Ventilator

In a healthy person, breathing provides enough oxygen to keep our body well. But after surgery or an accident, the body is too tired or damaged and may need some help to breath. The machine that helps the patient breathe is called a ventilator. It moves oxygen (air) in and out of the lungs. A big tube goes from the ventilator to a tube in the patient's mouth. The tube in the mouth goes to the lungs. That's where the ventilator puts the oxygen (air). The patient can't eat or talk because of the big tube in their mouth. Sometimes the ventilator alarms make a lot of noise and red lights flash on the screen. When the patient is better and can breathe by themselves, the tube will be removed.
