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.
作者首先解释了吸入指数函数。然后，通过与麻醉学相关的物理模型展示了麻醉诱导期间呼吸回路内吸入麻醉剂浓度的数学模拟变化，以解释吸入指数函数的概念。利用为科学教育开发的计算机程序，计算并绘制了输送到呼吸回路的麻醉剂流速和浓度对患者吸入麻醉剂浓度变化的影响。作者还强调了图形表达在理解与麻醉学相关的各种物理或生物物理现象中的重要性。
