Nexfin Noninvasive Continuous Hemodynamic Monitoring: Validation against Continuous Pulse Contour and Intermittent Transpulmonary Thermodilution Derived Cardiac Output in Critically Ill Patients
Figure 3
Four quadrants trend plot. (a) Plot for 90 paired measurements of NeXCO and TDCO. From the 90 initial paired measurements, 34 pairs were excluded (exclusion zone is indicated as grey dots within grey-shaded square) because either NexCO or TDCO was ≤ ±15% or because NexCO or TDCO was equal to zero. The calculated level of concordance was 89.3% (50/56) (6 pairs felt within the upper left or lower right quadrant and correspond to poor concordance, black dots). See text for explanation. (b) Plot for 180 paired measurements of NeXCO and CCO. From the 180 initial paired measurements, 75 pairs were excluded (exclusion zone is indicated as grey-shaded square) because either NexCO or CCO was ≤ ±15% change or because NexCO or CCO was equal to zero. The calculated level of concordance was 81% (85/105). See text for explanation.
