The pump applies graded pressure either in a sequential or uniform pattern, which helps promote both lymphatic and venous return. This external compression creates several physiological effects. Firstly, it exerts mechanical pressure that reduces the diameter of lymphatic vessels, pushing the lymph fluid toward larger, more central lymph nodes. Secondly, the gentle compression stimulates the lymphangions, which are the contractile units of the lymph vessels, enhancing their natural pumping activity. This process also helps in the prevention of lymphatic stasis, ensuring that protein-rich lymph fluid does not pool and lead to fibrosis or tissue hardening. Additionally, the compression supports venous return by reducing the diameter of veins and improving blood flow, which in turn helps to decrease venous edema and related discomfort.
