Abstract PURPOSE: We compared blood pressure (BP) measurements obtained using radial artery applanation tonometry with invasive BP measurements using a catheter placed in the abdominal aorta through the femoral artery in patients with multiple organ dysfunction syndrome (MODS). MATERIALS AND METHODS: In 23 intensive care unit patients with MODS, we simultaneously assessed BP values for 15 minutes per patient using radial artery applanation tonometry (T-Line TL-200 pro device; Tensys Medical Inc, San Diego, Calif) and the arterial catheter (standard-criterion technique). A total of 2879 averaged 10-beat epochs were compared using Bland-Altman plots. RESULTS: The mean difference ± SD (with corresponding 95% limits of agreement) between radial artery applanation tonometry-derived BP and invasively assessed BP was +1.0 ± 5.5 mm Hg (-9.9 to +11.8 mm Hg) for mean arterial pressure, -3.3 ± 11.2 mm Hg (-25.3 to +18.6 mm Hg) for systolic arterial pressure, and +4.9 ± 7.0 mm Hg (-8.8 to +18.6 mm Hg) for diastolic arterial pressure, respectively. CONCLUSIONS: In intensive care unit patients with MODS, mean arterial pressure and diastolic arterial pressure can be determined accurately and precisely using radial artery applanation tonometry compared with central aortic values obtained using a catheter placed in the abdominal aorta through the femoral artery. Although systolic arterial pressure could also be derived accurately, wider 95% limits of agreement suggest lower precision for determination of systolic arterial pressure.
