Six minutes walking test, 6MWT
dyspnea, fatigue
BLOOD, THORACIC
The 6MWT was undertaken in accordance with the American Thoracic Society (ATS)/European Respiratory Society (ERS) guidelines. It was carried out by the team members in the corridor of the respiratory ward of the hospital, with a length of 30 m and red warning lines marked at both ends of the ground. Blood oxygen saturation and heart rate were monitored during the experiment using a portable oximeter. At the end of the experiment, walking distance was recorded, and the Borg scale was used to assess dyspnea and fatigue.
