A mechanical ventilator is a medical device used to provide respiratory support. It delivers a mixture of air and oxygen at specific pressure, volume, or frequency to the lungs, helping patients with impaired or absent breathing to receive oxygen and regulate the elimination of carbon dioxide. Mechanical ventilators are typically used through invasive methods (such as endotracheal tubes or tracheostomy) or non-invasive methods (such as face masks or CPAP). They play a crucial role in intensive care units (ICUs) for treating respiratory failure, recovery after surgical procedures, and certain acute conditions. Mechanical ventilators are critical devices that help sustain and improve the health of patients.
