论文摘要
本文考虑了基于手动复苏者袋（也称为Ambubag）的低成本呼吸机的控制设计，以将空气泵入身体无法呼吸的患者的肺部。首先，它通过实验表明，要准确跟踪潮汐量，控制器需要适应单个患者和不同的配置，例如硬件或操作模式。其次，它提出了一种设定的适应算法，该算法使用流量计的传感器测量值来自动将控制器调整到手头的设置中。第三，它通过实验表明，这种自适应解决方案可改善各种设置的呼吸机的性能。本文的一个目的是提高对使用低成本呼吸机解决方案中传感器测量的反馈控制需求的认识，以自动适应特定情况。
This paper considers the control design for a low-cost ventilator that is based on a manual resuscitator bag (also known as AmbuBag) to pump air into the lungs of a patient who is physically unable to breathe. First, it experimentally shows that for accurately tracking tidal volumes, the controller needs to be adapted to the individual patient and the different configurations, e.g., hardware or operation modes. Second, it proposes a set-point adaptation algorithm that uses sensor measurements of a flow meter to automatically adapt the controller to the setup at hand. Third, it experimentally shows that such an adaptive solution improves the performance of the ventilator for various setups. One objective of this paper is to increase awareness of the need for feedback control using sensor measurements in low-cost ventilator solutions in order to automatically adapt to the specific scenario.
