Levels that are greater than 2.2 meq/l (or greater than 1.1 mmol/l) are diagnostic for hypermagnesemia. when suspicion for magnesium toxicity is high, workup including an initial ecg as this can be readily done and can identify lethal dysrhythmias that may require emergent treatments. including magnesium and phosphorus, to rule out. Parenteral potassium phosphate contains 93 mg (3 mmol) phosphorus and 170 mg (4.4 meq or 4.4 mmol) potassium per ml. the usual dose is 0.5 mmol phosphorus/kg (0.17 ml/kg) iv over 6 hours. patients with alcohol use disorder may require ≥ 1 g/day during total parenteral nutrition; supplemental phosphate is stopped when oral intake is resumed..
Mmol/l, µmol/l, mg/dl, mg/100ml, mg%, mg/l, µg/ml, meq/l calcium is the most abundant mineral element in the body with about 99 percent in the bones primarily as hydroxyapatite. the remaining calcium is distributed between the various tissues and the extracellular fluids where it performs a vital role for many life sustaining processes..

Sample osmolarity calculations. in some cases the calculated osmolarity of a commercially available preparation is greater or less than what is printed on the vial. in those cases, the manufacturer’s data is used in the osmolarity determination program. calcium chloride:exists as dihydrate (cacl2.2h20). total mw= (40.1 + 35.5 + 35.5+ (2×2) + (2×16)= 146.1 — calculations: (1gram cacl2/146.1) x.
Phosphorus (phosphate) is important in bone formation, energy storage and release, urinary acid-base buffering, and carbohydrate metabolism. >2 mmol/l >2 meq/l: magnesium sulfate: anticonvulsants: 1.7—3 mmol/l: 4—7 mg/dl >3 mmol/l >7 mg/dl: methotrexate (trexall) antimetabolites >0.01 µmol >0.01 µmol >10 µmol/24 hours.
