1 Non-invasive continuous arterial pressure and cardiac index monitoring with Nexfin after cardiac surgery  M.O. Fischer, R. Avram, I. Cârjaliu, M. Massetti, J.L. Gérard, J.L. Hanouz, J.L. Fellahi  British Journal of Anaesthesia  Volume 109, Issue 4, Pages (October 2012) DOI: /bja/aes215 Copyright © 2012 The Author(s) Terms and Conditions

2 Fig 1 The relationship between absolute values of (a) arterial invasive and photoplethysmographic systolic arterial pressure (220 paired data points); (b) arterial invasive and photoplethysmographic diastolic arterial pressure (220 paired data points); (c) arterial invasive and photoplethysmographic mean arterial pressure (220 paired data points); and (d) transpulmonary thermodilution and photoplethysmographic CI (120 paired data points). AI, arterial invasive; CI, cardiac index; DAP, diastolic arterial pressure; MAP, mean arterial pressure; NF, Nexfin; SAP, systolic arterial pressure; TD, transpulmonary thermodilution.

3 Fig 2 Bland–Altman analysis between (a) arterial invasive and photoplethysmographic systolic arterial pressure (220 paired data points); (b) arterial invasive and photoplethysmographic diastolic arterial pressure (220 paired data points); (c) arterial invasive and photoplethysmographic mean arterial pressure (220 paired data points); and (d) transpulmonary thermodilution and photoplethysmographic CI (120 paired data points). Symbols and colours refer to each patient (five observations per individual). AI, arterial invasive; CI, cardiac index; DAP, diastolic arterial pressure; MAP, mean arterial pressure; NF, Nexfin; SAP, systolic arterial pressure; TD, transpulmonary thermodilution.

4 Fig 3 A polar plot comparing changes in CI among data points T0, T1, T2, T3, and T4 (n=96) by bolus transpulmonary thermodilution and digital photoplethysmography (Nexfin) CI. The distance from the centre of the plot represents the mean change in CI and the angle with the horizontal (0° radial) axis represents agreement. 99% of CI changes were within 0.4 litre min−1 m−2 limits of agreement (20%).
