Variations in dialyser pressure and UF coefficients. Variation in (a) the pressure at the dialyser inlet and outlet (p < 0.02 for differences between P_in and NP_in) and (b) the UF coefficient of the dialyser (p < 0.02 for differences between P and NP) for Q _b = 100, 150, 250, and 300 according to pump type and the mean blood flow rate. P_in and P_out are the pressures at the dialyser inlet and outlet, respectively, in the pulsatile pump group. NP_in and NP_out are the pressures at the dialyser inlet and outlet in the non-pulsatile pump group. K _uf indicates the UF coefficient of the dialyser, P and NP are the UF coefficients in the pulsatile and non-pulsatile groups, respectively, and Q _b indicates the mean blood flow rate.
