Impaired peripheral oxygenation (IPO) of exercising muscles is caused by impaired circulation and/or mitochondrial function and a low arterial oxygen content, such that oxygen cannot flow adequately to myocytes. 1 The mechanisms of IPO are quite different from those of hypoxemia, mostly due to respiratory pathology. IPO can seriously …
