How do ventilators work
- The ventilator is a closed circuit that is attached to an endotracheal tube in the patient’s airway;
- on inhalation, the oxygen-rich air moves from the ventilator to a heat moisture exchanger where the air is heated and humidified to simulate.
- Natural air is then forced into the lungs, following the same route as that of normal breathing.

Ventilators are medical machines that help patients breathe. They both push oxygen into the lungs and remove carbon dioxide. The air enters the lungs through a breathing tube, with one end hooked up to the machine and the other going through the mouth or nose down to the windpipe. The procedure to put the tube in is called intubation.

How Does a Ventilator Help a Person Breathe?
Invasive ventilators gently force normal air (or a mixture of air and added oxygen) through a breathing tube, into a patient’s airways and down into their lungs. Mechanical ventilation not only ensures that a patient receives sufficient oxygen but also helps move carbon dioxide, a waste gas, out of the lungs. A person who cannot breathe efficiently on their own may retain carbon dioxide in the body, which can accumulate and reach toxic levels.
What is a ventilator?
