First of all, let’s make clear what the medical ventilator is. A ventilator is a machine that is used to help a patient breathe. This ventilator breathing machine pumps oxygen into the lungs of the patient and removes carbon dioxide out of the patient through a tube. Simply speaking, a ventilator is a fairly useful technological equipment which is designed to breathe for somebody who is unable to breathe effectively on their own.  

Next, how does a ventilator work? Well, a ventilator machine mainly have two important functions. On the one hand, it helps the patients get more oxygen into the lungs. On the other hand, it also can take carbon dioxide out of the patient.

Lungs are interwoven with blood vessels. Through the blood vessels, oxygen gets into the bloodstream and carbon dioxide gets carried out. COVID-19 makes this exchange very difficult, because a pneumonia patient’s lungs are inflamed and filled with fluid. Therefore, we could know that the use of ventilators can not cure COVID-19, but it helps support lung function while a patient’s body is fighting the infection.

A ventilator essentially helps a patient’s lungs accomplish their task. Modern ventilators consist of a pump machine and a tube. Our ventilation machines are divided into two groups: the HS-501S type (Non-invasive ventilator) and the VG70 type (Invasive ventilator).

Invasive ventilator: It requires cutting the trachea in the neck, and the health care professionals will slide the tube into the patient’s windpipe to control airflow.

Non-invasive ventilator: No cutting on the trachea. With a special ventilation mask which is connected with the tube, the non-invasive ventilator help the patient who is in shallow breath breathe.
