The critical care nurse is responsible for monitoring the patient receiving CRRT. The hemofilter is assessed every 2 to 4 hours for clotting (as evidenced by dark fibers or a rapid decrease in the amount of ultrafiltration without a change in the patient's hemodynamic status). The CRRT system is frequently assessed to ensure filter and lines are visible at all times, kinks are avoided, and the blood tubing is warm to the touch. The ultrafiltrate is assessed for blood (pink-tinged to frank blood), which is indicative of membrane rupture. Sterile technique is performed during vascular access dressing changes.
