Difference Between Ventilator And Oxygen Machine

Sep 17, 2018

The difference between a ventilator and an oxygen generator is that they use different principles and use different people.


1. Principle of ventilator: Inspiratory action produces pleural negative pressure during spontaneous ventilation, pulmonary alveolar and airway negative pressure appear in passive pulmonary expansion, which constitutes the pressure difference between airway mouth and alveoli and completes inhalation; after inspiration and thorax The lungs are elastically retracted, creating an opposite pressure difference to complete the exhalation. Therefore, normal breathing is due to the body's "active negative pressure difference" between the alveoli and the airway mouth through the breathing action to complete the inhalation. The thoracic and pulmonary elastic retraction after inhalation produces a passive positive pressure difference between the alveolar and airway mouth and exhales. To meet the needs of physiological ventilation.


        Mainly used for: sleep snoring, hypoxemia, mild lung disease, old chronic support, dyspnea, COPD, emphysema, asthma, severe respiratory failure, heart failure, carbon dioxide retention, ALS motor neuron disease, muscle Atrophy and other diseases.

2, the principle of oxygen machine: the use of molecular sieve physical adsorption and desorption technology. The oxygen concentrator is filled with molecular sieves. When pressurized, the nitrogen in the air can be adsorbed, and the remaining unabsorbed oxygen is collected, and after purification, it becomes high-purity oxygen, which is generally not suitable for use by critically ill patients!

       Mainly used for: (oxygen therapy and health care) A. Respiratory diseases such as pneumonia, bronchitis, chronic bronchitis, viral respiratory infections, asthma, emphysema, pulmonary heart disease. B. Cardiovascular and cerebrovascular diseases such as hypertension, heart disease, coronary heart disease, myocardial infarction, cerebral thrombosis, cerebral ischemia, brain dizziness, atherosclerosis, etc. C. Plateau hypoxic conditions such as high altitude pulmonary edema, acute mountain sickness, chronic mountain sickness, high altitude coma, high altitude hypoxia. D. People who are prone to lack of oxygen, such as middle-aged and elderly people, pregnant women, students who have been engaged in mental work for a long time, company employees, and government cadres; those who have been engaged in underground or confined space for a long time, and those who are overworked with insufficient labor and oxygen supply. E. Other people who need oxygen therapy, such as frail and sick people with poor immunity, heat stroke, gas poisoning, drug poisoning, etc.
