How to buy a safe and reliable hot sale oxygen concentrator? Don't worry, today we will talk about how to avoid pits and choose a suitable and easy-to-use oxygen generator.

　　1. Types of hot sale oxygen concentrators

　　From the functional point of view, oxygen generators are divided into two types: health care and medical. Health care oxygen generators are generally suitable for mental workers (such as students, white-collar workers), pregnant women, and normal elderly. Medical oxygen generators are generally suitable for people with pathological oxygen intake (including patients with cardiovascular and cerebrovascular diseases, patients with respiratory system diseases, diabetic patients, etc.).

　　2. The oxygen concentration of the hot sale oxygen concentrator

　　The oxygen concentration of the hot sale oxygen concentrator refers to the size of the oxygen content. In layman's terms, it is the purity of the oxygen output from the oxygen generator. Different oxygen generators have different oxygen concentrations.

　　3. Oxygen flow rate of hot sale oxygen concentrator

　　Take a 5L machine with an oxygen concentration of 90% as an example: when the oxygen flow is controlled at any flow rate within 5L/min, the oxygen concentration will be greater than 90%. If the oxygen flow exceeds 5L/min, the oxygen concentration of the hot sale oxygen concentrator will not be. will be greater than 90%. The choice of oxygen flow rate during oxygen inhalation generally depends on the degree of hypoxia and the underlying disease of the oxygen inhaler.

　　4. The noise level of the hot-selling oxygen concentrator

　　It is recommended that consumers choose a hot-selling oxygen concentrator with noise reduction function and the noise is lower than 45-48 decibels, otherwise, it may affect the rest of individuals or others.
