Experiments were performed to determine whether the skin blood flow could be measured using inhaled hydrogen gas clearance method. The mean finger blood flow of the normal subjects obtained by this method was about 53.6±9.7ml/100g/min. The values obtained in the first measurement were correlated with those in the second measurement on the subjects (r=0.950. p<0.001). When the pneumatic tourniquet was inflated to 140mmHg and then deflated to 0 mmHg, the half period of the clearance curve has changed with the pressure of the pneumatic tourniquet. And then, about eighty-two per cent of the hydrogen clearance curves were monoexponential curve. In the biexponential curve, the value of blood flow obtained from total flow method was more akin to that in the monoexponential curve than that from initial slope method. Therefore, this method can be clinically applied to measure the blood flow of skin and finger for the diagnosis of the peripheral circulatory disorder.
