Despite the magnitude of the public health problem presented by respiratory diseases, there have been few studies concerned with vocational rehabilitation (VR) potential of patients with chronic obstructive pulmonary disease (COPD). Certain physiologic variables which show a high degree of relationship to VR success are identified. The three independent variables which most highly correlate with the VR potential of patients with COPD are the percentages predicted for the first-second forced expiratory volume (FEV(1.0)), forced expiratory flow between 25 and 75 percent of the forced vital capacity (FEF(25-75 percent)), and maximum voluntary ventilation (MVV). The mean "cutting" percentages for inclusion in VR programs were 50, 27, and 40, respectively. The emotional variables studied do not differentiate potential VR success or failure as clearly as the physiologic factors. The criteria set forth not only can be used by rehabilitation workers but could serve as a basis for future demonstration studies.
尽管呼吸系统疾病所呈现的公共卫生问题规模巨大，但关注慢性阻塞性肺疾病（COPD）患者职业康复（VR）潜力的研究却很少。确定了某些与VR成功高度相关的生理变量。与COPD患者VR潜力相关性最高的三个独立变量是第一秒用力呼气量（FEV(1.0)）、用力肺活量25%至75%之间的用力呼气流量（FEF(25 - 75%)）以及最大自主通气量（MVV）的预测百分比。纳入VR项目的平均“临界”百分比分别为50%、27%和40%。所研究的情绪变量不像生理因素那样能清晰地区分VR潜在的成功或失败。所提出的标准不仅可供康复工作者使用，还可为未来的示范研究提供基础。
