In a previous study, we successfully used a target feedback device, together with an external resistor, to train the ventilatory muscles of patients with chronic obstructive pulmonary disease. In this article, we describe the details of the design and function of the target feedback device. When used in conjunction with an external resistance, the target feedback device provides timing and pressure targets, together with feedback information, on whether these targets are achieved. The target feedback device consists of readily available electronic components and is relatively simple to construct. Adjustment of an external pressure knob permits setting of pressure targets. Adjustment of internal components is possible and allows control of breathing frequency, inspiratory time, and breathing waveform.
在先前的一项研究中，我们成功地使用了一种目标反馈装置，连同一个外部电阻，来训练慢性阻塞性肺疾病患者的呼吸肌。在本文中，我们描述了该目标反馈装置的设计细节和功能。当与外部阻力配合使用时，目标反馈装置会提供时间和压力目标，以及关于这些目标是否达成的反馈信息。该目标反馈装置由易于获得的电子元件组成，构造相对简单。通过调节外部压力旋钮可以设置压力目标。内部元件也可以进行调节，从而控制呼吸频率、吸气时间和呼吸波形。
