Oxygen and ventilatory output during several activities of daily living performed by COPD patients stratified according to disease severity.

<h4>Objectives</h4>To measure the oxygen and ventilatory output across all COPD stages performing 18 common ADL and identify the activities that present the highest metabolic and ventilatory output as well as to compare the energy expenditure within each disease severity.<h4>Materi...
