Medical students in Germany do not usually have a strong enough basis in physics to understand the mechanical and fluid dynamic problems involved in the physiology of the circulation. To alleviate this situation we developed a circulation model for use in laboratory courses in physiology. The following parameters can be varied: stroke volume, heart rate, systemic filling pressure, compliance of the arterial system (Windkessel), and total peripheral resistance. Arterial and venous pressure are recorded as a function of time. The following points are worked out by the students by adjusting the parameters of the model and by calculation: static equilibrium, transient and steady state in flow, compliance of the arterial and venous system, arteriovenous pressure difference, cardiac output, total peripheral resistance, regulation of cardiac output, pulse pressure amplitude, volume stored periodically in the arterial Windkessel, diastolic pressure decay of arterial pressure, diagnosis of arterial hypertension at different Windkessel compliances.
德国的医科学生通常没有足够坚实的物理学基础来理解循环生理学中涉及的机械和流体动力学问题。为了改善这种情况，我们开发了一种用于生理学实验课程的循环模型。可以改变以下参数：每搏输出量、心率、体循环充盈压、动脉系统（风箱）的顺应性以及总外周阻力。动脉压和静脉压作为时间的函数被记录下来。学生们通过调整模型参数并进行计算来得出以下要点：静态平衡、血流的瞬态和稳态、动脉和静脉系统的顺应性、动静脉压差、心输出量、总外周阻力、心输出量的调节、脉压幅度、动脉风箱中周期性储存的容积、动脉压的舒张压下降、不同风箱顺应性下的动脉高血压诊断。
