Comparison of the Two and Six- Minute Walk Tests in Evaluating Oxygen Desaturation in Patients With Severe COPD

NCT ID: NCT02462343

Last Updated: 2015-06-04

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 26 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2007-03-31
• Study Completion Date: 2007-08-31

Brief Summary

All measurements are performed on two consecutive days at the beginning of a pulmonary rehabilitation program in a randomized cross-over study design. On the first day, each patient is randomly assigned to perform either the 2 minute walk test or the 6 Minute walk test. On the second day each patient performs the test that was not performed on the first day. All walk tests are performed by the same investigator on the same track and time of day, following the 2002 guidelines of the American Thoracic Society.

Patients wear a mobile pulse oximeter that continuously records heart rate and oxygen saturation during testing. Baseline values of oxygen saturation, heart rate and ratings of perceived exertion on the modified Borg scale (0 to 10) for dyspnea and leg fatigue are recorded at rest after 10 minutes of sitting.
