Our patients use a Philips Respironics G3 Night One Home Sleep Testing Unit. A staff member will instruct you how to use the home sleep apnea testing unit; it will loosely secure to your chest along with breathing, oxygen level, and heart rate monitors. Most patients will use an HST unit for two nights to ensure there is enough sleep data recorded for our doctors to make a diagnosis. Home sleep tests are used to diagnoses obstructive sleep apnea in adult patients.
1. Wear a sleeved shirt.
The night you take your home sleep test, be sure to wear a shirt with sleeves. The testing unit will wrap around your chest, and the strap can rub bare skin making it uncomfortable while sleeping.
2. Remove acrylic nails or nail polish.
Our home sleep test will include a pulse oximeter that will fit over your finger. This pulse ox has an infrared light that measures your oxygen saturation level; this is recorded throughout your test. The infrared light cannot measure the oxygen in your blood levels through nail polish or acrylic nails.
3. Band-Aids or tape can help with comfort.
The nasal cannula and the pulse oximetry will connect to the main unit. These tubes and wires can be uncomfortable and get pulled off during sleep if they are not adequately secured. We recommend taking a band-aid or tape to secure the pulse oximetry wire to the back of your hand, ideally leaving slack, just in case you need to move it to another finger throughout the night. After inserting the nasal cannula prongs down, we also recommend using the band-aid or tape to secure the tubing on each cheek. This can help prevent it from moving around too much and becoming uncomfortable.
4. Once everything is green, the device will go dark.
As you are connecting the device to the pulse oximetry, a nasal cannula, and the belt green lights will appear atop the unit. Once these lights have all turned green, they will go dark. This means that the device is ready to record your sleep for the night. The lights turn off so they will not bother you while you are sleeping. One way to know the machine is still on is that you can see the infrared light on the pulse oximetry.
5. After you wake up, let the device shut itself down.
Once you wake up in the morning and you remove the belt, the device will shut off on its own. It can take the device up to 30 minutes to shut down as it works to determine if the test is completed. There is nothing you need to do, just return it to the case for safe keeping until you are ready to go to sleep for the second night or for when you return it to the office.
