Table 1 Values of muscle perfusion parameters and Mb oxygenation parameters in various tissue respiration states

From: Virtual cooperativity in myoglobin oxygen saturation curve in skeletal muscle in vivo

Respiration state: Suppressed (0.4 mM KCN) Control Enhanced (5 μM DNPa) Enhanced (10 μM DNP)
Influent PO2 700 700 700 700
Effluent PO2 652 ± 14 579 ± 6 512 ± 15 418 ± 18
   Vmaxb 0.09 0.27 0.42 0.68
   PV50c 83 160 170 180
  1. a, 2,4-dinitorophenol; b, Maximal value of steady-state O2 uptake rate (V) at infinite influent PO2 (in μmol/min/g muscle); c, effluent PO2 at V = half Vmax (in mmHg). Values of Vmax and PV50 were obtained from solid lines shown in Figure 2.
