Abstract:
1. In a system for programming a respirator for ventilating a patient, the system including a programmable controller responsive to selected ventilation parameters for controlling the respirator to ventilate the patient and for storing a plurality of ventilation parameters, a display for displaying a plurality of implemented ventilation parameters currently used by the controller to control the respirator and a plurality of proposed but not implemented ventilation parameters, and an input system cooperating with the controller and the display for selecting one of the proposed but not implemented ventilation parameters from the plurality of proposed but not implemented ventilation parameters, the improvement comprising: said display including a graphical representation of the effect of the proposed but not implemented ventilation parameters on a breath cycle having a duration; wherein said graphical representation includes a time scale associated with the breath cycle, an inspiration bar having a length corresponding to a proposed inspiration time, an expiration bar having a length corresponding to a proposed expiration time, a first numerical indicator indicating the proposed inspiration time, a second numerical indicator indicating the proposed expiration time, and a third numerical indicator indicating the duration of the complete breath cycle, wherein at least the first and second numerical indicators are separate from the time scale.
