  • Method and apparatus for unifying the ventilation/perfusion and pressure/flow models
    Patent number: 5606976
    Abstract: 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.
