Effect of Breather in COPD Patients With Intermittent Claudication

recent researches show that COPD patients have risk of developing peripheral arterial disease (PAD) which represented on patient by intermittent claudication inspiratory muscle trainer as the breather device show increasing in inspiratory muscle strength and endurance; reduction of dyspnea; and improving of exercise tolerance .

Because of all this things this study tends to show the effect of the breather on ventilatory and vascular function in COPD patient with intermittent claudication.
