Explanation: the percentage of oxygen in the gas delivered to the patient's body by the ventilator;

Adjustable range: JIUJIUXIN ventilator adopts pneumatic electronic control mode, and the adjustable range of oxygen concentration is 40% - 100%;

Common values: oxygen concentration is generally set at 40%;

Application skills: the oxygen concentration can be increased to improve the patient's blood oxygen;

Application skills: before and after sputum suction, patients are given high oxygen concentration ventilation, which is conducive to stable blood oxygen value of patients;

Note 1: if the oxygen concentration exceeds 60% for a long time, there will be a risk of oxygen poisoning;

Note 2: when using high oxygen concentration, the oxygen consumption of ventilator will increase.
