Many of you have asked what is mmHg or mm Hg (it is written both ways) when we talk about compression hose. “mmHg” stands for millimeters of Mercury. This measurement is the same measurement used to measure your blood pressure as well as the atmospheric pressure. It is the force per unit area exerted by an atmospheric column (that is, the entire body of air above the specified area). When you have a blood pressure reading, such as “120/80 mmHg,” we say it is “120 over 80 millimeters of mercury.” The top number, the systolic reading, measures arterial pressure during the heart’s contraction. The bottom diastolic number assesses arterial pressure when the heart is relaxing between beats, refilling itself with blood. When we talk about compression in garments, is usually expressed as a range, i.e. 20-30 mmHg. That is the range of pressure the garment is capable of exerting at the ankle dependent upon the measurements the fitter takes. Since the compression garments are gradient or graduated, the pressure gets less as it goes up the leg and less as it goes toward the toe.
Compression garments were developed when a person with lower extremity venous insufficiency (a condition that occurs when the veins in the legs are not working effectively to pump blood from the legs back to the heart) realized that when they went into a body of water such as a swimming pool the increased pressure in the pool relieved the pain and discomfort from the venous condition. The deeper they progressed in the pool, the more relief they felt. From this discovery a very rudimentary wrap developed which reduced the swelling or edema and improved their quality of life.
Through the years, this rudimentary wrap has evolved into the wonderful compression garments we have today. They are available in many different compressions to accommodate the severity of disease.
Support hose or support socks fit every lifestyle…from the sheerest, most fashionable stockingsm, or men’s dress socks to many types of athletic socks for both men and women. The stockings and socks are made of a wide variety of yarns which include nylon, wool, cotton, polyester, acrylic, and Lycra Spandex or Elasthan (Lacra Spandex or Elasthan is the yarn which give the garment its “stretchability”). All are knit in a manner to move the perspiration next to the skin to the outside of the garment so it can evaporate to keep you more comfortable. Many of our clients have several different styles of stockings and socks to fit their myriad lifestyles.
The stockings you wear with compression (mmHg) are not the old “supp hose” your grandmother use to wear. Call one of our Certified Fitters at 1-800-515-4271 for assistance with the selection of new garments or go to www.supporthosestore.com
