What is a ventilator and what does it do?

According to the World Health Organization, about 80% of people with COVID-19 infection can recover without the need for hospital treatment.

But in six people only one person becomes seriously ill and can experience difficulty in breathing.

Even in severe cases, the virus causes damage to the lungs. The body’s immune system detects this and expands the bloodstream to allow more immune cells to enter.

But, unfortunately, this can cause fluid to enter the lungs, making it more difficult to breathe, and causing lower levels of oxygen.

According to the BBC, ventilator machines are important to use to overcome this kind of case. It is used to raise air, with increasing oxygen levels, into the lungs.

Ventilation also has a humidifier, which modifies the addition of heat and moisture to the medical air to match the patient’s body temperature.

Patients will be given medication to relax their respiratory muscles so that their breathing can be fully controlled by the machine.

While ventilation machines important for people with heavier symptoms, people with milder symptoms can be given ventilation using facemasks, nasal masks or mouthpieces that allow pressurized air or a mixture of gas to be pressed into the lungs.
