Analysis of atelectasis, ventilated, and hyperinflated lung during mechanical ventilation by dynamic CT.

Study Objective: To study the dynamics of lung compartments by dynamic CT (dCT) imaging during uninterrupted pressure-controlled ventilation (PCV) and different positive end-expiratory pressure (PEEP) settings in healthy and damaged lungs.

Design: Experimental animal investigation.

Setting: Experimental animal facility of a university department.
