[Let's study exponential function related to anesthesiology by using computer graphics--Part II: Wash-in exponential function].
The author first explained the wash-in exponential function. Then mathematically simulated changes in the concentration of inhalation anesthetic inside a breathing circle during induction of anesthesia were shown as a physical model related to anesthesiology to explain the idea of wash-in exponential function. Effect of the flow rate and concentration of anesthetic delivered to a breathing circle on the changes in the anesthetic concentration inhaled by patients was calculated and graphed by using a computer program developed for science education. The author also stressed the importance of graphic expression in understanding various physical or biophysical phenomena related to anesthesiology.
