The Use of Computers in Physiologic Diagnosis

The major activity of this laboratory is to establish mathematical models that approximately describe the various parts of the cardiovascular and pulmonary systems. With this knowledge descriptive equations can be derived that are suitable for solution by computer techniques. These solutions are of potential diagnostic value. Two examples will be cited in which 1) blood velocity is computed from a measured pressure gradient and 2) the physical properties of certain intrathoracic pulmonary structures may be deduced from air flow measurement.
