How does one calculate the compression in stocking?
20 to 30 or 30 to 40 mmHg pressure. This should be shown on the box.
Medium grade 20-30 mm. High grade 30-40.
The degree of compression one needs depends on the indication for wearing them. Typically, the more severe the symptoms the greater the compression.
There are recommended levels of compression dependent on the degree of venous disease. The more severe the vein problem. the higher the compression.
The appropriate compression varies for each individual depending on the extent of the condition being treated.Thus , medical studies measuring intra-venous "ambulatory pressure" exist. In an individual without significant varicose veins, and leading an active ambulatory lifestyle may onlt require a 20-30mmHg compression at the ankle. A less active patient with severe "ambulatory hypertension" may require a 40-50mmHg pressure at the ankle.
