1. Two flowmeter oxygen concentrator have "four fears"

　　Afraid of fire, heat, dust, tide

　　2. When the Two flowmeter oxygen concentrator absorb oxygen, pay attention to proper heating and humidification

　　Keep the temperature at 37°C and the humidity at 95% to 100%. The inhaled oxygen should be passed through a humidification bottle and necessary heating device to avoid inhalation of dry and cold oxygen to stimulate and damage the airway mucosa, as well as the "scavenger" that causes sputum drying and affects cilia. "function, etc.

　　3. When working, do not place the flowmeter float on the zero position

　　During the oxygen inhalation process of the Two flowmeter oxygen concentrator, pay attention to check whether the flowmeter float is in the correct scale position.

　　4. The Two flowmeter oxygen concentrator should pay attention to the start-up operation and maintenance

　　If the molecular sieve oxygen generator is not used for a long time, the activity of the molecular sieve will decrease

　　5. Cut off the power supply when not in use

　　Reduce the consumption of machines and energy, but also for fire safety.

　　6. Oxygen absorption requirements for Two flowmeter oxygen concentrator

　　For patients with carbon dioxide retention, the oxygen flow should not exceed 3 L/min, and 1 to 2 L/min is appropriate, because high-concentration oxygen inhalation can cause respiratory depression in such patients and worsen the condition; pregnant women should follow the doctor's advice when inhaling oxygen, and should not blindly take it on their own. Prolonged high-concentration oxygen inhalation.
