What is a ventilator? In very simple language, it is a machine that saves the life of patients who have trouble breathing or are unable to breathe themselves. If the lungs are unable to function due to illness, the ventilators handle the breathing process. Meanwhile, doctors make the lungs work again through treatment.
Types of ventilators: Ventilators are mainly of two types. First mechanical ventilation and second non-invasive ventilation. The tube of the mechanical ventilator is attached to the patient's windpipe, which carries oxygen to the lungs. The ventilator pulls out carbon dioxide from the patient's body and sends oxygen inside. The second type of ventilator is not attached to the windpipe, but rather a mask covering the mouth and nose is used to carry out this procedure.
Why is ventilator needed for corona patients? According to the World Health Organization (WHO), 80% of patients infected with COVID-19 recover without going to the hospital, but one in six patients become critical and have difficulty breathing. In such patients, the virus damages the lungs. The lungs fill with water makes it very difficult to breathe and the amount of oxygen in the body starts decreasing. Therefore ventilators are required. Through this, the amount of oxygen in the patient's body is normalized.
