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.

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans. [PDF]
Exp PhysiolAbstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

The influence of metaboreflex activation on pulmonary pressure with combined chemoreflex activation in acute and chronic hypoxia. [PDF]
J PhysiolAbstract figure legend Activation of both the metaboreflex via post‐exercise circulatory occlusion and the chemoreflex via acute and chronic hypoxia increased pulmonary artery systolic pressure. Coactivation of these reflexes further increased pulmonary artery pressure in an additive manner.

When CO<sub>2</sub> sensing fails: Protective effects of sex hormones and potential mechanisms. [PDF]
J NeuroendocrinolAbstract Breathing movements driven by the brainstem rhythmogenic neural networks rely on chemosensory inputs to produce a motor output that is homeostatically adjusted to the prevailing metabolic demand. The central CO2 chemoreflex is a critical component of respiratory neural circuitry, as defects in these sensors cause hypoventilation syndromes ...

Chemoreflex adaptations to hypoxia [PDF]
, 2000 grantor: University of TorontoThis study investigates the role of hypoxia in the context of the chemical control of breathing in humans. A group of 7 volunteers were exposed to isocapnic (eucapnic) hypoxia for 20 minutes, once daily for 14 ...

Autonomic cardiovascular reflex control of hemodynamics during exercise in heart failure with reduced ejection fraction and the effects of exercise training [PDF]
Reviews in Cardiovascular Medicine, 2022 Heart failure with reduced ejection fraction is associated with increased exercise intolerance, morbidity, and mortality. Importantly, exercise intolerance in heart failure with reduced ejection fraction is a key factor limiting patient quality of ...

Exercise hyperpnoea: Unravelling layers of regulation. [PDF]
J PhysiolAbstract figure legend Intensity‐dependent changes in hypercapnic ventilatory response (HCVR) and feedforward gain (GEX) during exercise hyperpnoea below the respiratory compensation point (RCP). Participants (N = 20; 10 females) completed a 44 min step‐incremental cycling protocol in the moderate (below gas exchange threshold (GET)) and heavy ...
