采用常规快速流动法研究了血红蛋白的氧合速度。具体来说，在四个和多个射流型混合室中进行了比较。结果，在反应初期，后一个多重喷射室中SO2的上升幅度更大，这可能是由于混合效率的提高。在本研究中，氧合速度用速率因子表示，该速率因子是通过将氧气吸收量除以周围介质的背压和PO2之间的差来计算的。前一压力是参照SO2从Hb的O2解离曲线中读出的。该因子与欠饱和程度不是线性成正比，而是上升到欠饱和程度的1.6次幂。
The oxygenation velocity of Hb was studied by using the conventional rapid flow method. Specifically, it was compared in four and multiple jet type mixing chambers. As a result a steeper rise of SO2 was observed in the latter multiple jet chamber at an early stage of reaction, probably due to the enhanced efficiency of mixing.The oxygenation velocity was expressed in this study by a rate factor which was calculated by dividing the O2 uptake by the difference between the back pressure and the PO2 of the surrounding medium. The former pressure was read from the O2 dissociation curve of Hb by referring to the SO2. This factor was not lineally proportional to the undersaturation, but went up to the 1.6th power of it.
