Figure 3. Quantification of lymphatic contraction.

Figure 3

Vessel diameters are measured over time and from these measurements we calculate contraction amplitude, contraction frequency, ejection fraction and lymph output. The ejection fraction is a measure of the fraction of fluid that is driven out of the vessel with each contraction. This gives a measure of the strength of lymphatic contraction. The lymph output is a measure of the amount of lymph pumped per time normalized to a unit length of vessel.
