Sleep apnea is a common sleep disorder that affects between two to nine per cent of all adults. A CPAP (Continuous Positive Airway Pressure) machine is a primary mode of treatment for this condition. Before starting CPAP therapy, a sleep study is often required to diagnose sleep apnea and rule out other conditions. This can be done at home or in a sleep lab. An at-home sleep study is a simplified breathing monitor that tracks your breathing, oxygen levels, and breathing effort. It is a cost-effective way to assess whether you are having trouble breathing during sleep.

Home sleep studies are cost-effective, simple, and can be self-administered
Home sleep studies are a cost-effective, simple, and self-administrable way to gain insight into your sleep health. They are especially useful if you are experiencing symptoms of sleep apnea, such as frequent morning headaches, excessive snoring, or daytime sleepiness.
Home sleep studies are a fraction of the cost of in-lab sleep studies and are often covered by insurance. They eliminate the need for multiple visits to a sleep lab, saving you time and money. The comfort of your own surroundings can also mean a more accurate reading of your sleep patterns, as you are likely to achieve a deeper sleep than in an unfamiliar lab environment.
The test itself is simple and non-invasive. It typically involves a simplified breathing monitor that tracks your breathing, oxygen levels, and breathing effort. Soft electrodes are placed on your skin, usually on the chest, and a nasal cannula is used to measure airflow. The sensors are hooked up to a small, lightweight device that records the data. The entire setup is easy to use and can be self-administered.
After just one night of sleep in your own bed, a home sleep study can provide valuable information about your sleep patterns and help determine if CPAP therapy is right for you. A physician will review the test records and, if necessary, work with other providers to coordinate your care. If symptoms persist or the results are inconclusive, your physician may recommend a follow-up sleep study in a lab for a more comprehensive assessment.

They monitor sleep patterns, including sleep time, sleep architecture, and central sleep apnea
At-home sleep studies are a simplified way to monitor sleep patterns and identify potential breathing issues associated with sleep apnea. While they do not capture the comprehensive data of an overnight sleep study at a dedicated sleep centre, they are a cost-effective option for individuals experiencing possible symptoms of sleep apnea.
Sleep apnea is a chronic sleep disorder characterised by interruptions in breathing during sleep. Obstructive sleep apnea (OSA) occurs when the airways relax and narrow, or even close completely, resulting in a brief cessation of breathing. This can happen hundreds of times a night, leading to a lack of oxygen and an increased risk of various health conditions. Central sleep apnea is another type, which is treated with adaptive servo-ventilation (ASV) that monitors and adjusts breathing patterns.
At-home sleep tests primarily focus on monitoring breathing patterns to detect sleep apnea. The test kit includes sensors that measure oxygen levels, as well as a mask with tubes inserted into the nostrils, similar to an oxygen mask. Additional sensors are placed on the abdomen and chest to track the rise and fall of the chest during breathing. These sensors provide data on breathing effort, pauses, and the depth of breaths. This data helps identify any breathing abnormalities associated with sleep apnea.
While at-home sleep tests do not directly analyse sleep architecture or sleep time, they offer insights into potential disruptions caused by sleep apnea. Sleep architecture refers to the various stages of sleep, including light and deep sleep, which can be affected by sleep apnea. By monitoring breathing patterns, the test can indirectly provide information about sleep quality and disruptions.
For individuals who want a more comprehensive analysis of their sleep patterns and sleep architecture, an overnight sleep study at a dedicated sleep centre is recommended. These in-lab studies are conducted by sleep technologists and capture a broader range of signals, including brainwaves, muscle tone, and leg movements. This additional data allows for a more nuanced understanding of sleep patterns and any potential disruptions.

They can be used to diagnose insomnia, sleep apnea, and other sleep disorders
At-home sleep studies are an easy and cost-effective way to diagnose insomnia, sleep apnea, and other sleep disorders. They are simplified breathing monitors that track your breathing, oxygen levels, and breathing effort. They can be used to determine whether you are having trouble breathing, and if you are experiencing insomnia or sleep apnea as a result.
Sleep apnea is typically characterised by frequent headaches upon waking, loud snoring, and excessive daytime sleepiness. An at-home sleep study can provide insight into your sleep health and determine whether you are experiencing sleep apnea. The test involves wearing a small probe over your finger that measures oxygen levels, and inserting a nasal cannula with tubes into your nostrils to measure airflow. Other sensors may be placed on your abdomen and chest to measure breathing, and soft electrodes may be placed on your skin to record brain and muscle activity.
The data from the at-home sleep study is then sent to a sleep technologist, who reviews the results and sends them to your physician. They will determine whether you are experiencing insomnia, sleep apnea, or another sleep disorder. If symptoms persist or the results are inconclusive, your physician may recommend an in-lab or overnight sleep study for a more comprehensive analysis. This is particularly true if you have certain heart, breathing, or neuromuscular problems, as these require a more thorough assessment of sleep issues.
At-home sleep studies are a convenient and accessible way to gain insight into your sleep health and diagnose potential sleep disorders. They are a good first step towards understanding and addressing any sleep issues you may be experiencing.

They are easy to use and involve a collection of sensors to track body functions during sleep
At-home sleep studies are easy to use and can provide valuable insights into your sleep health. They are designed to be simple and user-friendly, allowing you to collect data on your sleep patterns and body functions from the comfort of your own home.
The process typically involves a collection of sensors that track various body functions during sleep. These sensors are non-invasive and can be easily set up before you go to bed. The sensors may include:
- Soft electrodes that conform to your skin, often placed on the chest, scalp, eyelids, or chin.
- A nasal cannula or a device similar to an oxygen mask to measure airflow.
- A wrist sensor, pulse oximeter, or chest sensor to monitor heart rate and blood oxygen levels.
- Sensors to detect breathing patterns, sleep stages, body position, and sleep architecture.
All of these sensors are connected to a small recording device, about the size of a smartphone, which collects the data throughout the night. The data collected includes information on your breathing patterns, oxygen levels, heart rate, body movements, sleep cycles, and overall sleep quality.
The convenience and familiarity of your home environment during an at-home sleep study can promote a deeper and more natural sleep, potentially leading to more accurate results compared to a lab setting. However, it is important to note that at-home sleep studies may not capture all the data of an overnight sleep study at a sleep center, as they usually involve fewer sensors.

They are approved by the American Academy of Sleep Medicine and can be followed up with a sleep lab study if required
At-home sleep tests are approved by the American Academy of Sleep Medicine. They are a simplified version of the polysomnography (PSG) test, which is the gold standard for diagnosing sleep disorders. The at-home test is a cost-effective way to determine whether you are having trouble breathing. It involves a breathing monitor that tracks your breathing, oxygen levels, and breathing effort. The test is usually done for one night in the comfort of your own home, which can mean a more accurate reading of how you actually sleep.
After the test, a sleep technologist will review the results, which are then sent to your physician. If the results are inconclusive or indicate a condition other than or more severe than OSA, your provider may recommend an overnight sleep study at a sleep lab as a follow-up. An in-lab sleep study will be far more comprehensive than a home sleep study as it captures many more signals, including brainwaves, muscle tone, and leg movements. It can also measure neurological activity in your brain related to your breathing and sleep.
In-lab sleep studies are usually recommended for people with certain heart, breathing, or neuromuscular problems. They are also useful for people experiencing homelessness or living in a nursing home, as it can be difficult to perform an at-home titration in these situations. If you are already using a CPAP machine and suspect that the airflow pressure is too high or too low, you may also be asked to undergo an in-lab CPAP titration sleep study.
