MEDICAL VENTILATION SYSTEM

A medical ventilation system (1000), comprising an input device (10), a first gas source interface (11), a second gas source interface (12), a respiratory line (13), a drive gas branch (14), a fresh gas branch (15), and a ventilation controller (16). According to first mode control information received by the input device (10), the ventilation controller (16) controls the drive gas branch (14) to provide ventilation support for a patient through the respiratory line (13), and controls the fresh gas branch (15) to output anesthetic-containing fresh gas to the respiratory line (13); or according to second mode control information received by the input device (10), the ventilation controller (16) controls the drive gas branch (14) to output first gas to the respiratory line (13), and controls the fresh gas branch (15) to output second gas to the respiratory line (13). While maintaining a conventional anesthesia function of the medical ventilation system in the prior art, when a second mode is selected, a high-flow-rate oxygen supply function can be implemented, an existing pipe connecting manner does not need to be changed, and the complexity of a high-flow-rate oxygen supply device in the prior art is effectively reduced.
