NON-INVASIVE EXERCISE TEST FOR COPD PATIENTS BY FG VISION SENSOR

运动对慢性阻塞性肺病患者的治疗很重要。采用FG视觉传感器对体表上的激光光斑进行分析，评价运动时的呼吸运动。使用FG传感器和呼出气体分析仪对健康受试者、哮喘患者和COPD患者进行斜坡工作试验。潮汐量、呼吸率和分钟量由FG传感器精确监测。该系统还可以观察到COPD患者在最大运动时呼气末水平升高，提示其在评估运动能力方面的实用性。

Exercise is important in the management of COPD patients. Respiratory movements during exercise with a cycle ergometer were evaluated by the analysis of laser spots beamed on the body surface with FG vision sensor. Ramp work test was performed in healthy subjects, asthmatics, and COPD patients with the FG sensor and an exhaled gas analyzer. Tidal volumes, respiratory rates, and minutes volumes were precisely monitored by the FG sensor. This system could also observe end-expiratory levels elevated at the maximum exercise in COPD patients, suggesting its usefulness in evaluating exercise capacity.
