GRADUATED COMPRESSION TECHNOLOGY
Graduated compression technology delivers a compressive action to the leg that is greatest at the ankle, decreasing gradually up the leg, towards the heart. The amount of compression is expressed as mmHg (millimeters of mercury) - a measurement of pressure.
PROVIDING TWO PRIMARY BENEFITS TO THE LEGS:
The most beneficial effect is action on the capillaries and tissues. Compression applied in this manner will increase pressure on tissues beneath the skin, which helps to reduce leakage of fluid from the capillaries. This helps to increase the return of fluid to the capillaries and lymph vessels, in turn reducing and preventing swelling.
A secondary benefit is the presence of the stocking on the leg which helps control the size (diameter) of the superficial veins that lie just beneath the skin. The compressive action of the garment prevents the slowing of blood flow and blood "pooling". The blood in the veins can then flow more quickly up the leg back toward the heart.
GRADUATED COMPRESSION TECHNOLOGY SUPPORTS THE VENOUS SYSTEM
Over 60% of our blood volume is carried in the veins which transport blood from the body back to the heart. The veins of the legs are located below and far from the heart, so blood return from the legs occurs primarily through the deep veins.
With veins strategically placed within the leg muscles, return flow of blood is accomplished in gradual stages by the combination of the one-directional "cup-like" valves and the leg muscles. When muscles contract blood within the veins is squeezed up the vein which opens the valves. When the muscle rests, the valves close helping to prevent unhealthy backward flow. This is referred to as the skeletal muscle pump.
Truform graduated compression support hosiery works in concert with the veins, skeletal muscle pump and valves to help maintain good circulation and leg health.
