In crowded subway cars, they are often sleepy and yawning constantly; in the office with doors and windows closed, they are stunned and dizzy; work in continuous high-intensity, tired during the day, insomnia at night... all these are similar to “sub-health” "The body reaction may be caused by the body's lack of oxygen.
A person can't have oxygen for 3 minutes. When the body inhales insufficient oxygen, it also has an adverse effect on the body. Short-term hypoxia may lead to decreased brain sensitivity, dizziness, headache, tinnitus, vertigo, and even weakness in the limbs. If the state of hypoxia lasts for a long time, it will also cause damage to tissues and organs and aggravate the symptoms of the disease. For example, the relationship between hypoxia and diabetes is very close. Diabetes easily causes an increase in tissue oxygen demand and insufficient oxygen supply, and the whole body is in anoxic state, resulting in microvascular function and structural damage. If the external environment does not provide enough oxygen, it is easy to promote the disease. Scientific high-pressure oxygen or atmospheric pressure and high-flow oxygen therapy should be carried out in time to play a good role in prevention and treatment of complications such as diabetic microangiopathy.
In general, hypoxia is likely to occur in the following populations, namely, the elderly, chronically ill patients, and mental workers who have been in high pressure for a long time. Old age will cause physical deterioration of the body, and the disease may cause damage to the lesion. Both of them will reduce the body's ability to obtain oxygen, and the utilization rate of oxygen will decrease, so it is more prone to hypoxia. Mental workers in high-pressure situations often use excessive brain and increase oxygen consumption. When simple lung respiration is insufficient to meet the body's oxygen demand, hypoxia will occur. In addition, acute traumatic hypoxia may occur in patients with traumatic brain injury, large-scale cerebral infarction, post-cardiopulmonary resuscitation, and sudden deafness. In this case, hyperbaric oxygen therapy is needed to alleviate the possible condition. Further damage and promote the repair of nerve function.
For more people, short-term hypoxia is more common in certain environments. For example, a closed and crowded space, a low-pressure environment with severe air pollution. The former can be alleviated by strengthening ventilation or leaving a confined space; the latter relies on better environmental protection measures. In the case of adverse reactions such as acute hypoxia, oxygen may be considered to relieve discomfort.
Medical research has found that scientific oxygen can indeed bring various benefits to the body, such as improving brain responsiveness, improving sleep, and alleviating disease symptoms. However, it should be reminded that because China's oxygen concentrator market is not perfect enough, the products are mixed. Ordinary consumers should not be convinced of the propaganda of “disease treatment, disease-free health care”. It is best to consult the relevant departments of the hospital for hypoxic-susceptible people to confirm whether they need family oxygen therapy and what kind of health care or treatment plan should be adopted. In general, the oxygen concentration of the household oxygen generator should be about 93%. For the health care population, the oxygen flow rate is usually 1 to 3 liters/minute, and the oxygen intake time is about 30 minutes per day.
