The medical oxygen generator must be a 3-liter machine. When the new machine leaves the factory, the oxygen concentration must be greater than or equal to 90%. When the oxygen concentration is lower than 82%, the molecular sieve must be replaced. In addition, the state requires medical oxygen generator to have two functions of oxygen concentration indication and fault indication alarm to remind users.

Then, why the oxygen concentration of the oxygen generator must reach 93% before it is qualified? This is because when the medical oxygen generator is used to inhale oxygen, it will also inhale some air containing 20.98% oxygen purity, so that the oxygen concentration really inhaled will also be diluted. According to the test, the oxygen concentration in the throat is about 45%. 

According to the structural characteristics of the human body, the inhalation of oxygen has to go through a 32 level attenuation process. In fact, when the oxygen concentration is 93%, the oxygen concentration used by the human body after oxygen inhalation is about 30%. 

Therefore, in order to ensure that patients can normally receive oxygen assisted treatment, the oxygen concentration must reach 93% or equal to 93%, in order to ensure the oxygen demand of patients.
