ABSTRACT:
A ventilator control system controls a ventilator pneumatic system in a medical ventilator. The ventilator control system includes a user interface, a memory and a processor. 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 can include a display for displaying the status of the patient's pulmonary system and the set of breath parameters. The memory stores the set of breath parameters after the user has set one or more breath parameters to desired input values. The processor simultaneously adjusts a plurality of controls within a ventilator pneumatic system 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 is essentially uninterrupted. Also, a simulator 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.
