About this trial
The aim of this study To show the effect of breather on ventilatory and vascular function in COPD patient with intermittent claudication.

Treatments tested in this trial
The BREATHER
DeviceThe BREATHER is Light/Medium resistance inspiratory muscle trainer which has significance role in increasing inspiratory muscle strength and endurance which could result in a decreased sensation of dyspnea
pharmacological treatment
Drugpatient will receive the usually pharmacological treatment.
Treatment groups
Trial outcomes
Primary outcomes
Ventilatory function: by spirometry test
Spirometry is a physiological test that measures the ability to inhale and exhale air relative to time.
Vascular function: by doppler ultrasound
Doppler ultrasound is a simple and non-invasive and method for the evaluation of early atherosclerosis. It can be used as a screening program for PAD in populations with high risk for atherosclerosis.
Secondary outcomes
Functional capacity assessment: by 5 repetitions sit to stand test (5R-STS)
(5R-STS) test is an objective test of functional impairment commonly used in various diseases including COPD which is used to measure the severity of disease and to monitor recovery.
Treadmill exercise testing
The results of the tests will be expressed in units of distance that will be walked up to the claudication pain (initial claudication distance) and the maximally tolerated claudication pain (maximal claudication distance).
