| Abstract: | The respiratory control system is treated as linear with a transmission delay between ventilation and sensing points (chemoreceptors). To the accepted variables involving body gas stores, ventilatory effects, transmission effects, and steady state pH, P(CO2), P(O2) chemoreceptor response, certain detailed analysis of the central receptors have been added. By construction of a model for medullary CO(2) receptor utilizing expected values of CNS (central nervous system) circulation, CO(2) production, and tissue-buffering effects, results of experimental observation of the effects of alteration of CSF were simulated. The inclusion of CSF effects also allowed simulation of the response to alteration in inspired CO(2), hyperventilation, and the periodic breathing with prolongation of circulation time. |
