Obstructive sleep apnea has become a fairly common disorder. It is believed that approximately up to 7% of the population experiences obstructive breathing disorders like OSA.
If left untreated, the condition can evolve into high blood pressure and heart diseases.
Luckily, when discovered and treated on time, sleep apnea can be managed and even treated completely. But, the problem lies in the fact that many people don’t even know they have sleep apnea. And even if they suspect, getting a test or polysomnography can be rather costly. That is why many seem to consider the home test option.
Therefore, in the following paragraphs, we’ll let you know everything about home sleep apnea tests, how they work, and what we recommend if you want to try the test yourself.
Home Sleep Apnea Test – Explained
What Is A Home Sleep Apnea Test?
The home sleep apnea test is used for the diagnosis of obstructive sleep apnea. The OSA home test is a convenient way to get a test and diagnosis in the comfort of your own home, which is rather convenient in the current times of coronavirus. Some people want to avoid going to the doctor to prevent getting infected, while others simply want to avoid the high costs of getting polysomnography.
The home sleep apnea test is conducted by you; there is no doctor or medical assistance or a sleep technician to administer the test. The test is conducted using one of the sleep apnea testing devices (portable breathing monitor kit), which you can get by consulting with your doctor or physician.More to know: Two Types of Sleep Apnea: Obstructive and Central
How Does One Perform The Home Sleep Apnea Test?
Because the home test is a simplified version of the in-lab test, one can easily perform the sleep apnea test on their own.
After consulting with your physician, you should be prescribed a portable breathing monitor kit, which you can take home. For the proper testing and test results, you should;
- Read the test instruction thoroughly
- Ensure that the breathing monitor kit is properly set up with the monitoring sensors
- Sleep using the home sleep test equipment for several nights (often 3 nights)
- Gather the data for your doctor’s assessment
- Return the portable breathing monitor device
- Wait for the doctor’s assessment and report
- Discuss the results and consider future steps in case the results indicate a sleep apnea diagnosis
Patients are often prescribed an at-home sleep apnea test in the following cases;
- They suspect to have OSA
- They have a significant comorbid medical disorder
- They have a comorbid sleep disorder
- They suspect to have nocturnal seizures, nocturnal arrhythmias, and hypoventilation
- They are on opiates, etc.
Note: After a patient performs a home sleep apnea test, and they are positive for OSA, they often get treatment or are prescribed for polysomnography. The home test is positive if it shows prolonged, sustained hypoxemia, central apneas, or mixed apneas. In such cases, polysomnography is required for a more accurate depiction of the condition and the required treatment options.
How To Prepare For A Home Sleep Apnea Test?
Once you’re prescribed a home sleep apnea test, you need to start to follow some rules to properly prepare for the test. To get the best and most accurate results, we recommend;
- Avoiding alcohol and caffeine – both of the substances can aggravate your sleep apnea and disrupt one’s sleep regardless of the condition. Caffeine will make you feel more awake and make it difficult for you to fall asleep. Alcohol, on the other hand, may help you fall asleep faster, but it will promote frequent awakenings throughout the night, as well as disrupt usually normal metabolic functions. If you do have to consume caffeine, try to do it before lunch. The same goes for alcohol, but we recommend you skip drinking for at least a few days, while the test lasts.
- Avoiding napping after 3 pm – even though naps can be a great way to compensate for the lack of sleep, they can also disrupt your sleep-wake cycle and promote nighttime wakefulness. So, during the period of the sleep apnea test, try to avoid napping after 3 pm, or avoid it completely until the test is done.
- Sleeping on the back and the sides – for the test to show accurate results, you need to try sleeping on your back and sides. Sleeping on the back may seem counterintuitive since this sleep position aggravates sleep apnea. Side sleeping as well can either cause sleep apnea or aggravate it. Because the purpose of the test is to not only see whether you have sleep apnea but also how bad it is, these sleeping positions can help get the most accurate depiction of your OSA status.
Advantages And Disadvantages of The Home OSA Test
Just like everything in like, the home sleep apnea test has a set of advantages and disadvantages. Before you decide this test is the best way for you to determine whether you have a sleep problem or not, make sure to consider the pros and cons of the home test;
- Convenience – the home test is more convenient than the lab tests, especially during the ongoing coronavirus pandemic when you want to stay away from hospitals and clinics as much as you can. Moreover, the test is convenient because you may sleep more normally than during the lab testing, since you’re at your own home, following a sleep routine that might show more accurate results.
- Less expensive – compared to the in-lab tests, the at-home test maybe even up to 20% less expensive. The at-home tests require less equipment, don’t require a doctor or physician assistance, and overall offer some DIY testing options, unlike the in-lab tests. In some cases, the at-home test is even covered by insurance.
- Fast results – unlike in-lab testing, the at-home test provides much faster results. The reason for that lies in the portable breathing monitor, which you take home and may start the monitoring that very night. In a few days, you can return the device and your doctor can immediately study the results and come up with a diagnosis or further testing options.
- Accessibility – not everyone lives near a hospital and a clinic. So, going for an in-lab sleeping test may be a difficult option to follow. That is why at-home testing is more accessible and more realistic for the majority of people. In some cases, the monitoring device can be even sent or returned by mail, so some patients don’t even have to go to the hospital or clinic.
Home Sleep Apnea Test Results – Explained
After you’re done with the home test, you’ll return the device to your doctor for the result analysis. The way the test results are analyzed are as follows;
- The doctor will use the Apnea-Hypopnea Index (AHI) to diagnose obstructive sleep apnea. AHI is a measurement scale used to identify the number of apneas (lapses of breath) occurring every hour of sleep. In people with mild sleep apnea, there are up to 5 apneas occurring every hour of sleep. However, in people with severe sleep apnea, there are between 25 and 30 apneas per hour of sleep. I these cases, further lab testing is required.
- The doctor will continue reviewing your oxygen levels. If the oxygen levels are lower than the average, chances are sleep apnea is the main cause. In such cases, further lab testing is required.
- The doctor will advise repeating the test in case the results are unclear or suspected to not be accurate. That is also recommended in case the symptoms continue but there is no sleep apnea diagnosis. Some doctors, in such cases, skip the home test and recommend an in-lab test right away.
