Does oxygen really refresh you?
Some netizens said that it did have an effect
But others say it is useless
There were even people who were poisoned by inhalation ...
A 32-year-old woman followed suit and bought an oxygen inhaler
Pulmonary oxygen poisoning was diagnosed after using two bottles
Recently, Ms. Liu, 32, of Wuhan, Hubei Province, saw that the online "oxygen artifact" was selling very hot, and she happened to be preparing for the exam recently, with greater pressure and lack of sleep. In order to "refresh her mind", Ms. Liu purchased a portable oxygen respirator. Unexpectedly, after using two bottles a week, I had symptoms of dry cough and chest pain. When he came to the hospital, he found that the bronchial mucosal edema, accompanied by scattered erosions, some of the cell edema with necrosis, peripheral fibrous tissue hyperplasia, was diagnosed as pulmonary oxygen poisoning.
The doctor analyzed that it was precisely because of Ms. Liu's high-flow and high-frequency oxygen intake for a week, which caused oxygen accumulation and lung and other tissue damage.
Doctor's Reminder:
Except for special patients, normal people do not need oxygen
Blind supplementation of oxygen is risky
Experts said that the average person refers to pulse oxygen saturation of about 97%, higher than the critical value of 93% oxygen inhalation, the oxygen content in the air is enough to use, and in most cases there is no lack of oxygen. In addition to some special patients, normal people do not need oxygen, oxygen to refresh the mind not only has no scientific basis, blind oxygen supplementation may even cause a certain burden on the user's body, such as: oxygen poisoning.
Li Feng, chief physician of the Department of Respiratory Medicine, Chest Hospital Affiliated to Shanghai Jiao Tong University School of Medicine: Oxygen poisoning may first manifest as eye discomfort, such as blurred vision or eye pain. Then there will be brain discomfort, such as nausea, vomiting and even coma. The respiratory system will also cause pulmonary edema due to oxygen inhalation into the lungs, which may be manifested as cough, chest tightness, chest pain, etc.
For pregnant women and the elderly who need to supplement oxygen as advertised by businesses, they need to be cautious.
Li Feng said that whether pregnant women and the elderly need oxygen can not be generalized, if pregnant women do not have asthma, no other diseases, no lack of oxygen is not recommended to take oxygen, because pregnant women inhaling high concentrations of oxygen will cause fetal vision problems.
If the elderly suffer from chronic coronary heart disease, COPD and other diseases, and chronic hypoxia, they can take oxygen under the guidance of a doctor.
Oxygen is generally only needed if:
1. Respiratory diseases: such as asthma, bronchopneumonia, pneumothorax, emphysema, atelectasis, etc.
2. Cardiac insufficiency: such as heart failure, it can make the lungs congested and cause difficulty breathing.
3. Dyspnea caused by various poisoning: such as carbon monoxide poisoning, barbiturate drug poisoning, etc., so that oxygen cannot penetrate into the tissue by capillaries and produce hypoxia.
4. Coma patients: such as comatose patients caused by cerebrovascular accident or craniocerebral injury, the center is inhibited and causes hypoxia.
5. Others: such as patients after some surgical operations, patients with massive bleeding shock, long labor or abnormal fetal heart sounds.
Therefore, if the normal population feels refreshed after inhaling oxygen, it may be just a psychological effect, not to mention if you buy some unqualified and fake oxygen generators, it is more likely to inhale "fake oxygen", causing harm to the user's body!
