One in 15 adults in the U.S. has sleep apnea, which accounts for approximately 18 million people. The prevalence of this sleep disorder may be higher because many people do not realize that the common discomforts of their bodies are related to this disease. The incidence of OSA in stroke patients is as high as 69%-77%. Among patients with type II diabetes, the incidence of OSA is as high as 66.7%, while the incidence of these two diseases in the general population is only 5 %. In sleep apnea, breathing will stop and start repeatedly. Sleep apnea is the most common cause of sleep-disordered breathing (SDB), a general term that describes breathing difficulties during sleep. The specific level of assessment and treatment plan will rely on sleep tests for diagnosis. That’s where wearable pulse oximeter steps in. Read on to see what makes this device useful.
Respiratory sleep test& Sleep report
Also known as a limited respiratory sleep study, the respiratory sleep test is utilized to diagnose SDB. As long as the patient wears the oximeter and sleeps indoors for one night during the examination, the monitoring system will automatically issue a sleep analysis report based on the raw data collected by the equipment and give reasonable suggestions. The entire monitoring process is painless, risk-free, safe, and accurate. Sleep reports generally cover the following
- AHI (Sleep Apnea-Hypopnea Index): Test the average number of apneas and hypopneas per hour of sleep. The number of times per hour that the airway is blocked by approximately 100% (apnea) or by approximately 50% (hypopnea).
- Minimum blood oxygen saturation: the degree of sleep hypoxia.
- The longest apnea/hypopnea time (seconds): the longest duration of airway obstruction during sleep by approximately 100% (apnea)/airway obstruction by approximately 50% (hypopnea), that is, the duration of hypoxia time.
- Apneas/hypopneas: the total number of airway obstructions of about 100% (apnea) / airway obstruction of about 50% (hypopnea) during sleep, that is, the total number of repeated hypoxia at night.
- Sleep stage: it reflects the sleep quality. The decrease in the time and proportion of the R phase (REM phase, eye movement period) and N2 phase (NREM2 phase, deep sleep phase) suggests the decrease of deep sleep and poor sleep quality.
Hospita
In addition to electroencephalogram (EEG)，electromyography (EMG), electrooculography (EOG), electrocardiogram (ECG), the PSG test commonly used in hospitals includes physiological signals from more than ten channels, including thoracic and abdominal respiratory tensiograms, nasal and oral ventilation, postural body movements, blood oxygen saturation, and penile cavernosal muscle volume. To be performed this PSG test, electrodes are placed in multiple locations under the tester’s eyes, mandible, chest, and abdomen. This is quite uncomfortable for the tester. Also,the altered sleep environment makes it difficult for the tester to fall asleep, which the shortened effective sleep time or recording time may cause errors in the report. Moreover, the sleeping position caused by wearing the instrument tends to be supine, OSA may be overestimated. In addition, the examination and analysis of PSG are time-consuming and require more labor and material resources. In the hospital, it takes at least 3 hours for a very skilled medical staff to analyze a standard PSG case.
For this reason, an advanced respiratory sleep test such as a wearable pulse oximeter could be a more suitable choice. It provides deep insight into patients’ breathing, but at lower costs. This is particularly useful in mild to moderate cases of sleep apnea.
Household
Millions of people have SDB, but not all of them can afford expensive sleep study tests in hospitals. Testing at home by using a wearable pulse oximeter has become a practical and easy way to assess the quality of sleep, detect low oxygen levels, measure heart rate, and more. Sleeping in a hospital or lab bed with machines and other equipment can be hard to have a good sleep for many people. And the unfamiliar and uncomfortable sleep state will affect the accuracy of experimental data. In these cases, home testing is a comfortable way to assess sleep. This type of testing is most suitable in persons with mild or moderate sleep apnea. It’s also useful for persons who are at risk of sleep apnea. These devices and tests are not just for persons with sleep apnea, but also other loud snorers, persons with COPD, pneumonia, asthma, just to name a few.
Viatom wearable pulse oximeter and sleep breathing solutions
As a high-tech company, Viatom is dedicated to innovation in the devices and features they provide. Viatom wearable pulse oximeter, O2Ring, is the latest example of cutting-edge technology in the health and management of various conditions. O2Ring is a wearable medical-grade device created specifically to monitor and track sleep. When the percentage is lower than the preset threshold, and the heart rate is lower or higher than the preset threshold, O2Ring will tell you and mark it in the report. When the wearable pulse oximeter is connected to the APP via Bluetooth, the data will be uploaded automatically. Its built-in memory is allowed to store four groups of 10 hours of data on the wearable oximeter. Whether for pre-diagnosis or post-treatment monitoring, Viatom oximeters are well integrated into the sleep-disordered breathing project, and offer services to assist in app development, responding to any technical challenges with accurate measurements and a comprehensive database.
Applications of wearable pulse oximeters and respiratory sleep tests
As mentioned above, the O2 Ring wearable oximeter can be integrated into sleep breathing solutions and respiratory sleep tests. And the data from sleep tests are useful in analyzing the users’ physical condition. From the sleep tests of OSA groups, some diseases are related to OSAS, which can be found using wearable pulse oximeters.
Polycystic ovary syndrome
A growing number of reports suggest an association between PCOS and OSA. PCOS is one of the common endocrine disorders in women of reproductive age and is characterized by hyperandrogenism, ovulation disorders, insulin resistance, and neuroendocrine disorders. The prevalence in the general population is 8% to 13%. According to research, women with PCOS are more likely to suffer from OSA than the general population. These women are more likely to develop hypertension, hyperlipidemia, insulin resistance, and abnormal glucose metabolism. Therefore, early detection and treatment of OSA play an important role in improving metabolic disorders and preventing complications in women with PCOS.
Obstructive sleep apnea syndrome in children
Repeated intermittent hypoxia and sleep fragmentation in OSA can induce cellular damage in the central nervous system and affect the neurocognitive function of children. This will lead to varying degrees of attention, memory, and intellectual decline in children. The prefrontal cortex in children is an important part of the body that controls cognition, execution, and memory. Hypoxemia also causes a thinning of the prefrontal cortex with frontal dysfunction, leading to prefrontal dysfunction and executive deficits in children. Parents and doctors can use a sleep test to detect and treat children’s OSA as soon as possible to prevent irreversible neurological damage caused by OSA from affecting neurocognitive recovery.
Cancer
Animal and in vitro cancer models have shown that the controlled exposure of chronic intermittent hypoxia and sleep fragmentation of OSA can trigger oxidative stress and systemic inflammation and enhance the activity of carcinogenic pathways. More and more evidence shows that OSA may be an important risk factor for the occurrence and development of cancer in recent years. Epidemiological studies in 2012 first confirmed that OSA patients have a higher cancer incidence and cancer mortality. It has been reported that increased frequency of suppressor non-killing T cell expression in patients with OSA after 12 months of CPAP treatment. These have verified that effective treatment of OSA patients can help prevent cancer.
