The impact of noninvasive ventilation during the physical training in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD).
OBJECTIVE To evaluate the influence of physical training with or without noninvasive ventilation at 2 levels of pressure in the airways ( BiPAP ) in patients with chronic obstructive pulmonary disease . METHODS Eighteen patients with FEV(1 ) = 34 + /- 8 % of predicted values , mean age of 68 + /- 9 years were r and omly distributed into 2 groups , one group performing physical training on a treadmill and the other group performing physical training associated with BiPAP ( physical training+B ) , for 30 minutes , 3 times a week for 12 weeks . The training velocity was based on a test of cardiopulmonary force performed pre- and postintervention , which registered the values for heart rate , systolic blood pressure , diastolic blood pressure , peripheral oxygen saturation , blood lactate , sensation of dyspnea , respiratory muscle strength , and analysis of gases expired such as oxygen consumption and the production of carbon dioxide . RESULTS For both groups , there was a significant improvement in dyspnea and peripheral oxygen saturation at identical levels of physical exercise , in distance walked during the physical training , and in respiratory muscle strength ( P < 0.05 ) . Only the physical training+B group had a significant improvement in heart rate , systolic blood pressure , and oxygen consumption after training ( P < 0.05 ) . Significant reductions of blood lactate were observed at identical levels of exercise in physical training+B when compared to isolated physical training ( from 1.3 + /- 0.7 mMol/L versus 2.5 + /- 0.9 mMol/L , ( P < 0.05 ) , respectively ) . CONCLUSION Physical training associated with BiPAP enhanced the oxidative muscular capacity and could be an adjunctive recourse for physical rehabilitation in patients with chronic obstructive pulmonary disease
