5.0 mmol/L, but every case of Hyperkalemia doesn't require treatment.The management strategy of Hyperkalemia depends upon:Plasma K+ concentrationAssociated muscular weaknessChanges on ECGTreatment of Hyperkalemia is required in following cases:Serum K+ >5 along with ECG manifestation of HyperkalemiaSerum K+ >6 (even when ECG manifestation are not present)In Hyperkalemia the treatment is directed atMinimizing membrane depolarizationRedistribution of potassium (shifting of K+ back into cells)Increased excretion of potassium* Administration of calcium in the form of calcium gluconate, decreases membrane excitabilityQ* Calcium directly reverses the effect of potassium on the cardiac conduction systemQ* Administering insulin and glucose* Alkali therapy with I.V. NaHCO3Q* Beta2 adrenergic agonistQ* (When administered parenterally or in nebulized form, beta2 adrenergic agonist promote cellular uptake of K+)Q* Cation exchange resinQ (Sodium polystyrene sulfonate)* Diuretics (Enhance K+ excretion)Q* Hemodialysis (Most effective and rapid way of lowering plasma K+ conc.)Q">
