Reducing acute respiratory distress syndrome occurrence using mechanical ventilation

Figure 5 Histological comparison of a rat receiving early airway pressure release ventilation with a rat receiving volume cycled ventilation. The VC animal exhibits hallmarks of acute respiratory distress syndrome, including alveolar flooding (stars), fibrinous deposits in the air compartment (arrowheads) and high cellularity (between arrows). The APRV animal shows patent alveoli with notable preservation of nearly normal histology (with permission)[35]. APRV: Airway pressure release ventilation; VC: Volume cycled ventilation.
