hidden hypoxia has become a hidden health risk for many groups. Elderly people with declining physical functions, patients with chronic respiratory diseases, people recovering from serious illnesses, and those living in high-altitude areas often suffer from shortness of breath, chest tightness, dizziness, poor sleep, physical weakness, and slow physical recovery due to insufficient oxygen intake.

Breathing is the foundation of life; oxygen supply is the line of defense for health. From clinical emergency care in primary hospitals to daily oxygen care at home, from relieving hypoxia in plateau areas to stable energy supply in industrial scenarios, the stable and efficient supply of oxygen has always been the core demand for protecting life and ensuring production.
