摘要

Background: Chronic obstructive pulmonary disease (COPD) is accompanied by a number of clinical symptoms, from cough and breathlessness to system disorders as a result of comorbidities. These manifestations have a significant effect on decreased exercise tolerance. Patients are limited in activities of daily living and in physical activities, especially walking, walking upstairs and uphill. Objective: The objective of this study was to assess exercise tolerance and compare the results of the Incremental shuttle walk test (ISWT) in patients with severe COPD and a group of healthy individuals. The next aim was focused on the changes in haemoglobin oxygen saturation during the test, Borg scale values and reasons for termination of the test. Methods: The research sample consisted of 17 patients (mean age 65.5?±?7.3?years) with severe COPD (post-bronchodilator forced expiratory volume in one second less than 60%). The group of healthy individuals consisted of 17 healthy individuals (mean age 62.6?±?2.0?years). The participants underwent ISWT. Throughout the whole test, saturation and heart rate were monitored using a finger oximeter recorder. Results: Patients with COPD covered a significantly shorter distance in ISWT (p?
