Continuous renal replacement therapy circuit. Pick a mode, set the blood and effluent flows, and read the live circuit pressures, TMP and ΔP on the console. Load scenarios such as filter clotting, poor access drainage and a kinked return line, and watch the pressure pods and bar gauges respond. Split replacement fluid pre- and post-filter to trade filter life against delivered clearance, or switch on regional citrate anticoagulation with its post-filter calcium infusion.
