To properly diagnose sleep apnea, a patient must undergo a polysomnography (PSG), also known as a sleep study. This is usually done in a sleep lab, requiring the patient to spend the night at the facility while the PSG equipment records their physiological data. However, depending on the patient’s symptoms and other health related issues, an at-home sleep study may be an option.
Home sleep studies are convenient, and with the right diagnostic equipment, they can also be very accurate. Because home sleep testing is used strictly for diagnosing sleep apnea, it requires far less equipment than an in-lab study.
Sleep testing kits include a small nasal cannula to measure airflow, a belt worn around the upper chest to measure respiratory effort, and a finger clip to measure oxygen saturation in the blood. Depending on the manufacturer, certain kits may also come with sensors that are placed on the chest and abdomen before going to bed. Diagnostic kits track pauses in your breathing, the amount of effort it takes for you to breathe, the depth of your breathing, and your oxygen levels during sleep.
At Owens, our local sleep specialists offer one-on-one instruction. This provides patients with an opportunity to get fitted and ask questions about anything they don’t understand before testing begins.
