Effects of positive end-expiratory pressure on oscillated volume during high frequency chest compression in children with cystic fibrosis.

Objective: To investigate the effects of positive end-expiratory pressure (PEEP) on end-expiratory lung volume (EELV) and mean oscillated volume (V(osc)) during high frequency chest compression (HFCC).

Design: A clinic-based prospective intervention study.

Setting: Pulmonary function laboratory, University of Alberta, Edmonton, Alberta.
