Is too much oxygen good for your health?

It can lead to oxygen poisoning in serious cases.

The higher the oxygen concentration, the better. If you inhale high concentration oxygen for a long time, you will have symptoms of oxygen poisoning. Cough, chest tightness and chest pain are the main clinical manifestations of oxygen poisoning in the early stage. Some patients with oxygen poisoning will have fundus hemorrhage, and severe cases may lead to blindness due to retinal detachment and posterior lens leukoplakia.

Healthy people who inhale this high flow of oxygen may have headaches and nausea. In addition, too high oxygen concentration may cause some uncomfortable reactions in the airway. Oxygen inhalation is mainly aimed at people with severe respiratory diseases, severe lung diseases and severe heart diseases complicated with cardiac insufficiency, so it is suggested that ordinary people should not take oxygen casually to avoid endangering their health.
