What Is The Difference Between Oxygen Concentrator And Ventilator?

Ventilators output air, which is an effective means to artificially replace the function of voluntary ventilation; The oxygen generator outputs oxygen to improve the oxygen content of human body.
The respirator can adjust the frequency, size and intensity of breathing, while the oxygen generator can only adjust the oxygen flow.
Ventilator is used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation. Oxygen generator is an auxiliary means to correct pathological hypoxia, such as respiratory failure, chronic bronchitis, cerebrovascular disease, coronary heart disease, etc.
