Assessment of exercise tolerance in chronic bronchitis and interstitial lung disease. Journal of the Association of Physicians of India. 1993 Mar; 41(3): 144-6http://imsear.searo.who.int/handle/123456789/87621Cardiopulmonary exercise testing has a definitive place in objective evaluation of the subjective sensation of breathlessness. In the present study 21 patients with COPD, 10 with ILD and 17 normals were subjected to stage 1 exercise testing and correlations were sought between Vo2 and work, FVC, FeV1, Ve, respiratory rate and tidal volume and between VCO2 and work. In COPD and ILD the Vo2 correlated with work, Fev1, Fvc and Ve whereas in normals it correlated with the VE but not with the FeV1 and FVC. In COPD VO2 correlated with TV though this was not the case in ILD. Thus stage 1 exercise testing can be a useful additional method to assess the disability in COPD and ILD although differentiation between these two respiratory diseases on basis of exercise testing alone may not be possible.engAdultBronchitis --diagnosisDyspnea --diagnosisExercise TestFemaleHumansLung --physiopathologyLung Diseases, Interstitial --diagnosisLung Diseases, Obstructive --diagnosisLung Volume MeasurementsMaleOxygen --physiologyJournal Article
