An analysis on objectiveness of assessing symptom limited oxygen consumption (VO2SL) registered during exercise tests of increasing load of 30W every 3 minutes in 86 patients with chronic pulmonary diseases and 30 healthy control subjects. 36 did not have any ventilatory disorders, 50 had lowered ventilatory efficiency. VO2SL differed significantly in both study groups and the control. It was 1.80 L x min-1 in patients without ventilatory disturbances, 1.52 L x min-1 in patients with ventilatory disturbances and 2.12 L x min-1 in the control. The test was exceptable. In most of the subjects the results were repeatable, correlation indexes between the first and next assessment was 0.88, 0.95 and 0.83. Variance analysis did not differ between groups. The study demonstrated usefulness of VO2SL in determining exercise tolerance and in diagnosing patients with chronic pulmonary diseases.
对86例慢性肺部疾病患者和30名健康对照者进行递增负荷运动试验（每3分钟增加30W负荷）时记录的症状限制性耗氧量（VO2SL）评估的客观性分析。其中36人无任何通气障碍，50人通气效率降低。两个研究组与对照组的VO2SL差异显著。无通气障碍患者的VO2SL为1.80L·min⁻¹，有通气障碍患者为1.52L·min⁻¹，对照组为2.12L·min⁻¹。该测试是可接受的。在大多数受试者中结果具有可重复性，首次评估与再次评估之间的相关指数分别为0.88、0.95和0.83。组间方差分析无差异。该研究证明了VO2SL在确定运动耐力和诊断慢性肺部疾病患者方面的有用性。
