Fig. 3From: A preliminary study evaluating cardiac output measurement using Pressure Recording Analytical Method (PRAM) in anaesthetized dogsFour-quadrant plot. Sequential percentage changes (∆CO) of PRAM-CO (Y axis) and of TD-CO (x axis). The central grey zone represents the exclusion area that contains ∆CO < 10%. Upper right and lower left quadrant contain concordant ∆CO, upper left and lower right quadrant contain discordant ∆COBack to article page
