The method described is apt to measure, at the same time, Krogh's diffusion constant and specific metabolic rates for O2 and CO2 in intact, respiring tissues. Due to metabolism tissue thickness for this method is limited to about 500 mum unless hyperbaric conditions are used. The results suggest that both KO2 and KCO2 are similar in alive and in dead tissue. Due to tissue inhomogeneity and to possible facilitation of O2 or CO2 transport our values of K have to be considered as effective mean values for the physiological range of PO2 and PCO2 in muscle at rest and at exercise.
所描述的方法易于同时测量完整呼吸组织中克罗格扩散常数以及氧气和二氧化碳的比代谢率。由于新陈代谢，除非采用高压条件，该方法的组织厚度限制在约500微米。结果表明，活组织和死组织中的氧扩散常数（KO2）和二氧化碳扩散常数（KCO2）相似。由于组织的不均匀性以及氧气或二氧化碳运输可能存在的促进作用，我们的K值必须被视为肌肉在静息和运动时PO2和PCO2生理范围内的有效平均值。
