High altitude and oxygen level
Web1 de fev. de 2006 · Abstract. Research on humans at high-altitudes contributes to understanding the processes of human adaptation to the environment and evolution. The unique stress at high altitude is hypobaric hypoxia caused by the fall in barometric pressure with increasing altitude and the consequently fewer oxygen molecules in a breath of air, … Web19 de jan. de 2024 · At high altitudes, considered those higher than 2500 m (~8200 ft) above sea level, physiologic responses may start to represent challenges for the human body. This article reviews available evidence on the effects of high altitude among patients with cardiovascular conditions, and the risks of developing clinical cardiovascular events.
