AltitudeOmics : Resetting of Cerebrovascular CO2 Reactivity Following Acclimatization to High Altitude. [PDF]

, 2015
Previous studies reported enhanced cerebrovascular CO2 reactivity upon ascent to high altitude using linear models. However, there is evidence that this response may be sigmoidal in nature.

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

The role of acid‐base balance in cerebrovascular and ventilatory responses to CO2 during 10 h normobaric hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Ventilatory and cerebrovascular responses to exercise in lowlander children acclimatizing to high‐altitude

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate age‐related differences in ventilatory and cerebrovascular responses to exercise at high‐altitude, adults (n = 10, 23–44 years) and children (n = 8, 7–14 years) completed progressive cycling exercise tests at sea‐level and following 6 days of acclimatization at 3800 m.

Elevated carotid body tonic activity contributes to ventilatory acclimatization and de‐acclimatization to high altitude at rest and during exercise

The Journal of Physiology, EarlyView.
Abstract figure legend Participants spent 13 days at high altitude (3800 m), where the reduced inspired oxygen pressure (↓PiO2$ \downarrow {P_{{\mathrm{i}}{{\mathrm{O}}_2}}}$) which elicited ventilatory acclimatization and increased inhibition of ventilation by transient hyperoxia (ΔV̇E$\Delta {\dot V_{\mathrm{E}}}$).

The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia in high‐altitude deer mice (Peromyscus maniculatus)

The Journal of Physiology, EarlyView.
Abstract figure legend The influence of haemoglobin–O2 affinity on aerobic capacity in hypoxia has been contentious. Many high‐altitude natives have greater haemoglobin–O2 affinity (lower P50, the O2 pressure at 50% haemoglobin saturation) than their low‐altitude counterparts, but the advantages of this change for aerobic metabolism have often remained
