J Appl Physiol (1985) 2021 Mar 11. Epub 2021 Mar 11.

Department of Biology, Faculty of Science and Technology, Mount Royal University, Canada.

Rapid ascent to high altitude imposes an acute hypoxic and acid-base challenge, with ventilatory and renal acclimatization countering these perturbations. Specifically, ventilatory acclimatization improves oxygenation, but with concomitant hypocapnia and respiratory alkalosis. A compensatory, renally-mediated relative metabolic acidosis follows via bicarbonate elimination, normalizing arterial pH(a). Read More
