A. Oxygen delivery, B. Oxygen extraction, and C. Oxygen extraction ratio for baseline and after treatment. The O2 delivery for the group with the magnetic field was OFF was significantly lower than the other groups, due to low O2 arteriolar saturation and reduced arteriolar blood flow in the microcirculation. The systemically decreased Hb-O2 affinity in the microcirculation increased O2 extraction ration to preserve O2 extraction (consumption).
