Abstract
The invention is directed to a ventilation control system for controlling the ventilation of a patient. The ventilation control system utilizes a user-friendly user interface for the display of patient data and ventilator status. The user interface includes a graphic representation of a breath cycle that displays the breath cycle currently being ventilated, and is also responsive to changes in ventilation settings to assist the user in evaluation the effect of those changes on the ventilator strategy before the changes are implemented.

49. A computer-implemented display for a breathing assistance device, comprising:
-
a graphical representation of a time scale for indicating data regarding a breath cycle, the breath cycle including an inspiration portion having an inspiration duration and an exhalation portion having an exhalation duration;
an inspiration graphic displayed relative to the time scale, the inspiration graphic comprising a graphical, non-numeric representation of the inspiration duration;
a representation of a calculated measure of the inspiration duration relative to the exhalation duration; and
a numeric representation of the inspiration duration distinct from the calculated measure of the inspiration duration relative to the exhalation duration.
