I. Medical Sector: Precise Lifesaving Protection
In hospital wards and clinics, oxygen concentrators are indispensable "lifesavers." At the Respiratory Ward of City First People’s Hospital, each bedside connects to an oxygen tube supplied by the central oxygen system. Equipped with large molecular sieve oxygen generators, the system delivers continuous, stable oxygen to ward terminals via pipelines.
"For patients with COPD, pulmonary fibrosis, and other respiratory diseases, long-term oxygen therapy improves conditions and quality of life," said Dr. Wang, Respiratory Department Director. "We adjust oxygen flow based on blood oxygen saturation to ensure optimal supply—higher flow for critically ill patients with low saturation, lower flow for stable cases to meet basic needs."
Portable medical oxygen concentrators are critical in emergency rooms. "Time is life when rescuing acute respiratory failure or myocardial infarction patients," noted Dr. Li, an emergency physician. "These devices provide instant oxygen, buying time for treatment. Equipped with real-time blood oxygen monitoring, they enhance rescue precision."
In primary healthcare, oxygen concentrators boost capabilities. "Previously, we had to transfer oxygen-dependent patients to larger hospitals," said Township Health Center Director Zhang. "Now, with medical oxygen concentrators, we’ve treated many acute respiratory cases, greatly facilitating local access to care."
II. Household Use: A Health Care Ally
Growing health awareness has brought home oxygen concentrators into daily life. Mr. Liu, 78, uses a compact unit for chronic bronchitis. "Inhaling oxygen for hours daily eases breathing and lifts my spirits," he said, demonstrating its simple operation. "It’s quiet and easy to adjust flow."
Pregnant women like Ms. Wang (7 months pregnant with gestational anemia) also benefit. "I worried about usability, but this lightweight device is easy to move. Oxygen relieves my dizziness and fatigue," she shared.
Rental services have emerged to meet short-term needs. "Our flexible rentals are popular, especially in winter’s respiratory peak," said a medical device company manager. "We offer home installation and maintenance for families renting for elders or children."
III. Plateau Regions: Essential for Hypoxia
High altitudes with thin air make oxygen concentrators vital for combating altitude sickness. A Lhasa homestay equips every room with them. "Tourists often suffer headaches or breathlessness—timely oxygen relieves symptoms. Our 24/7 supply ensures rest," the owner explained.
In remote plateau areas, they protect residents. "Previously, severe altitude sickness cases required long transfers to county hospitals," said a Nagqu village doctor. "Now, oxygen concentrators stabilize patients immediately, reducing severe cases from hypoxia."
They also support plateau transportation and construction. Qinghai-Tibet Railway trains have oxygen systems for passengers and crew. Highway construction sites equip dormitories and work zones to prevent altitude sickness, ensuring worker safety.
IV. Industrial Production: Efficiency Enabler
Oxygen concentrators underpin efficient industrial processes. In a steel mill’s workshop, oxygen injected into furnaces via pipelines intensifies combustion. "High-purity oxygen raises temperatures, speeds smelting, and improves steel quality," said the technical director. "Our industrial units produce thousands of cubic meters hourly, meeting full demand."
In chemicals, oxygen fuels reactions. "High-purity oxygen enhances efficiency and quality in chemical production," said a plant engineer. "Our cryogenic oxygen systems deliver ≥99.6% purity for stable raw material supply."
They also aid metal cutting/welding. "Oxygen-acetylene flames cut metals efficiently—purity directly affects precision," noted a machinist. "Our concentrators’ high-purity oxygen boosts cutting speed."
V. Special Environments: Emergency Rescue Gear
In confined spaces like mines and tunnels, oxygen concentrators are critical during hypoxia emergencies. A coal mine’s rescue warehouse stores portable and mobile units. "Underground risks like hypoxia and gas leaks make these devices lifelines for trapped miners," said the safety director. "We train miners in their use regularly."
Tunnels use them too. "Poor ventilation causes hypoxia—our installed systems pipe oxygen to work zones," said a tunnel project safety chief. "They support rescuers during emergencies."
They also aid disaster relief. Rescuers carry portables into earthquake or flood zones, ensuring oxygen for victims and themselves.
As technology advances, oxygen concentrators will further improve and expand applications. From saving lives to daily health, from industry to rescue, they contribute significantly to society. Their role will grow, bringing more health and safety to people.
