What is the purpose of receiving oxygen therapy?

Oxygen therapy refers to delivering pure oxygen to patients via devices such as oxygen masks, nasal cannulas, or face masks, and is an important therapeutic approach. Generally, the benefits of oxygen therapy include providing respiratory support, promoting the binding of oxygen to hemoglobin, reducing cardiac workload, improving tissue repair and healing, and enhancing metabolic function. Specific details are as follows:

1. Providing respiratory support: Oxygen therapy can supply additional oxygen to patients experiencing difficulty breathing or suffering from hypoxemia.

2. Promoting the binding of oxygen to hemoglobin: Delivering higher-purity oxygen increases the combination of oxygen with hemoglobin, thereby raising blood oxygen levels and helping alleviate symptoms of hypoxia.

3. Reducing cardiac workload: In patients with heart disease, supplemental oxygen can increase arterial oxygen partial pressure, thus reducing the heart's workload.

4. Improving tissue repair and healing: Insufficient oxygen supply after injury or trauma may delay wound healing. Oxygen therapy ensures adequate oxygen delivery, promoting tissue repair and recovery.

5. Enhancing body metabolism: Supplementing oxygen improves blood circulation, promotes cellular metabolism, and accelerates the elimination of toxins from the body.

It is important to note that oxygen therapy should be administered under a doctor's supervision. Self-administration should be avoided to prevent oxygen toxicity. During treatment, patients should closely monitor their physical condition and promptly consult a physician if any abnormalities occur.
