The Effect of a Modified Constant Flow Insufflation of Oxygen during Cardiopulmonary Resuscitation in a Rat Model of Respiratory Cardiac Arrest on Arterial Oxygenation, Alveolar Barotrauma, and Brain Tissue Injury

Figure 4

Histologic staining of lung tissue with haematoxylin-eosin 48 hours after the return of spontaneous circulation. Alveolar wall thickening was greater in the IPPV group than in the CFIO group, and there were more inflammatory cells. White arrows are pointing at inflammatory cells, and white circles indicate thickening of the alveolar wall. IPPV, intermittent positive pressure ventilation; CFIO, continuous flow insufflation of oxygen.
