Most are unaware that giraffes have venous pressures of more than 250 mmHg at their ankles? That is three times more than humans. However, giraffes do not suffer from lymphedema or venous disorders.Physiologists have discovered the answer in the skin. Giraffe skin is inelastic, meaning that it does not stretch. Thus, giraffes are not susceptible to problems like lymphedema and venous disease, even though they may be on their feet 24 hours a day.CircAid has incorporated this concept into its products, creating solutions that help patients heal while allowing them to maintain an independent lifestyle.
