In mountaineering, the death zone refers to altitudes above which the pressure of oxygen is insufficient to sustain human life for an extended time span. This point is generally agreed as 8,000 m (26,000 ft), where atmospheric pressure is less than 356 millibars (10.5 inHg; 5.16 psi). [ 1 ]
In the death zone, the human body cannot acclimatize. An extended stay in the death zone without supplementary oxygen will result in deterioration of bodily functions, loss of consciousness, and, ultimately, death. [3] [4] [5] The summit of K2, the second highest mountain on Earth, is in the death zone.
On July 18, 2023, Hugo Ayaviri climbed Gasherbrum II without oxygen, the fourth 8000’er in his quest to be the first Bolivian to summit all fourteen 8000m peaks. [35] On July 19, 2023, Andrzej Bargiel made the highest descent from Gasherbrum II on skis. He summitted the mountain without the use of supplementary oxygen and began his ski ...
In the region from sea level to around 3,000 m (10,000 ft), known as the physiological-efficient zone, oxygen levels are usually high enough for humans to function without supplemental oxygen and altitude decompression sickness is rare. The physiological-deficient zone extends from 3,600 m (12,000 ft) to about 15,000 m (50,000 ft).
In May 2019, Sirbaz became the first Pakistani to successfully summit the 8,516-metre (27,940-foot) high Mount Lhotse – the world’s 4th highest mountain - without using supplementary oxygen. [8] In July 2019, Sirbaz climbed the summit of the 8,047-metre (26,401 ft) Broad Peak mountain in Pakistan, without using supplementary oxygen. [9]
Chimborazo is only the 39 th tallest mountain in the Andes, when measured from sea level, but there was a brief time in the 19 th century when it was thought to be the world’s highest peak.
On 4 June, Edward Norton, without supplemental oxygen, reached a point on the mountain's Great Couloir 8,572.8 m (28,126 ft) high, his companion Howard Somervell having turned around a short distance before. [24] This was an altitude record which would not be broken, with certainty, until the 1950s, or without supplemental oxygen until 1978.
A 2022 Outside article on heat stroke cites the highest known body temperature that a human was able to survive: “The highest body temperature measured was only 17 degrees above normal. Willie ...
