Figure 3From: Effects of sigh during pressure control and pressure support ventilation in pulmonary and extrapulmonary mild acute lung injury Volume fraction of the lung occupied by normal pulmonary areas, collapsed alveoli, and hyperinflated structures. Each bar represents the mean + standard deviation (SD) of six rats in each group. *Significantly different from PCV non-Sigh (P <0.05); **significantly different from PCV-Sigh (P <0.05); #significantly different from PSV non-Sigh (P <0.05). ALIexp, extrapulmonary acute lung injury; ALIp, pulmonary acute lung injury; NS, non-sigh; PCV, pressure-controlled ventilation; PSV, pressure support ventilation.Back to article page
