Pedal Edema

Pedal edema is the swelling of the feet. The causes of pedal edema can be a number of things such as conditions, diet, diseases and injury. Edema results whenever small blood vessels become "leaky" and release fluid into nearby tissues. The extra fluid accumulates, causing the tissue to swell.

It can be categorized into pitting or non-pitting.

     Nonpitting edema - edema in which pressure does not leave a depression in the tissues.

     Pitting edema - edema in which external pressure leaves a persistent depression in the tissues. It occurs because the pressure pushes the excess fluid out of the intercellular spaces in the tissue.


Activity allows the user to check the swelling in the leg and feet of the patient.
