Non-invasive continuous arterial pressure measurement based on radial artery tonometry in the intensive care unit: a method comparison study using the T-Line TL- 200pro device B Saugel, A.S. Meidert, A Hapfelmeier, F Eyer, R.M.

Fig 1 Comparison of arterial pressure (AP) measurements using a femoral arterial catheter and the TL-200pro device. Bland–Altman plot for MAP (a), SAP (b), and DAP (c) assessed using the TL-200pro device and the femoral arterial catheter. The plots show the bias (black continuous horizontal line) and 95% limits of agreement (bias ±1.96 * sd; black dashed horizontal lines in bold) between TL-200pro-derived AP values and invasively assessed values. The non-uniform relation between differences and mean values of AP variables calculated using mixed models is illustrated by the grey continuous line (with dashed grey lines indicating the corresponding 95% confidence interval).
