A medical ventilator is a critical life-support device used to assist or fully control a patient’s breathing when they are unable to breathe adequately on their own due to illness, surgery, or respiratory failure. It delivers a regulated flow of oxygen-rich air into the lungs and helps maintain proper oxygen and carbon dioxide levels in the body.

Designed for use in intensive care units, emergency rooms, and critical care settings, modern ventilators offer advanced modes of ventilation, precise pressure and volume control, and real-time patient monitoring. They are essential in treating conditions such as acute respiratory distress syndrome (ARDS), pneumonia, chronic obstructive pulmonary disease (COPD), and during post-operative recovery.
