Effect of gravitational preload change on jugular and hepatic veins. A 2 × 2 diagnostic accuracy matrix for jugular morphology versus preload, FN is false negative, TN is true negative, TP is true positive and FP is false positive B agreement between the jugular vein and hepatic vein morphologies at different preload conditions. C Examples of jugular and hepatic vein Doppler at low (left most) versus high (right most) preload conditions
