Expedition 5300: limits of human adaptations in the highest city in the world

open access: yesThe Journal of Physiology, Volume 602, Issue 21, Page 5449-5462, 1 November 2024.
Abstract figure legend La Rinconada is the highest city in the world, spread over the mountain above the Peruvian Altiplano from 5000 to 5300 m. At this altitude, the inspiratory oxygen partial pressure is only 50% of the sea level value. The most striking physiological effect of chronic severe hypoxia in dwellers from La Rinconada is the large ...

A narrative review of periodic breathing during sleep at high altitude: From acclimatizing lowlanders to adapted highlanders

open access: yesThe Journal of Physiology, Volume 602, Issue 21, Page 5435-5448, 1 November 2024.
Abstract figure legend Upon ascent to high altitude in lowlanders, periodic breathing during sleep is almost universal among sojourners. With acclimatization in lowlanders (i.e. day to weeks at high altitude), periodic breathing persists and there appears to be a lengthening of cycle length.
