The Transthoracic electrical impedance (TEI) was measured using the Bomed NCCOM3 non-invasive cardiac output monitor in 27 patients with polycythemia rubra vera (PCRV) and in a control group of 27 patients with normal haematocrits. The mean haematocrit was 49.4% (SD 2.61) in the patients with PCRV and 42.1% (SD 2.95) in the control group, a difference that was significant (p less than 0.001). The mean TEI was also significantly higher in patients with PCRV than in the control group (p less than 0.05), the respective values being 31.25 (5.48) Ohms and 27.5 (3.31) Ohms. The mean values for cardiac output (CO) and cardiac index (CI) were similar in both groups.
采用Bomed NCCOM3无创心输出量监测仪对27例真性红细胞增多症（PCRV）患者和27例血细胞比容正常的对照组患者进行经胸电阻抗（TEI）测量。PCRV患者的平均血细胞比容为49.4%（标准差2.61），对照组为42.1%（标准差2.95），差异有统计学意义（p<0.001）。PCRV患者的平均TEI也显著高于对照组（p<0.05），分别为31.25（5.48）欧姆和27.5（3.31）欧姆。两组的心输出量（CO）和心脏指数（CI）平均值相似。
