Calcium chloride (10–20 mg/kg IV) directly antagonizes the effects of potassium on the cardiac cell membranes. Sodium bicarbonate in dose of 1 to 2 mEq/kg or a dose calculated from acid–base measurements
Activity of the Na+,K+-2Cl− transporter requires the presence of a parallel potassium conductance in the urinary membrane. This luminal secretory potassium channel is encoded by the ROMK (rat outer medullary K+ channel) gene.61,62 Loss-of-function mutations in ROMK lead to antenatal Bartte...

Plasma potassium is normally kept at 3.5 to 5.5 millimoles (mmol) [or milliequivalents (mEq)] per liter by multiple mechanisms.[62] Levels outside this range are associated with an increasing rate of death from multiple causes,[63] and some cardiac, kidney,[64] and lung diseases progress ...
10. K Restriction Target Value 10.1. Target Value for Patients with Conservative Renal Failure For CKD patients, it is recommended that the serum K level should be regulated in the range of 4.0–5.4 mEq/L. However, since renal K excretion decreases as renal function declines, target values fo...
