Artificial ventilation - Definition

Ask a question


Artificial ventilation is the process that enables a person's respiratory function to be carried out by a machine when they are unable to perform it alone, when in a coma, or when suffering from advanced chronic respiratory failure. The patient's respiratory function is carried out by inhalation and exhalation, allowing for the necessary gaseous exchanges to take place and the blood and cells to be supplied with oxygen. When these functions are performed insufficiently or not at all, respiratory function is maintained by a device that blows air at different pressures to ensure the gaseous exchange.
