3. Why do doctors use mechanical ventilation?Doctors use it when a person has trouble breathing because of illnesses like pneumonia, lung injury, or after surgery. The machine keeps the blood oxygen-rich and removes extra carbon dioxide.
4. How does mechanical ventilation work?The machine pushes air into the lungs, either through a tube in the throat or a mask on the face. It can control how much air and how fast it is moved, just like a breathing assistant.

Positive Pressure Ventilation: A method where a machine actively pushes air into the lungs through the patient's airway.
Negative Pressure Ventilation: A method where the chest cavity is expanded externally, causing air to be drawn into the lungs.
Tidal Volume: The amount of air that moves in or out of the lungs during a single breath.
Ventilator-Associated Pneumonia (VAP): A lung infection that can develop in patients receiving mechanical ventilation.
