Figure 5From: A practical guide to bioelectrical impedance analysis using the example of chronic obstructive pulmonary disease Oedema due to right heart failure as illustrated in the BIVA nomogram. The position of the measurement point in the BIVA nomogram is above the line of normal BCM values (long axis) and well below the line of normal TBW values (short axis) on the 95th tolerance ellipse. The position in the lower left quadrant indicates the presence of increased water retention.Back to article page
