Sleep Apnea: How Do Imaging Rings Work?

how does sleep image ring work

Sleep is a complex and dynamic process that affects how we function, and a chronic lack of sleep or poor-quality sleep can increase the risk of health problems. Factors that influence sleep needs include medical conditions, medications, stress, sleep environment, age, and what we eat and drink. Research has shown that guided imagery can be an effective way to improve sleep quality and manage pain. This technique, also known as visualisation or guided meditation, involves imagining peaceful settings and can be combined with calming music or sounds from nature. Visual meditation helps people focus their thoughts on a specific object or image, promoting a calm state through relaxation and mindfulness.

SleepImage Ring: Comfort and ease of use

The SleepImage Ring is a comfortable and easy-to-use device for those seeking a sleep test that is unlikely to interfere with their sleep. The ring is slipped onto the finger before bedtime and paired with the SleepImage app. It is a low-profile device that can be worn on any finger on the left hand, with the thumb or index finger being the recommended placement. It is important to achieve a snug fit without causing discomfort. The ring is charged via a USB port, which allows for multi-night testing without the need for a new device or additional consumables. The SleepImage Ring is also easy to clean and maintain, ensuring that it can be used multiple times without any issues.

The ring is a convenient alternative to traditional sleep studies, as it allows individuals to perform the test in the comfort of their own beds. This is especially beneficial for those who prefer to assess their sleep health at home rather than consulting a doctor for a prescription medical device. The SleepImage Ring is also a good option for those who already use a CPAP machine, as it can be easily used alongside the device. This allows individuals to gather data during their treatment, providing valuable insights into the effectiveness of their treatment plan.

The SleepImage Ring collects physiological data during sleep, including oxygen levels and heart rate. It measures six data channels, including sleep states (NREM vs. REM), sleep stages (stable vs. unstable NREM), and objective sleep quality using the FDA-cleared Sleep Quality Index (SQI). The data collected by the ring is then uploaded to a secure clinical portal, where it is analysed and presented for evaluation and diagnosis. This data helps doctors evaluate symptoms of sleep apnea and insomnia, as well as differentiate between obstructive sleep apnea (OSA) and central sleep apnea (CSA).

The SleepImage Ring has been cleared by the FDA for use in both children and adults and is only available for purchase by healthcare providers. It is a prescription medical device that is sold to licensed health care professionals, who then provide it to their patients. The cost of renting the device will vary depending on the physician and insurance provider, but it is generally less expensive than an in-person sleep study at a sleep centre.

How the ring collects data

The SleepImage Ring is a small, sleek device that collects physiological data during sleep. It is worn on the finger, with the thumb or index finger being the recommended placement. The ring is easy to use and does not require many components, making it suitable for at-home sleep testing. It is FDA-approved to diagnose sleep disorders like sleep apnea.

The ring collects data by measuring six data channels: wake versus sleep, sleep states (NREM vs. REM), sleep stages (stable vs. unstable NREM), objective sleep quality, pulse rate, and oxygen saturation. These measurements provide doctors with data that can be used to evaluate symptoms of sleep apnea and insomnia and to diagnose sleep apnea, including differentiating between obstructive sleep apnea (OSA) and central sleep apnea (CSA). The ring uses a technology called cardiopolmonary coupling (CPC) to determine sleep vitals. It calculates the coherence between heart/pulse rate variability and respiratory excursion, derived from a single-lead electrocardiogram (ECG) or photoplethysmogram (PPG) to generate distinct CPC patterns.

The SleepImage Ring is particularly beneficial for those who already use a CPAP machine, as it can be used simultaneously with the device to gather data on the effectiveness of the treatment plan. It is also a good choice for those who prefer to assess their sleep at home rather than in a sleep lab or clinic. The ring is comfortable and easy to use, simply slipping onto the finger before bed and pairing with the SleepImage app.

After wearing the ring during sleep, the data is uploaded to a doctor's secure clinical portal in the cloud, where it is analyzed and presented for evaluation and diagnosis. The SleepImage System Output is based on collecting signals controlled by the autonomic nervous system during sleep, and it provides comparable output to a polysomnography (PSG) test for diagnosing sleep apnea. The test is only available for purchase by healthcare providers, who can then prescribe it to their patients.

FDA clearance and prescription

The SleepImage Ring is a prescription medical device used for diagnosing sleep disordered breathing and requires a medical professional to prescribe the test. It is cleared by the U.S. Food and Drug Administration (FDA) for the diagnosis and management of sleep disordered breathing. It is considered Software as a Medical Device (SaMD) by the FDA, which is defined as "software intended to be used for one or more medical purposes...without being part of a hardware medical device." The SleepImage software is most commonly used with the SleepImage Ring as the hardware device, but it is compatible with other hardware devices.

The SleepImage Ring is an excellent choice for those seeking a sleep apnea test that is unlikely to interfere with their sleep. The ring is easier to use than most other types of at-home tests and has been cleared for both children and adults by the FDA. The SleepImage mobile app makes it easy to see whether the test is working, and the USB charging port ensures that multi-night testing can be completed without the need for a new device. The SleepImage Ring is also comfortable and user-friendly, making it a good choice for people looking to take an easy and comprehensive test of their sleep health.

The SleepImage System meets the definition of the channels required for using CPT 95800 for diagnosis and CPT 99543, 99454, 99457, and 99458 for remote patient monitoring. The device comes with a warranty for the medical professional, who will explain the user's responsibility for using the device, which is lent to the user to take the test. The SleepImage Ring is only available for healthcare providers to purchase. Those interested in using the SleepImage Ring will need to locate a sleep specialist who uses this at-home test as part of a sleep study package.

The FDA has also cleared other wearable ring devices for monitoring sleep quality and health data, such as the Happy Ring Health Monitoring System by Happy Health, Austin, TX, and the Belun Sleep System by Belun Technology, Hong Kong. These rings monitor health metrics such as sleep quality, blood oxygen level, heart rate, daily activity, body temperature, and brain activity. These devices can be used for the detection and diagnosis of various conditions, including sleep apnea, heart disease, stroke, hypertension, insomnia, dementia, and diabetes.

SleepImage Ring vs. traditional sleep studies

The SleepImage Ring is a comfortable and easy-to-use device that collects physiological data during sleep. It is worn on the finger and paired with the SleepImage app, allowing users to sleep soundly in their own beds without the discomfort of sleep labs. The ring is rechargeable and reusable, and its small, sleek design makes it a convenient choice for those seeking a sleep apnea test.

In contrast, traditional sleep studies, such as polysomnography (PSG), often involve multiple sensors and direct monitoring by sleep technicians, which can disrupt the sleep of the individual being studied. PSG examinations include frontal, central, and occipital electroencephalograms, electrooculograms, chin electromyograms, tibialis anterior electromyograms, ECGs, respiratory airflow measurements, thoracic-abdominal effort assessments, SpO2 monitoring, snoring detection, and body position tracking. This extensive setup requires specialised equipment and trained personnel, making it less accessible and convenient than the SleepImage Ring.

The SleepImage Ring is particularly beneficial for those who already use a CPAP machine, as it can be easily used alongside the device. It is also a good option for individuals who prefer to assess their sleep at home rather than in a sleep lab. The ring collects data on six channels, providing doctors with valuable information to evaluate symptoms of sleep apnea and insomnia, as well as differentiating between obstructive sleep apnea (OSA) and central sleep apnea (CSA).

While the SleepImage Ring offers convenience and comfort, traditional sleep studies in a lab setting offer advantages such as accuracy and direct monitoring by sleep experts. In-lab studies can provide a comprehensive assessment of sleep patterns and disorders, including OSA, CSA, and other sleep-related conditions. However, they may be more invasive and disruptive to the individual's natural sleep environment and routine.

The SleepImage Ring has been cleared by the FDA for use in both children and adults, and it can provide comparable output to PSG tests for diagnosing sleep apnea. It is important to note that additional testing may still be required, even after using the SleepImage Ring, as recommended by the user's healthcare team. The SleepImage Ring is not available for purchase by individuals and must be prescribed by a medical professional.
