Snoring, almost everyone sleeps at one time or another, and in some serious cases, it affects the sleep of the partner’s family or roommates, and this is the reason why many people enter the hospital as a result. But, is the impact of snoring limited to this? Snoring, the written word is called “snoring”, often snoring, especially the snoring is very heavy people often feel poor sleep during the day, the spirit is not good, also easy to sleepy during the day, what is the reason? It turns out that people who often snore often have different degrees of narrowing of the upper airway in some planes, and in the case of reaching a certain degree, there will often be acute apnea between sleep, that is, we often hear that people who snore heavily tend to snore for a few seconds or even longer when they sleep, a phenomenon that is known in medicine as ” Sleep apnea syndrome” (OSAHS), and in people who snore a lot, the incidence has reached more than 20%! So, what harm can sleep apnea syndrome do to people? The sleep apnea syndrome we are talking about here refers to obstructive sleep apnea hypoventilation syndrome, which is a common type of sleep breathing disorder that causes repeated acute hypoxia and sleep fragmentation due to repeated partial or complete upper airway obstruction events during sleep, and patients with sleep apnea syndrome have repeated microarousals and sleep fragmentation due to repeated upper airway obstruction, so nighttime sleep The rhythm is seriously disturbed, and the duration of stage III and IV sleep (deep sleep) is very short, even without slow-wave sleep, so even though they sleep for more than ten hours a day, they still feel tired and drowsy, which is very likely to lead to a series of social hazards such as traffic accidents and production operative accidents. In addition, long-term oxygen deprivation will cause a decrease in blood oxygen concentration and an increase in blood viscosity, which will damage the lungs, heart and other organs, thus leading to the occurrence of some serious diseases, such as hypertension, coronary heart disease, arrhythmia, pulmonary heart disease, cerebrovascular accidents, endocrine disorders and neuropsychiatric disorders, which seriously endanger the health of patients and shorten their life span. And according to some recent studies, severe sleep apnea syndrome can also lead to ED (erectile dysfunction) in men and severe pharyngeal heterosensitivity disorder. So, how can sleep apnea syndrome be diagnosed with certainty? Currently, the gold standard for diagnosing OSAHS relies on PSG (polysomnography), where patients are observed, monitored and automatically recorded through continuous sleep throughout the night. In addition to pulmonary function tests and cardiac monitoring, it also includes EEG, EEG, EMG, EMG (diastasis, pharyngeal, chin muscles, etc.), and ear oxygen saturation. Through the above tests, we can understand the changes of the patient’s organism during sleep, as well as the nature (typing) and degree of sleep apnea, etc.
