16" - 19" (40.5 - 48cm), Leg Length: 18" - 20" (45.5 - 51cm). Designed by leading vascular specialists, Medline's EMS anti-embolism stockings provide a tailored, contoured fit with just the right amount of gradient pressure. Pressure is greatest at the ankle and gradually reduces throughout the length of the leg. Stockings are constructed of 85 percent nylon and 15 percent spandex and are available in knee- and thigh-length to meet specific patient needs. Measuring tapes to assist in determining correct patient sizing are included in each box. Medline has developed a unique color code system for fast, positive product identification and accurate patient fitting. Each package of stockings is identified and color-coded to correspond to one of the colors and sizes at the carton dispenser end. Size and order number are clearly labeled on each stocking.
