Resumo OBJECTIVE: The aim of this study was to measure dynamic lung hyperinflation and its influence on dyspnea perception in moderate and severe chronic obstructive pulmonary disease patients after performing activities of daily living. METHODS: We measured inspiratory capacity, sensation of dyspnea, peripheral oxygen saturation, heart rate and respiratory rate in 19 chronic obstructive pulmonary disease patients. These measurements were taken at rest and after performing activities of daily living (e.g., going up and down a set of stairs, going up and down a ramp and sweeping and mopping a room). RESULT: The inspiratory capacity of patients at rest was significantly decreased compared to the capacity of patients after performing activities. The change in inspiratory capacity was -0.67 L after going up and down a ramp, -0.46 L after sweeping and mopping a room, and -0.55 L after climbing up and down a set of stairs. Dyspnea perception increased significantly between rest, sweeping and mopping, and going up and down a set of stairs. Dyspnea perception correlated positively with inspiratory capacity variation (r = 0.85) and respiratory rate (r = 0.37) and negatively with peripheral oxygen saturation (r = -0.28). CONCLUSION: Chronic obstructive pulmonary disease patients exhibited reductions in inspiratory capacity and increases in dyspnea perception during commonly performed activities of daily living, which may limit physical performance in these patients.
