Keywords: 6 minutewalk test, COPD, respiratory rate, dyspneascore, FEV1

Aim: Sixminute walk test (6MWT); is an execise test used as an indicator of the functional capacity in patients with cardio pulmonary disease. In this study, weaimed toin vestigate the relation between vital signs, bloodgasvalues, dys pneas core and walk distance in cases with severe COPD.

Materials And Methods: 6 minute walk test performedto 83 cases in stable period with severe and very severe COPD according to GOLD criteria. Dys pneas corese valuated with modified borgs cale. Lung function test performed before walking. Blood gas values and vital signs measured before and after test. Results compared with wil coxansigne drank test. Factor saffecting walk distance evaluated with lineer regression analysis.

Results: 83 cases completed the walking. Themost common complaint was dyspnea. Meanvalue of FEV1 in stableperiod of disease was 1,65 lt. Mean walk distance was 246m. Pulse rate, sys tolicand diastolic pressure, respiration rate and dys pneascore in creased after the walk test (p<0.005). pCO2 decreased significantly after the walk test(p<0.005) where as pO2 did not(p>0.005). Respiration rate and dys pneascore was found as the factor saffecting the walk distance

Conclusion: In this study, we have seen, walk distance in dependent fromage, sex, FEV1 value but respiration rate and dys pneas core were found as factors affecting the determination of walk distance. Before the test, we can predict how far our patients with severe COPD can walk by looking at the respiratory rate and dyspnea score. If the distance is below the predicted value, we can repeat the test.
