The difference between ventilator and oxygen generator

Jul 04, 2019

Household ventilators and oxygen generators are common medical devices in our homes, but many people often confuse these two together. What is the difference between a home ventilator and an oxygen generator?

The working principle of the ventilator: the normal breathing of the human body is due to the "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 the alveolar and airway mouth passively. Exhale with a pressure difference to meet the needs of physiological ventilation. When the home ventilator autonomously ventilates, the inspiratory action produces a negative pressure in the chest, and the passive expansion of the lungs causes alveolar and airway negative pressure, which constitutes the pressure difference between the airway mouth and the alveoli and completes the inhalation; the thoracic and pulmonary elastic back after inhalation Shrink, generate the opposite pressure difference to complete the exhalation.

Oxygen machine working principle: using molecular sieve physical adsorption and desorption technology. The oxygen generator is filled with molecular sieves, and the nitrogen in the air is adsorbed during pressurization, and the remaining unabsorbed oxygen is collected, and after purification, it becomes high-purity oxygen, and then transported through a nasal catheter or an oxygen mask. Our body. Generally not suitable for use by critically ill patients!
Respirators for people: Household ventilators are mainly used for patients with abnormal nasal development, hypertrophy of the pharynx and thick, thyroid dysfunction, obesity and other patients in the case of snoring or other sleep apnea syndrome!

Oxygen machine for people: chronic bronchitis & emphysema and other respiratory diseases, hypertension and coronary heart disease cardiovascular and cerebrovascular diseases, cardiopulmonary dysfunction, sleep apnea syndrome and other sub-health status, acute and chronic deficiency caused by other causes Oxygen symptoms.
