A. Arteriolar oxygen pressure, B. Venular oxygen pressure and C. Arteriolar Hb-O2 saturation and D. Venular Hb-O2 saturation. †, P < 0.05 relative to baseline. Both arteriolar and venular PO2 and Hb-O2 saturation in the microcirculation decreased in the group with systemic decreased Hb-O2 affinity (magnetic field OFF). Intravascular Hb-O2 saturation for the group treated with L35-PMNPs with magnetic field ON were assumed to similar to untreated animals. This assumption over-estimates venular Hb-O2 saturations, as the blood treated locally with L35 should have a decreased Hb-O2 affinity than untreated blood.
