Hiperinsuflação dinâmica em pacientes com doença pulmonar obstrutiva crônica durante a realização de exercícios de membros superiores e membros inferiores

Abstract

During the exercise, there is an increased ventilatory demand in patients with Chronic Obstructive Pulmonary Disease (COPD), consequently there is an increase in air trapping and it is associated with decreased inspiratory capacity (IC) and dynamic hyperinflation (DH). Dynamic hyperinflation (DH) is a phenomenon demonstrated by measurement of lung volumes in patients with COPD while performing physical activities. The ventilation mechanisms may contribute to the limitation of physical activities and also activities of daily living (ADLs) such individuals, leading to functional limitations and physical deconditioning. The aim of this study was to evaluate, through a literature review, dynamic hyperinflation in patients with Chronic Obstructive Pulmonary Disease during exercises upper limb (UL), exercises of lower limbs (LL), ADL and Rehabilitation.The literature review was performed in Medline / PubMed, SciELO, LILACS, Cochrane and Peter from the first record until July 2012. The keywords used in the search in the databases were as follows: exercise, exercise Arm, upper limb exercises, training exercises, leg exercise, hyperinflation and COPD. To be included, studies must have as one of the outcomes evaluation of dynamic pulmonary hyperinflation in patients with COPD undergoing exercises in general (exercises for upper limbs, lower limbs, ADLs, etc). Eight (8) articles were selected and evaluated, they were published in English and Portuguese, from 2002 to 2012.Based on studies examined, it is concluded that during the ADL, exercise, and during pulmonary rehabilitation there is a decrease in CI, indicating an increase in HD, namely increased air trapping in COPD patients. However this finding, pulmonary rehabilitation is indicated for these individuals and is safe and well tolerated, resulting in decreased dyspnea and increased functionality of these patients.
