The doctor tested him and found that when he was sleeping, the soft tissue of the upper airway was relaxed, leading to throat obstruction and hypoxia, and the brain sent a message to him to breathe vigorously, resulting in severe snoring. Mr. Li turned out to be suffering from sleep apnea.<\/p>\n
Sleep apnea is more common in obese people due to the accumulation of fat on both sides of the neck and throat. If the BMI reaches the level of 40 to 50, it is likely to suffer from sleep apnea for a long time, or myocardial infarction may be induced by lack of oxygen. Sudden death cases have occurred in foreign countries. For moderate to severe patients, if they delay seeking medical treatment for 5 to 10 years, the risk of stroke and high blood pressure can be 3 to 5 times higher than that of normal people. Professional drivers are 3 to 5 times more likely to encounter traffic accidents due to decreased concentration.<\/p>\n
To calculate the sleep apnea index, the number of upper airway apneas experienced per hour can be used as an indicator. For adults, 5 to 15 episodes can be regarded as mild, 15 to 30 episodes are moderate, and more than 30 episodes are quite serious. Traditionally, patients have to stay in the hospital overnight for a sleep test. Through a multi-channel sleep analyzer, they can understand the brain waves of light sleep, deep sleep time, and sleep physiological conditions. However, the admission test is time-consuming, and the hospital environment is not easy for patients. fall asleep. Fortunately, the current testing equipment is very portable, and the staff can bring the equipment to the door, connect several detection lines to the tester, and then test at home. After completion, they will come to collect the equipment, and then hand it over to the doctor to explain the diagnosis report.<\/p>\n
At present, positive air pressure machine (CPAP) is an effective method to treat sleep apnea. The principle is to use the air pressure generated by the device to open up excess tissue that blocks the upper airway, so that the lungs can inhale air, prevent suffocation, and restore smooth breathing. After the patient's symptoms are relieved, the duration of deep sleep at night will increase, and the mental state will improve during the day, which will improve the overall health level.<\/p>\n
