With the spread of the COVID-19 pandemic, the situation of disease control is facing many difficulties with new variants causing great damage to the economy and human society, currently many people are equipping themselves with oxygen generators for home use. However, according to the Ministry of Health, arbitrarily buying oxygen ventilators is unnecessary, causing waste because it cannot be used by oneself without sufficient expertise. So what should we pay attention to when using oxygen ventilators at home?

Artificial ventilation is indicated when the patient has oxygen deficiency and reduced alveolar ventilation. This is considered a method that can partially or completely replace the patient's spontaneous breathing rhythm.

SpO2 index is a vital sign of the body. Monitoring SpO2 index to check the amount of oxygen in the blood helps doctors detect abnormalities and handle them promptly.
