Early changes in lung gene expression due to high tidal volume.


The purpose of this study was to use gene expression profiling to understand how adult rat lung responds to high tidal volume (HV) ventilation in vivo. HV ventilation for 30 minutes did not cause discernable lung injury (in terms of altered mechanics or histology) but caused obvious injury when continued for 90 minutes. However, at 30-minute ventilation, HV… (More)
