Figure 5From: Virtual cooperativity in myoglobin oxygen saturation curve in skeletal muscle in vivoCorrelation between O2 consumption at 50% of Mb oxygenation (VY50) and calculated O2 gradient from vascular to cytoplasmic space in perfused hindlimb muscle (ΔPO2). To calculate ΔPO2, PO2 = 2.3 mmHg at Y = 50% of Mb in the perfused muscle was used [21]. ΔPO2 = -1635* VY50 + 1269 (r2 = 0.9995).Back to article page
