Introduction
In general, long-term oxygen therapy can improve lung function, but it should be conducted under the guidance of a physician. However, long-term oxygen therapy is not suitable for all healthy individuals. People who are physically healthy and have no underlying medical conditions typically do not require prolonged oxygen supplementation. Excessive oxygen intake may lead to adverse effects such as dryness of the nasal passages, nosebleeds, and in severe cases, even oxygen toxicity.
In general, long-term oxygen therapy can improve lung function, but it should be conducted under the guidance of a physician. The detailed analysis is as follows:
Long-term oxygen therapy is primarily suitable for patients with chronic respiratory diseases, such as chronic bronchitis, asthma, and chronic obstructive pulmonary disease (COPD). These conditions often lead to a gradual decline in lung function, causing symptoms such as chest tightness, shortness of breath, and difficulty breathing. By administering prolonged oxygen supplementation, the body's oxygen levels can be effectively restored, reducing stress on the lungs and promoting recovery of lung function, thereby improving the patient's respiratory condition.
Additionally, long-term oxygen therapy increases blood oxygen saturation and oxygen content, enhances metabolism, and enables the body to better absorb nutrients and eliminate toxic substances. It also helps strengthen the immune system and alleviate symptoms of hypoxia.
However, long-term oxygen therapy is not suitable for all healthy individuals. People who are physically healthy and free of medical conditions generally do not require prolonged oxygen supplementation. Excessive oxygen intake may cause adverse effects such as nasal dryness and nosebleeds, and in some cases, may even lead to oxygen toxicity.
