Study Procedures: All selected individuals will be suffering from electrolyte imbalance (EI) with the following data will be obtained:
o Measurements:
- Demographic data: age - gender - BMI - electrolytes data on ICU admission
- Vital data: heart rate - respiratory rate - blood pressure measurement - Oxygen saturation - Urinary output - Temp +/- CVP measurement.
- Lab.: "CBC - Kidney function tests - liver function tests - ABG - levels of serum sodium, potassium, magnesium, phosphorus, ionized calcium and chloride", with maximum 5 mm blood sampling per day. Serum-sodium levels will be corrected for serum-glucose by lowering the sodium concentration by 2.4 mmol/L for every 100 mg/dl increase in glucose. Corrected Sodium = Measured sodium + 0.016 (Serum glucose - 100) A correction formula was also used to calculate albumin-corrected calcium levels (mmol/L) Corrected Calcium = (0.8 (Normal Albumin - Pt's Albumin)) + Serum Ca
