Plasma and erythrocyte K+ were monitored during storage and tonometry of blood samples taken from resting rainbow trout, Oncorhynchus mykiss. During storage of arterial blood samples, plasma K+ concentration increased by 38% in 12 min. During extended tonometry of blood with a pH near 7.9 and full hemoglobin-bound oxygen (HbO2) saturation the erythrocytes showed a net loss of K+. Plasma K+ concentration increased from 2.9 mM to a near steady-state value of 5.6 mM. When tonometered at a pH near… CONTINUE READING
