This invention describes a patient monitoring system which creates graphical displays of various pulmonary and other patient functions so that physicians and clinicians can quickly and accurately make decisions about the patient's care based on the graphical displays while in the intensive care unit. Patient functions are monitored and pulmonary models are implemented to graphically reveal relationships between the basic information input to the system from monitoring devices and the models so that physicians can utilize the revealed relationships to make informed accurate diagnoses and design therapeutic plans concerning the patient.

Intensive care information graphical display

A method and apparatus for unifying the pressure/flow and ventilation perfusion ratios is disclosed. The method comprises the following steps: determining the initial health condition of a patient so as to define a pulmonary pressure flow curve for each of a plurality of lung compartments of said patient; applying a stimulus of hypoxic pulmonary vasoconstriction to the pressure flow curve for each compartment to obtain a pressure flow curve for each of said plurality of compartments; and deriving a pulmonary artery pressure value corresponding to a ventilation/perfusion ratio that satisfies both the individual and total pressure flow requirements for said pulmonary pressure/flow curves.
