These cheerful vinyl stickers were designed by MEI to make it easy to educate patients and staff about keeping Ultrafiltration Rate (UFR) in the green-- a heart-safe zone that avoids organ-stunning. Put this waterproof, reusable, removable UFR Sticker on (or near) the dialysis machine and point your phone at the green heart to scan the QR-code. Then, use our free UFR calculator to take the guess-work out of UFR safety. Great for HHD patients and clinicians!
