title: Teaching the uptake and distribution of halothane. A computer simulation program.
abstract: A computer aided learning program for teaching the kinetics of uptake and distribution of the inhalational anaesthetic halothane is described. The program is based on a seven-compartment model which simulates the action of halothane on ventilation and on the cardiovascular system. The program is available to the student in four forms: one with no changes in circulation or respiration, one with the cardiovascular effects of halothane included, one with respiratory effects only, and one with both of these effects combined. The student can study the importance of the influence of halothane on respiration and blood circulation by comparing results from simulations on different models. The simulation is presented as graphs which are continuously displayed on an alphanumeric visual display terminal. Interaction with the program is possible at all times to change the simulation speed, the variables being graphed, the inspired halothane fraction, and the fresh gas flow.
