Stimulating olfactory epithelium mitigates mechanical ventilation-induced hippocampal inflammation and apoptosis.

Mechanical ventilation (MV), as a life-saving procedure in critical patients, is a risk factor to develop of neurocognitive dysfunction and triggers of inflammation and apoptosis in the brain. Since diversion of breathing route to the tracheal tube diminishes brain activity entrained by physiological nasal breathing, we hypothesized that simulating nasal breathing using rhythmic air-puff (AP) into the nasal cavity of mechanically ventilated rats can reduce hippocampal inflammation and apoptosis in association with restoring respiration-coupled oscillations. We found that stimulating olfactory epithelium through applying rhythmic nasal AP, in association with reviving respiration-coupled brain rhythm, mitigates MV-induced hippocampal apoptosis and inflammation involving microglia and astrocytes.
