RESUMO:
Chronic Obstructive Pulmonary Disease (COPD) is a common, preventable and treatable disease characterized by persistent respiratory symptoms and airflow limitation due to changes in the airways and alveoli caused by significant exposures to harmful particles and gases. Airflow limitation can reduce the patient's expiratory capacity, resulting in pulmonary hyperinflation, which, when there is a high ventilatory and metabolic demand, is called dynamic hyperinflation (HD). Expiratory Positive Airway Pressure (EPAP) could have the potential to minimize or prevent HD. It is now possible to more accurately measure the effect of EPAP on HD through Optoelectronic Plethysmography (POE). Objectives: The aim of this study is to evaluate the acute effects of EPAP on HD in patients with COPD who underwent physical exercise. Methodology: 18 patients were recruited, 4 were excluded, totaling a final sample of 14 patients (7 men and 7 women). This is an observational cross-over, cross-over study with patients with clinical diagnosis of COPD and moderate to severe airflow obstruction. The patients were evaluated in three moments; moment 1: pulmonary function, respiratory muscle strength, Human Activity Profile (PAH), Medical Research Council (MRC) Scale, Incremental Shuttle Walking Test (ISWT); and at moments 2 and 3: chest wall volumes (POE) during the exercise protocol with constant load with and without the use of EPAP, with resistance graded at 7.5 cmH2O in a random order. Results: In intragroup analyzes, a significant increase in the volumes of all chest wall compartments was observed in the EPAP group, and only in the abdominal compartment (Rib cage abdominal - Rca) and Abdomen (Abdomen - Ab) compartments in the placebo group during exercise . There was a statistically significant decrease in inspiratory (Ti), expiratory (Te) and total time (Ttot) times during exercise in the placebo group, and a significant increase in index of shortening velocity of inspiratory and expiratory muscles in both the EPAP and placebo groups during exercise. In the intergroup analyzes we observed a significant decrease in the times (Ti, Te and Ttot) in the placebo group, in addition to the significant decrease in diaphragm index of shortening velocity (ΔVab / Ti) in the EPAP group. Additionally, we obtained a lower total exercise time and a higher dyspnea (BORG) at the end of the exercise in the EPAP group. Conclusion: The use of EPAP during exercise did not promote reduction in the development of HD.
