Yes. Long‑term oxygen therapy with the Jinyang portable oxygen concentrator is beneficial for COPD patients. It can significantly improve their quality of life and survival rate, and positively affect their exercise capacity and mental state. Typically, oxygen is administered via a nasal cannula at a flow rate of 1–2 liters per minute.

1. Improved tissue oxygenation and survival

When COPD exacerbates, lung function is severely impaired, making it difficult to meet the patient's ventilation and gas‑exchange needs, which can threaten life. Oxygen therapy provides sufficient oxygen to the body's tissues and organs, supporting normal metabolic demands and markedly enhancing both quality of life and survival.

2. Enhanced brain function and overall well‑being

Hypoxia (oxygen deficiency) can impair brain function, which in turn affects motor skills and mental health. By improving cerebral oxygen supply, oxygen therapy positively influences the patient's physical activity and psychological state.
