Control-system for medical ventilator

摘要

A ventilator control system (10) controls a ventilator pneumatic system (18) in a medical ventilator. The ventilator control system (10) includes a user interface (26), a memory (40) and a processor (22). The user interface receives input values from a user for setting one or more breath parameters within a set of breath parameters. The user interface (26) can include a display (24) for displaying the status of the patient's pulmonary system and the set of breath parameters. The memory (40) stores the set of breath parameters after the user has set one or more breath parameters to desired input values. The processor (22) simultaneously adjusts a plurality of controls within a ventilator pneumatic system (18) in response to the set of breath parameters. The user can change or implement new phases, breaths, modes or therapies in seconds such that the therapy delivered to the patient (20) is essentially uninterrupted. Also, a simulator (212) may be provided for predicting the status of the patient's pulmonary system prior to adjusting the plurality of controls. The predicted status may be displayed adjacent the current status on the display (24).
