Cerebral oxygenation in highlanders with and without high-altitude pulmonary hypertension.

Furian M1,2, Latshang TD1, Aeschbacher SS1, Ulrich S1, Sooronbaev T3, Mirrakhimov EM3, Aldashev A4, Bloch KE1.
Experimental physiology.Exp Physiol.2015 Aug;100(8):905-14. doi: 10.1113/EP085200. Epub 2015 Jul 5.
NEW FINDINGS: What is the central question of this study Cerebral hypoxia impairs cognitive function and exercise performance and may result in brain damage. Residents at high altitude, in particular those with high-altitude pulmonary hypertension, are prone to hypoxaemia due to the exposure to red

Cerebrovascular reactivity is increased with acclimatization to 3,454 m altitude.

Flück D1, Siebenmann C2, Keiser S1, Cathomen A3, Lundby C4.
Journal of cerebral blood flow and metabolism : official journal of the International Society of Cerebral Blood Flow and Metabolism.J Cereb Blood Flow Metab.2015 Aug;35(8):1323-30. doi: 10.1038/jcbfm.2015.51. Epub 2015 Mar 25.
Controversy exists regarding the effect of high-altitude exposure on cerebrovascular CO2 reactivity (CVR). Confounding factors in previous studies include the use of different experimental approaches, ascent profiles, duration and severity of exposure and plausibly environmental factors associated w

179 Brain Tissue Oxygen Tension and Its Response to Physiological Manipulations Is Dependent on Distance From Injury Site in a Swine Model of Traumatic Brain Injury.

Hawryluk GW, Phan N, Ferguson A, Morabito D, Derugin N, Stewart C, Knudson M, Manley GT, Rosenthal G.
Neurosurgery.Neurosurgery.2015 Aug;62 Suppl 1:225. doi: 10.1227/01.neu.0000467143.66138.47.
INTRODUCTION: The optimal site for placement of tissue oxygen probes following traumatic brain injury (TBI) remains unresolved. We studied brain tissue oxygen tension (PbtO2) at the sites of contusion, proximal and distal to contusion, and in the contralateral hemisphere to determine the effect of p
