Abstract Purpose: The present study was conducted to study the 2-min walk test and 15-step
exercise oximetry test in determination of exercise tolerance in Egyptian patients with chronic
obstructive pulmonary disease.
Methods: Sixty male patients with COPD were included in this study who were divided into
three groups (mild, moderate and severe). All of the patients were subjected cardio pulmonary exercise
test using ramp protocol, 6 min walk test, 2-min walk test and 15 step exercise oximetry test.
Results: In this study we found significant difference between mild, moderate and severe groups as
regards VO2%predicted, distance walked during 6-MWT, distance walked during 2-MWT, and saturation
difference % and exercise time/s during 15-step exercise oximetry test (p value 0.05 for all).
Conclusions: The study shows that the 2MWT is a valid test for the assessment of exercise capacity
in patients with COPD. It is practical, simple, and well-tolerated by patients with severe COPD. |
