Figure 2From: Open lung approach with low tidal volume mechanical ventilation attenuates lung injury in rats with massive brain damagePolymerase chain reaction of lung tissue. All values are presented as median and 25% to 75% interquartile ranges. P-values above brackets showed significant difference (P <0.05). BD, brain damage; HVT/LPEEP, six hours of high tidal volume ventilation with low PEEP, no brain damage; LVT/OLPEEP, six hours of low tidal volume ventilation with open lung positive end-expiratory pressure; NBD, no brain damage.Back to article page
