CO2 chemoreflex contributions to ventilatory long‐term facilitation

The Journal of Physiology, EarlyView.
Abstract figure legend To determine whether changes in CO2 chemoreflex sensitivity contribute to ventilatory long‐term facilitation (LTF), we tested the hypothesis that hypercapnic acute intermittent hypoxia (AIH) induces ventilatory LTF and enhances peripheral, but not central, chemoreceptor CO2 chemoreflex sensitivity.

Electrophysiological properties of the dorsal motor nucleus of the vagus motoneurones controlling airway mucus secretion in rats

The Journal of Physiology, EarlyView.
Abstract figure legend Acidosis depolarises parasympathetic respiratory motoneurones in the dorsal motor nucleus of the vagus (DMV) and increases their firing frequency by reducing TWIK‐2 channel conductance. Acidosis also activates astrocytes, which further enhance neuronal excitability through NMDA receptor‐dependent glutamatergic signalling.

Altitude‐induced plasticity of respiratory central–peripheral chemoreflex interaction

The Journal of Physiology, EarlyView.
Abstract figure legend Altitude‐induced plasticity of respiratory central–peripheral chemoreflex interaction. Seventeen participants completed modified rebreathing tests at low altitude and after 7–10 days of acclimatization at high altitude (3500 m). Central chemoreceptor activation was isolated using hypercapnic hyperoxia (end‐tidal PO2${{P}_{{{O}_2}}

Respiratory Support With Nasal High Flow Reduces Opioid Requirements During Endoscopic Retrograde Cholangiopancreatography

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Nasal high flow (NHF) improves oxygenation, reduces the work of breathing, and stabilizes ventilation. In endoscopic retrograde cholangiopancreatography (ERCP) under dexmedetomidine‐based sedation, opioids are often required but increase the risk of respiratory depression and delayed recovery.
