in 11 spontaneously breathing patients with chronic obstructive pulmonary disease ( copd ) in acute ventilatory failure , we measured the total inspiratory ( witot ) and total resistive ( wi + eres ) work rate of breathing , together with lung mechanics ( dynamic pulmonary elastance and inspiratory and expiratory pulmonary flow resistance ) .
