Many people always think that snoring (commonly known as snoring) is a common thing, and it is also a good performance of sleep. I am not aware of the many potential dangers hidden in the seemingly mundane sound of snoring. More than one person will make such a snoring sound, and many of them have respiratory arrest during sleep, resulting in the normal oxygen supply of the body being seriously affected. Under normal circumstances, a clear airway allows air to enter and exit a person’s lungs freely. In sleep apnea syndrome, the upper airway is blocked during sleep, temporarily stopping breathing for a few seconds to several minutes, which can occur hundreds of times a night, leaving the patient without oxygen and often waking up suddenly, making it difficult to fall asleep and get enough sleep. Sleep apnea syndrome is an independent risk factor for coronary heart disease, as are hyperlipidemia, hypertension, diabetes, smoking and obesity. About 30% of patients with coronary artery disease have obstructive sleep apnea syndrome and 69% of patients with myocardial infarction. Sleep apnea syndrome causes chronic intermittent hypoxia, resulting in abnormal oxygen metabolism, which affects the patient’s blood pressure, blood glucose and lipids and causes damage to the cardiovascular system. In addition, any apnea event can trigger the onset of myocardial ischemia and the occurrence of asymptomatic myocardial infarction and sudden death during sleep. In addition to snoring, patients with sleep apnea syndrome may also have the following symptoms, such as: apnea, holding awake and hyperactivity, excessive sweating and urination, insomnia and dreaminess, and correspondingly many easily ignored phenomena during daytime, such as: fatigue and drowsiness, dry throat and bitter breath after waking up, morning dizziness and headache, irritability, memory loss, mental inattention, sexual dysfunction and bilateral lower limb edema, and other manifestations of chronic fatigue syndrome. However, these symptoms and signs are non-specific and cannot be used to make a definitive diagnosis, but the more symptoms you have, the more likely you are to have sleep apnea. The symptoms alone do not confirm the diagnosis of sleep apnea, but should be combined with a physical examination and sleep monitoring to confirm the diagnosis. Patients who are suspected of having obstructive sleep apnea should go to a sleep center for the appropriate diagnosis. The main diagnostic instrument is polysomnography, a non-invasive examination technique that allows diagnosis by monitoring breathing, chest and abdominal movements, blood oxygen saturation and other indicators during sleep. If the diagnosis of sleep apnea syndrome is made, patients should first pay attention to changing their lifestyle, such as losing weight, avoiding alcohol and sedative sleeping medications, quitting smoking, and sleeping in the lateral position. Surgical treatment, intraoral appliances and positive airway pressure are also available. The choice of treatment plan needs to be individualized based on the severity of the disease, the patient’s complaints, the impact of the disease on daytime work life, occupation, and cardiovascular risk factors. The aim is mainly to reduce the risk of death and the occurrence of cardiovascular diseases in patients, to reduce the occurrence of production and traffic accidents, and ultimately to reduce the incidence of sleep apnea-related diseases and mortality, and to improve the quality of life and life of patients.
