AbstractA novel method of comparing two impedance cardiographs based on modelling the cardiovascular response to head up tilting is described. A regimen of four sequential 3-minute tilts was used in eight subjects. Continuous stroke volume (SV) and cardiac output (CO) measurements were recorded from: (i) the BoMed NCCOM3 and (ii) the RheoCardioMonitor (RCM). A simulated model of the tilting response was then constructed and fitted to measured data from both devices. The precision ((expected-observed)/expected), as a percentage, was calculated at 10-second intervals and the impedance devices compared using multiple analysis of variance and cumulative sums (cusum) analysis. Baseline values of SV and CO were higher using the BoMed (P<0.01). Mean (s.d) SV precision was marginally better using the RCM 6.5(4.9)% compared to the BoMed 6.8(5.2)% (P=0.048). Cusum plots analysis showed that BoMed readings diverged from the simulation more than RCM readings (P=0.03).
