  • a CO, cardiac output; Qa, access flow; SBP, systolic BP; TPR, total peripheral resistance; 1, timing of measuring the parameter is within the first hour after initiation of HD session or immediately before FIR treatment; 2, timing of measuring the parameter is 40 min after timing 1 or immediately after FIR treatment. Boldface P values indicate P < 0.05.
