To understand the difference between a household oxygen concentrator and a ventilator, we must first know the principles and functions of the two.

Normally, breathing is the action of exhaling and inhaling, which makes our alveoli and airway orifices produce an active negative pressure difference to meet the needs of physical ventilation. In some people, obesity, thick and thick pharynx, abnormal thyroid function, etc., may cause airway obstruction or weakened alveolar tone, leading to breathing disorders, snoring, sleep apnea and other phenomena.

The role of the ventilator is to provide air flow like an electric fan, and direct a constant and gentle air flow to the airway of the human body through a mask, to help or replace these people with breathing disorders to complete their breathing and meet the needs of physiological ventilation.

When blood oxygen saturation is low, people will experience hypoxia, which is mainly manifested as dizziness, chest tightness, memory loss, and loss of appetite. Long-term hypoxia can lead to insomnia, premature aging, and cardiovascular and cerebrovascular diseases. Oxygen concentrator is an important means to solve the problem of hypoxia.
At present, the most common household oxygen concentrator on the market is a molecular sieve oxygen generator. This oxygen generator uses the PSA method (pressure swing adsorption) to directly extract oxygen from the air. In short, the oxygen in the air is separated through molecular sieve. , And then delivered to the human respiratory tract.

Since the oxygen produced by the household oxygen concentrator comes from air, there is no need for oxygen storage equipment and a fixed oxygen source. For people who need long-term oxygen inhalation, the cost performance is higher and more convenient than bottled oxygen or hospital oxygen inhalation. The standard oxygen concentration is 90%±3%, which is an important reference for us to purchase a household oxygen concentrator.

In summary, we can simply summarize the difference between ventilator and oxygen concentrator as: ventilator is used to solve ventilation problems, suitable for people with poor breathing or unable to breathe spontaneously, while oxygen concentrator is used to solve hypoxia problems, mainly suitable For people with low blood oxygen saturation.
