This Letter presents the implementation in a hardware device of the mean arterial pressure (MAP) response model of patients subjected to the infusion of the vasoconstrictor drug phenylephrine, enabling the development of automatic control systems in the future. The proposed model was firstly developed in a software platform with Simulink/MatLab using block libraries based on previous research carried out with animals and then implemented on hardware using a single-board computer with microcontroller and code generated in C/C++. The responses of MAP were simulated and compared using the proposed software and hardware model, considering the dynamic effects of several patients. The results showed that the hardware model presented 0.43% as the largest absolute percentage error observed in all trials, for an injection rate of the drug varying in steps with levels of 40 ml/h

去氧肾上腺素低血压患者平均动脉压实时模拟装置

这封信介绍了在接受血管收缩药物苯肾上腺素输注的患者的平均动脉压 (MAP) 响应模型的硬件设备中的实现，从而能够在未来开发自动控制系统。所提出的模型首先在具有 Simulink/MatLab 的软件平台上开发，使用基于先前对动物进行的研究的块库，然后使用带有微控制器的单板计算机和在 C/C++ 中生成的代码在硬件上实现。考虑到几名患者的动态影响，使用所提出的软件和硬件模型模拟和比较了 MAP 的反应。结果表明，硬件模型在所有试验中观察到的最大绝对百分比误差为 0.43%，
