Effect of hypoxia on arterial potassium concentration at rest and during exercise in man.

Abstract:

Hypoxia has been reported to increase arterial potassium concentration ([K+]a) in anaesthetized cats (Paterson, Estavillo and Nye, 1988). The purpose of this study was to determine whether this phenomenon occurs in humans. The effect of hypoxia on [K+]a was measured in ten male subjects, at rest and during light exercise, before and after 8 weeks of physical training. The [K+]a increased by 0.15 +/- 0.04 mM (mean +/- S.E.M.) at rest, when end-tidal PO2 (PET,O2) was lowered from 100 to 51 +/- ...
