The human body can adapt to high altitude through both immediate and long-term acclimatization. At high altitude, in the short term, the lack of oxygen is sensed by the carotid bodies, which causes an increase in the breathing depth and rate (hyperpnea). However, hyperpnea also causes the adverse effect of respiratory alkalosis, inhibiting the respiratory center from enhancing the respiratory rate as much as would be required. Inability to increase the breat… WebA literature search on high-altitude medicine and physiology was performed in June 2024 in PubMed of the National Library of Medicine of the United States, using “hemoglobin,” “hematocrit,” “oxygen transport,” and “high altitude” or “highlanders” as keywords.
