Effects of Expiratory Positive Airway Pressure on Exercise Tolerance, Dynamic Hyperinflation, and Dyspnea in COPD.

Introduction: The application of expiratory positive airway pressure (EPAP) in patients with COPD during exercise may reduce dynamic hyperinflation, while, on the other hand, it can increase the resistive work of breathing. Therefore, we evaluated the effects of 2 intensities of EPAP during exercise on tolerance, dynamic hyperinflation, and dyspnea in subjects with moderate to very severe COPD.

Methods: We performed a cross-sectional, experimental, 4-visit study.

Cytokine response to the 6-min walk test in individuals with different degrees of COPD.

Background And Aim: Physical exercise is a key part of rehabilitation programs in chronic obstructive pulmonary disease (COPD) patients, although it could modulates immune system responses by altering the cytokine profile of such individuals. Furthermore, the degree of severity of COPD could influence the inflammatory response induced by exercise. To evaluate the cytokine profile of individuals with different degrees of COPD in response to a 6-min walk test (6MWT).

Effect of exercise performed during hemodialysis: strength versus aerobic.

Rational: Patients under regular dialysis can also present alterations in the cardiovascular, musculoskeletal, and metabolic systems.

Materials And Methods: Randomized clinical trial.

[Effects of aerobic exercise during haemodialysis in patients with chronic renal disease: a literature review].

Introduction: Patients with chronic kidney disease (CKD) have reduced physical and functional capacity when compared with the general population. Hemodialysis (HD) restricts patients activities, favoring a sedentary lifestyle and leading to functional limitations. HD patients are less active, present low exercise tolerance and have high physical deconditioning.

Effects of expiratory positive airway pressure on dynamic hyperinflation during exercise in patients with COPD.

Background: Expiratory positive airway pressure (EPAP) is a form of noninvasive positive-pressure ventilatory support that, in spite of not unloading respiratory muscles during inspiration, may reduce the inspiratory threshold load and attenuate expiratory dynamic airway compression, contributing to reduced expiratory air-flow limitation in patients with COPD. We sought to determine the effects of EPAP on operational lung volumes during exercise in COPD patients.

Methods: This was a nonrandomized, experimental comparison of 2 exercise conditions (with and without EPAP); subjects completed a treadmill exercise test and performed, before and immediately after exercise, lung volume measurements.
