What will happen if you take in too much oxygen

Oxygen is a key substance for human metabolism, but excessive inhalation of oxygen may cause serious harm to the body. Inhaling oxygen at high concentrations for a long time may lead to oxygen poisoning, trigger a series of adverse physiological reactions, and even threaten life and health.

1. Oxygen poisoning

When the concentration of oxygen inhaled by the human body is too high, the oxygen content in the blood will increase abnormally, causing cell damage and symptoms of oxygen poisoning. Mild cases may present with headache, nausea, and vomiting, while severe cases may cause serious complications such as pulmonary edema and dyspnea.

2. Dry respiratory tract

High concentrations of oxygen are drying, and long-term inhalation will cause dryness of the respiratory mucosa, which may lead to symptoms such as sore throat and cough. Patients can flush their nasal passages with saline or sea salt water to relieve symptoms.

3. Atelectasis

Excessive oxygen inhalation may also cause atelectasis, which is the separation of the air film in the chest cavity, affecting the normal function of the lungs. Patients may experience chest tightness, dry cough and other symptoms and need to use amoxicillin capsules, cefuroxime axetil tablets and other drugs as prescribed by the doctor.

4. Retinal atrophy

High concentrations of oxygen may also cause damage to the retina, leading to vision loss or even blindness. Therefore, changes in vision should be monitored regularly for patients requiring long-term oxygen supplementation.

5. Metabolic disorders

Oxygen free radicals produced by excessive oxygen inhalation will attack human cells, cause metabolic disorders, and may even lead to serious diseases such as cancer. Therefore, oxygen inhalation therapy should be carried out under the guidance of a doctor, and the time and concentration of oxygen inhalation should be strictly controlled.

In conclusion, although oxygen is vital to sustaining life, excessive inhalation may pose serious health risks. Using oxygen inhalation equipment correctly and safely and following your doctor's advice are the keys to avoiding unnecessary risks.
