Home oxygen concentrators are small, household oxygen therapy devices that produce oxygen physically for daily supplementation in people with oxygen deficiency. Their core uses fall into the following categories:
I. Medical/Rehabilitation Uses (Primary)
* Chronic Respiratory Diseases
* COPD, Asthma, Emphysema, Pulmonary Fibrosis, Bronchitis
* Long-term hypoxia, shortness of breath, difficulty breathing, requiring long-term home oxygen therapy
* Cardiovascular and Cerebrovascular Diseases
* Coronary heart disease, Heart failure, Hypertension, Post-stroke Sequelae
* Improves myocardial and cerebral oxygen supply, relieving chest tightness, dizziness, and fatigue
* Post-operative/Major Illness Rehabilitation
* Post-operative and recovery period from severe illness, increasing blood oxygen levels and accelerating recovery
II. Daily Health Care for Middle-Aged and Elderly
* Decreased lung capacity, prone to hypoxia, drowsiness, and poor mental state in the elderly
* Regular low-flow oxygen therapy, relieving fatigue, improving sleep, and enhancing mental state
III. Pregnant Women/Special Populations
* Chest tightness, shortness of breath, and abnormal fetal movement during pregnancy, used when doctors recommend oxygen therapy
* High Altitude Living/ Travel can alleviate altitude sickness: headache, nausea, and difficulty breathing.
IV. Mental fatigue and sub-health: High-intensity mental work: dizziness and poor concentration after students preparing for exams, working overtime, or staying up late. Drowsiness and dizziness caused by hypoxia can be relieved with short-term oxygen inhalation.
