Use of PIKRT in the ICU. PIKRT can be used as a substitute for CKRT or intermittent HD, or as a transition between CKRT and intermittent HD during de-escalation of care in the ICU. The Cardiovascular Sequential Organ Failure Assessment (CV-SOFA) score is one of the many tools used to determine hemodynamic stability of the patient. CV-intermittent HD SOFA SCORE: mean arterial pressure (MAP) >70=0, MAP <70 mm Hg =1, dopamine ≤5 or dobutamine (any dose) =2, dopamine >5, epinephrine ≤0.1, or norepinephrine ≤0.1=3, dopamine >15, epinephrine >0.1, or norepinephrine >0.1=4.
