos.

What to bring

  • Your referral
  • A list of your medicines
  • A bag to return the device

How it goes

  1. At the clinic, you are shown the device and how to put it on
  2. In the evening before bed, you put a belt with sensors around your chest
  3. A thin tube goes under your nose, and an oxygen sensor on your finger
  4. You turn on the device and sleep as usual
  5. In the morning, you take off the sensors and turn off the device
  6. You return the device to the clinic the same day

What you'll feel

  • It does not hurt
  • The first few minutes feel strange, but most people fall asleep fine
  • The tube under your nose may bother you

Afterwards

  • Reading the results usually takes a few days
  • Take the results to your doctor. They will explain them and suggest treatment
  • If a sensor came off at night, say so when you return the device

Common questions

What if I slept badly?

A few hours of sleep is usually enough. If there is too little recording, the test may be repeated.

How is this different from a sleep lab?

At home there are fewer sensors and you sleep in your own bed. For some people, the doctor will still order a sleep lab study.
