Fig. 1. Giraffe jugular venous pressures (JVP) as measured by Hargens et al. (Hargens et al., 1987) (circles and solid line) and a linear regression line calculated from the data (broken line). The relationship between height in meters and JVP in mmHg is JVP=0.093xheight–0.022 (r=0.987). The linear regression predicts that right atrial pressure will be 0 mmHg, which is the measured value.
