The efficacy of long-term oximetry has already been evaluated for monitoring patients with Sleep Apnea. However, it also increases the demands of a wearable with respect to battery power, graphics control and signal processing. Continuous monitoring of oxygen saturation combined with pulse rate during sleep provides excellent validation results for this application. Manufacturers will continue to add external sensors to consumer wearables that allow them to assess other signals.Īn oximetry probe that measures the oxygen saturation of the wearer’s blood is one of the most promising types of new sleep apnea technology. How Do Wearables Help With Sleep Apnea Studies and Sleep Centers?Ĭlinicians can accurately estimate sleep behavior in a sleep center for up to 42 minutes by using smartphones that analyze light, noise, and acceleration, according to a 2013 paper published at the 7th International Conference on Pervasive Computing Technologies for Healthcare. HSAT systems also need to evaluate the severity of the Sleep Apnea when reporting measurements. This evaluation scheme thus allows new sensors and software to meet the criteria for a successful diagnosis of Sleep Apnea. For example, it evaluates an HSAT’s ability to distinguish between central and obstructive apnea, which is vital for developing an effective treatment plan. The SCOPER process checks the functions needed to characterize Sleep Apnea rather than simply merely counting individual apnea events. This acronym indicates these functions as follows: The SCOPER scheme has been developed to evaluate and categorize HSAT systems by validating the most important functions for diagnosing Sleep Apnea. However, the testing capabilities of HSAT devices have been getting more accurate and specific to Sleep Apnea. The reference standard for the diagnosis of Sleep Apnea remains cardiorespiratory polysomnography (CP), which is a multi-parametric sleep study of heart and lung functions. The rapid development and application of a sleep apnea tracker is largely due to the increasing prevalence of Sleep Apnea. These devices included smartphones, smartwatches, and other wearables. National Library of Medicine assessed the use of home Sleep Apnea testing (HSAT) devices for assessing Sleep Apnea. How Do Wearables Track Sleep?Ī 2018 study published in the U.S. Neural networks and statistical classification are currently the most promising data mining techniques for the data gathered by wearables. They also have great potential for generating big data, so researchers are shifting their focus to the development of algorithms that will provide insight into the collected data. Wearables can collect biometric data to provide valuable information on the heart, brain, and muscles. Other current applications for wearables are found in navigations systems, advanced textiles, and healthcare, especially elder care. Professional athletes are also using wearables to obtain real-time monitoring and feedback on physical functions such as movements and energy expenditure. Smart watches and activity trackers are some of the best-known examples of wearables in consumer electronics, although its uses are expanding rapidly as the technology develops. The cost of wearable technology dropped to a level that would allow widespread adoption by 2009, and sales began growing rapidly by 2013. They often have internet connectivity, making them part of the Internet of Things (IoT). What Is a Wearable?Ī wearable device, or wearable, is an electronic device with a micro-controller that can be worn directly on the body or incorporated into clothing. CPAP is effective in improving the outcome of Sleep Apnea, but patient compliance can be a limiting factor due to the discomfort of long-term use. This technique uses pressurized air to keep the patient’s airway open, typically by wearing a facial mask connected to a machine. Wearable devices are an unobtrusive method for obtaining the necessary data with minimal effect on the patient.Ĭontinuous positive airway pressure (CPAP) is the most common treatment for moderate to severe Sleep Apnea. These technologies can also allow researchers to investigate the causes of Sleep Apnea to develop better treatments. The diagnosis and monitoring of Sleep Apnea requires cost-effective wireless technologies, especially in areas where doctors and patients are geographically separated. Wearables are being used as a sleep tracker with increasing frequency. People with Sleep Apnea often feel sleepy or tired during the day, and it may also cause hyperactivity in children. These disruptions may last for as long as a few minutes and can occur many times, typically after loud snoring. Department of Health and Human Services defines Sleep Apnea as a disorder characterized by disruptions in breathing such as pauses or periods of shallow breathing while sleeping.
