Evolution of partial pressure of oxygen (pO2) (measured by arterial gasometry) and electric current (nA) (measured by oxygen electrochemical sensors) in ex vivo (a) and in vivo (b) models during the ventilatory hypoxia induction protocol. Data are expressed as mean ± SEM. N = 6 animals, 6 electrochemical sensors tested ex vivo and 6 electrochemical sensors tested in vivo
