Abstract
One of the factors causing dyspnoea in COPD patients is dynamic hyperinflation which could on its turn limit daily physical activity. However, few studies have investigated if there is a relation between daily activity and dynamic hyperinflation. Our main objectives were to investigate the relationships between daily physical activity and dynamic hyperinflation induced by metronome-paced tachypnea, in terms of 1) development rate and recovery rate of dynamic hyperinflation and 2) the degree of dynamic hyperinflation, in patients with COPD. 35 patients with stable COPD were included. Daily physical activity was assessed using a 3Daccelerometer. Subjects underwent metronome-paced tachypnea and inspiratory capacity manoeuvres. In the quantification of the degree of dynamic hyperinflation, the change in the inspiratory capacity as a percentage of the total lung capacity was used to correct for body height. No significant correlations were found between daily physical activity and the parameters 1) and 2) as mentioned above. Although we did not find any relation between dynamic hyperinflation and daily physical activity, static hyperinflation could be a useful marker to indicate reduced daily physical activity.
