Paroxysmal dyspnea caused by nocturnal snoring can cause insomnia
Paroxysmal dyspnea during sleep refers to snoring and poor ventilation during a period of time during sleep. or even apnea. There are two major factors, physiological and pathological, which are more common in middle-aged and elderly men.
Occlusion of the upper airway during sleep is a major cause of nocturnal paroxysmal dyspnea. The process of occlusion is generally: during sleep, the muscle tension of the whole body is reduced, the muscles around the upper airway are also relaxed, the tongue base and soft palate are relaxed and move backward and downward, and finally the upper airway is extremely narrowed or completely blocked.
For obese people with short necks, the upper airway becomes quite narrow due to the compression of the adipose tissue around the neck. In addition, the base of the tongue and the soft palate sink backward and downward during sleep, which is very easy to cause the upper airway to be compressed. Difficulty breathing due to occlusion.
The occlusion time is generally 10 to 30 seconds. During this time, the person is in a state of suffocation. Although breathing is suspended, the metabolic activities inside the body have not stopped. The oxygen content in the blood and tissue fluid gradually decreases, and metabolism produces carbon dioxide gradually increased. Both of these changes are excitatory factors for the respiratory center. When the respiratory center is excited to a certain extent, breathing starts again. The first breath that resumes is a bit like the inhalation of a wheezing patient, dominated by the thorax, and the movement is sharp. Since the upper airway is quite narrow at this time, when the rapidly inhaled airflow passes through, it vibrates the surrounding soft tissues, resulting in a loud snoring sound.
There is a condition called “Sleep Apnea Syndrome”. This kind of patient will have apnea during sleep, and his family has to push him to wake up in order to prevent him from “dead past”. This disease is generally caused by the sleep and wakefulness dysfunction of the brain caused by mild viral infection of the central nervous system. In addition to infection, there are other factors that cause sleep apnea syndrome. Experts remind patients to look carefully.
