Cybernetics of cardiorespiratory synchrony

Characterization by Modulating the Respiratory Rate

Summary

The paper deals with the cybernetic system which tends to synchronize the respiratory rhythm with the cardiac rhythm. With anesthetized rabbits an experimental procedure has been worked out to test to what extent the system can maintain a synchrony, once established, against a disturbance of variable intensity. The disturbance consists of selectively driving the respiratory rate to increase continuously without altering the cardiac rate, the drive being accomplished by a special lung volume reflex.

The maintenance power of the cybernetic system was found to be the more effective the smaller the increment in respiratory rate, the correlation being hyperbolic.
