Results of simulation of non-homogeneous ventilatory mechanics for a patient-computer arrangement

A model of the ventilatory mechanic system was realised on the MEDA TC 41 analogue computer; it consists of 2 structurally identical compartments, differing in the values of their coefficients. By changing the values of coefficients and the relations between the 2 compartments, it was possible to simulate the non-homogeneity of a real, pathologically-changed system of the body afflicted by disease. Complex resistance loops with phase shifts. identical with those really registered from patients, were realised; this was impossible for models with only 1 compartment. By changing the non-homogeneity of the model., it was possible to simulate the past and future development of the state of the diseased patient with sufficient reliability.
