For comparison of BP measurements, Bland-Altman analysis accounting for repeated measurements was performed (primary endpoint).RESULTS: A total of 76,826 pairs of BP measurements (each consisting of SAP, MAP, and DAP) were analyzed. For MAP, Bland-Altman analysis revealed a mean difference of +0.47 mmHg (95 % limits of agreement -16.53 to +17.46 mmHg). For SAP and DAP, the bias and 95 % limits of agreement were -9.01 mmHg (-37.47 to +19.45 mmHg) and +5.22 mmHg (-13.50 to +23.94 mmHg), respectively.CONCLUSIONS: Non-invasive, continuous, radial BP measurement with the T-Line TL-200 is basically feasible in medical ICU patients (with a low bias for MAP compared to MAP assessed using a femoral arterial catheter). High limits of agreement (particularly of SAP and DAP) preclude the use of the device as a single source of BP information in unstable critically ill patients.",
