## Abstract

An input device for a clinician to control and modify the operation of a mechanical ventilator comprises a graphical display, a representation of a respiratory therapy trajectory to be delivered to a patient, at least one data point associated with the trajectory, and a data input means for the clinician to select a data point and to modify the value of the trajectory at that data point. The present invention provides for the creation and modification of a respiratory therapy trajectory, wherein the ventilator provides a medical gas waveform to a patient according to the respiratory therapy trajectory.
