What this Trial Is About

This trial investigates the effect of the Breather device on breathing and blood vessel function in male patients aged 55 to 60 with chronic obstructive pulmonary disease (COPD) and intermittent claudication caused by peripheral arterial disease (PAD). Research shows that COPD patients are at risk of developing PAD, which causes leg pain during walking. The Breather is an inspiratory muscle trainer that may improve breathing muscle strength, reduce breathlessness, and enhance exercise tolerance in these patients. Participants will receive treatment with the Breather device, which provides light to medium resistance to strengthen breathing muscles and potentially decrease breathlessness. They will also continue their usual pharmacological treatments. The study focuses on evaluating how this device affects breathing and vascular function. During the study, participants will undergo tests including spirometry to measure lung function and Doppler ultrasound to assess blood vessel function after four weeks of using the Breather. Researchers will monitor these outcomes to understand the device's impact on breathing and circulation. The study includes 60 male patients who are clinically stable and meet specific criteria related to COPD severity, body weight, and symptoms of intermittent claudication.
