The Effect of Mechanical Ventilation on TASK-1 Expression in the Brain in a Rat Model

Figure 2

Representative images of lungs in each group after haematoxylin and eosin staining and associated LISs. Lung tissue of the MV group showed obvious damage, including significant alveolar oedema, haemorrhage, inflammatory cell infiltration, alveolar septal thickening, and alveolar overexpansion or atelectasis. LIS increased with MV and was significantly higher in the HVt group compared with that in the LVt group. Results are represented as the mean ± SD. versus the basal group. animals per group. MV, mechanical ventilation; BAS, basal; LVt, low tidal volume; HVt, high tidal volume; LIS, lung injury score.
