Note:—MABP indicates mean arterial blood pressure; PMMA indicates polymethylmethacrylate; HA, hydroxyapatite; MCVP, mean central venous pressure; MPAP, mean pulmonary arterial pressure; CO, cardiac output; CI, cardiac index; HR, heart rate. The values are given as mean ± SD and on the next line as 95% confidence intervals. Unless otherwise indicated, N = 6.
