Abstract :
Lung sounds and central airway flow were recorded during the slow reinflation of isolated dog lung lobes. The flow transients coincided with crackles or their bursts, which were rare and powerful before the mass recruitment of airspaces, but became more frequent and attenuated as the reopenings moved towards the periphery
