Abstract

A system for receiving one or more measured physiological parameters of a patient and displaying a graphical representation of the same. In various embodiments, a display module generates a graphical display that includes a range of possible values for the physiological parameter, one or more thresholds and/or alarm values, a numeric display of the current value of the measured physiological parameter, and a historical comparator of the current value with historical values.
