Understanding Compression Stockings: Pressure Values, Graded Compression, mmHg, and Denier
Introduction:
Compression socks are a functional product widely used in the field of healthcare products. However, choosing the right compression socks can be confusing, especially when understanding terms like pressure value, classification, mmHg, and Denier. We will introduce these terms one by one.

Pressure Value
Pressure value refers to the degree of pressure applied by compression socks to specific areas. It is usually expressed in millimeters of mercury (mmHg). A higher pressure value indicates stronger pressure applied by the compression socks. The choice of compression socks should be based on individual needs and foot conditions. Mild compression socks are generally 15-20 mmHg, moderate compression socks are 20-30 mmHg, and strong compression socks are over 30 mmHg.
Classification System
Compression socks are often classified based on their pressure value and function. The most common classification systems include Class I to Class IV. Class I compression socks are typically used for mild venous circulation problems, Class II compression socks are suitable for moderate venous circulation problems, and Class III and Class IV compression socks are used for severe venous circulation problems, such as varicose veins or deep vein thrombosis.
Relationship between mmHg and Denier
mmHg is a unit used to measure the pressure of compression socks, while Denier is used to measure the density and fineness of the compression sock material. A higher Denier value indicates a coarser material, while a lower Denier value indicates a finer material. Generally, a lower Denier value for compression socks means the socks are thinner and softer, making them more suitable for prolonged wear and daily use.
