Home Sleep Test

What is a Home Sleep Test (HST)?

A simple, reliable, cost effective sleep testing device that identifies patients for Obstructive Sleep Apnea (OSA).

The test is performed in the comfort of your own home. You will be instructed on how to use the device by a Sleep Technician. When you are ready to go to bed, simply put on the device, push a button and sleep until the next morning. In the morning, simply push the same button again and the test is complete. Return the device to the office the following day.

When the device is returned, the results are downloaded reviewed and interpreted by a Board Certified Sleep Physician. The results are them provided to your physician. If appropriate, the physician may order a CPAP Titration Study.

Is HST covered by insurance?

YES! Most insurances cover the HST. Many of them are not initially requiring authorization to get this test done. If a patient does not have insurance, low private pay rates are available.

What kind of equipment is used?

USD has chosen to use the Apnea Link Air.


A battery- powered user-friendly device. This device measures airflow through a nasal cannula along with oximetry and pulse via a finger probe. The Effort Belt with EasySense measures respiratory effort. The device contains a Start/Stop button and a recorder light to let you know it’s recording. The device features 3 lights that will turn green when all probes are connected correctly and red if they are not connected correctly. The device also has simple, easy-to-use component connectors.

How do I put on and use the Apnea Link Air?

Step 1: Attach Nasal Cannula

Place the nasal cannula under your nose, with the two small air tubes protruding slightly into your nostrils. Run the sensor tubing up and behind your ears so that the lead collar rests underneath your chin. Snug the sensor leads to prevent slipping. Then put a piece of tape on each side of the nose to make sure it doesn’t come off during the night.

Step 2- Attach Finger Pulse Sensor

Place this finger sensor over your index or middle finger, with the cable staying along the top of your finger and hand. Put tape on top of the cable to make sure it stays on during the night.

Step 3: Start Recording

Attach the device with the chest belt securely around your upper chest.
Press and hold the center POWER button for three seconds on the front of the device until the light turns green.

Once the green power light turns on, you will see one green light near each sensor attachment on the module. If all three lights turn on green, no other action is needed.
If any of the lights turn red, you will need to re-adjust the sensors and make sure the one on your finger is correctly on or the cable is securely connected.

If you wake up during the night to use the bathroom or have a snack, ITS OK, do not remove anything and do not press the center POWER button again. Let the device continue to record.

Step 4: Stop Recording

Press and hold the center button for three seconds, until the lights turns off. Then, you will see a light next to “Test Complete”. If the light is red, then you did not record the minimum six hours. Please call the office for instructions; you may be asked to repeat the study. If the “Test Complete” light is green, press and hold the center button for 1-2 seconds until the “Test Complete” light turns off. Remove all sensors and place the equipment back on the bag and bring it to our facility.
