Integration of cerebrovascular CO2 reactivity and chemoreflex control of breathing: mechanisms of regulation, measurement, and interpretation

PN Ainslie, J Duffin - American Journal of Physiology …, 2009 - journals.physiology.org
Cerebral blood flow (CBF) and its distribution are highly sensitive to changes in the partial
pressure of arterial CO2 (PaCO2). This physiological response, termed cerebrovascular …

Interaction between the ventilatory and cerebrovascular responses to hypo‐and hypercapnia at rest and during exercise

S Ogoh, N Hayashi, M Inagaki… - The Journal of …, 2008 - Wiley Online Library
Cerebrovascular reactivity to changes in the partial pressure of arterial carbon dioxide (P)
via limiting changes in brain [H+] modulates ventilatory control. It remains unclear, however …

Neural control of breathing and CO2 homeostasis

PG Guyenet, DA Bayliss - Neuron, 2015 - cell.com
Recent advances have clarified how the brain detects CO 2 to regulate breathing (central
respiratory chemoreception). These mechanisms are reviewed and their significance is …

Human cerebrovascular and ventilatory CO2 reactivity to end‐tidal, arterial and internal jugular vein PCO2

K Peebles, L Celi, K McGrattan, C Murrell… - The Journal of …, 2007 - Wiley Online Library
This study examined cerebrovascular reactivity and ventilation during step changes in CO2
in humans. We hypothesized that:(1) end‐tidal P (P) would overestimate arterial P (P) during …

Influence of cerebrovascular function on the hypercapnic ventilatory response in healthy humans

A Xie, JB Skatrud, B Morgan, B Chenuel… - The Journal of …, 2006 - Wiley Online Library
An important determinant of [H+] in the environment of the central chemoreceptors is
cerebral blood flow. Accordingly we hypothesized that a reduction of brain perfusion or a …

Central CO2 chemoreception and integrated neural mechanisms of cardiovascular and respiratory control

PG Guyenet, RL Stornetta… - Journal of applied …, 2010 - journals.physiology.org
In this review, we examine why blood pressure (BP) and sympathetic nerve activity (SNA)
increase during a rise in central nervous system (CNS) Pco2 (central chemoreceptor …

Plasticity of Central Chemoreceptors: Effect of Bilateral Carotid Body Resection on Central CO2 Sensitivity

A Dahan, D Nieuwenhuijs, L Teppema - PLoS medicine, 2007 - journals.plos.org
Background Human breathing is regulated by feedback and feed-forward control
mechanisms, allowing a strict matching between metabolic needs and the uptake of oxygen …

Differential cerebrovascular CO2 reactivity in anterior and posterior cerebral circulations

RJ Skow, CM MacKay, MM Tymko, CK Willie… - Respiratory physiology …, 2013 - Elsevier
The potential differences in cerebrovascular responses between the anterior and posterior
circulations to changes in CO 2 are unclear in humans. Using transcranial Doppler …

The ventilatory responsiveness to CO2 below eupnoea as a determinant of ventilatory stability in sleep

JA Dempsey, CA Smith, T Przybylowski… - The Journal of …, 2004 - Wiley Online Library
Sleep unmasks a highly sensitive hypocapnia‐induced apnoeic threshold, whereby apnoea
is initiated by small transient reductions in arterial CO2 pressure (PaCO2) below eupnoea …

A model of the chemoreflex control of breathing in humans: model parameters measurement

J Duffin, RM Mohan, P Vasiliou, R Stephenson… - Respiration …, 2000 - Elsevier
We reviewed the ventilatory responses obtained from rebreathing experiments on a
population of 22 subjects. Our aim was to derive parameter estimates for an 'average …
