What is mechanical ventilation?

• A. Machine assists or replaces breathing
• B. A device to monitor heart rate
• C. A therapy to improve oxygen carrying capacity
• D. A method to apply positive airway pressure

Answer: (A)

Mechanical ventilation means using a machine to deliver breaths to the lungs, taking over or supporting natural breathing. The ventilator can control things like how often you breathe, how much air is given with each breath, and the pressure or oxygen concentration in the air delivered. It can be used invasively through a tube into the airway or noninvasively with a mask. This is different from merely monitoring heart rate or trying to boost the blood’s oxygen-carrying capacity. While many ventilation modes involve maintaining airway pressure (positive airway pressure), the key idea is that a machine is actively delivering breaths to support breathing.
