Cerebral artery dilatation maintains cerebral oxygenation at extreme altitude and in acute hypoxia : an ultrasound and MRI study [PDF]

, 2011
Transcranial Doppler is a widely used noninvasive technique for assessing cerebral artery blood flow. All previous high altitude studies assessing cerebral blood flow (CBF) in the field that have used Doppler to measure arterial blood velocity have ...

Prevention and treatment of high altitude cerebral edema (HACE)

Journal of Education, Health and Sport, 2020
High altitude cerebral edema (HACE) is often a severe and potentially fatal manifestation of acute mountain sickness (AMS). It usually develops within the first 2 in individuals rapidly ascending at altitudes above 4000 m.

Mean corpuscular haemoglobin concentration (MCHC): a new biomarker for high-altitude pulmonary edema in the Ecuadorian Andes

Scientific Reports, 2022
Ascent to high altitude (> 3000 m height above sea level or m.a.s.l) exposes people to hypobaric atmospheric pressure and hypoxemia, which provokes mountain sickness and whose symptoms vary from the mild acute mountain sickness to the life-threatening ...

Comparison of Simulated High Altitude Pilot Effective Performance Time Between Habitual Smokers and Non-Smokers

, 2003
Smoking attenuates the amount of oxygen that diffuses from the lung tissue and oxygenates the blood (Guyton, 1996). High altitudes attenuate the oxygen available for transport to the blood.

Examination of novel diagnostic approaches and contemporary strategies for preventing acute mountain sickness

Journal of Education, Health and Sport
Introduction and purpose: Acute mountain sickness is caused by hypoxia, of which the brain is the most sensitive. The frequency of occurrence at altitudes above 2500 m above sea level may reach up to 75% of travelers.
