WebJul 16, 2024 · High altitude is characterized by the sustained decrease in atmospheric oxygen, with the decrease in oxygen a function of the degree of elevation ( Bigham and Lee, 2014 ). Given the physiological challenge imposed by high altitude, renal adaptation could become overloaded leading to renal tissue injury. WebMar 22, 2013 · The clinically most prominent physiologic change at high altitude is the hypoxic ventilatory response: hyperpnea and tachypnea leading to hypocapnia [].Hypoxia may trigger several receptors, including airway chemoreceptors [].Tissue hypoxia also induces the production of hypoxia-inducible factor (HIF) transcription factors [34, 35] …
WebJul 12, 2024 · Oxygen Consumption As work increases, oxygen consumption (Vo2) increases proportionally until it plateaus. This plateau occurs at the AT. Oxygen consumption is at a maximum (VO2 max), and oxygen uptake remains at this point because it is not possible to further increase the cardiac output.
