1. A method of operating a ventilator, comprising the steps of:
- providing a ventilator having a control device, the control device, including means for inputting data;
inputting, into the control device, data representing only the body length of a patient to be ventilated;
calculating, in the control device, at least one ventilation parameter based upon the input data, wherein aid at least one ventilation parameter includes a rate of rise of inspiratory parameter;
providing a first ventilated breath with a second rate of rise of inspiratory pressure;
providing a second ventilated breath with a second rate of rise of inspiratory pressure;
evaluating each of said ventilated breaths;
selecting the rate of rise that provides a desired pressure waveform; and
providing ventilation using said selected rate of rise.
