Gas Man Simulates Correct Alveolar Plateaus and Quantifies Overpressure for Desired Alveolar Tension
Gas Man® is a computer simulation1 which uses pictorial and graphical displays to depict anesthetic tension in various compartments representing locations in the anesthesia gas machine, breathing circuit, and patient See Figure 1. The simulation solves the simultaneous differential equations that govern the behavior of the five-compartment model. The model structure knows nothing of exponentials but calculates these and other curves in response to step changes in input variables (vaporizer setting and fresh gas flow) or model parameters (cardiac output and alveolar ventilation)
