Intubation: The process of putting a tube into a hollow organ or passageway, often into the airway. The opposite of intubation is extubation.

Mechanical ventilation: Use of a machine called a ventilator or respirator to improve the exchange of air between the lungs and the atmosphere.

Medical school: A school with a curriculum leading to a medical degree. The mission of every medical school includes medical teaching, research, and patient care.

Always contact your nearest Poison Control Center if you are concerned about possible poison ingestion.
