Patterns of disturbed lung function in patients with chronic obstructive vesicular emphysema

In a previous publication (Ogilvie, 1959) an account was given of the functional disturbance in emphysematous patients without radiologically visible bullae. The purpose of this second paper is to describe the patterns of pulmonary dysfunction in 14 patients with pulmonary bullae and to compare these with the patterns observed in emphysematous patients without bullae. These patients were unselected in that they represented 14 consecutive referrals to the pulmonary function laboratory at the London Hospital. The methods used for measurement of lung function were those described previously (Ogilvie, 1959). Baldwin, Harden, Greene, Cournand, and Richards (1950) described 16 patients with larg
