Compression garments are generally classified according to the pressure in mmHg (millimeters of mercury) that they exert on the wearer's body.
In this sense, we can find garments with the following pressure levels:
Gentle compression: these are garments with a pressure between 8 and 15 mmHg, used for the prevention of circulatory disorders, reticular varicose veins and the treatment of tired legs.
Medium or therapeutic compression : The pressure ranges from 20 to 40 mmHg and is beneficial for slightly swollen legs, small varicose veins or leg discomfort during pregnancy.
Medical compression: These garments have a pressure of 20 to 40 mmHg, in some cases up to 50 mmHg, and are used when you want to improve blood circulation during prolonged standing or sitting, for the treatment of muscle and joint pain and during sports.
High Compression: these garments create a pressure of 40-60 mmHg and are used to treat conditions such as primary lymphedema, post-decongestive therapy or severe post-thrombotic syndrome.
