Calculates maintenance fluid requirements by weight. Favorite. INSTRUCTIONS. While originally derived in pediatric patients, this calculator is applicable to any age. Consider using ideal body weight in obese patients. If not calculating based on ideal body weight, use clinical judgment for dosing. A 1-liter bolus may be appropriate for most. Under normal circumstances, the kidneys can adjust to wide variations in dietary intake by appropriate variations in water and electrolyte excretion, which is particularly important when discussing maintenance fluid requirements.
Normal daily fluid and electrolyte requirements: 25–30 ml/kg/d water 1 mmol/kg/day sodium, potassium*, chloride 50–100 g/day glucose (e.g. glucose 5% contains 5 g/100ml). Reassess and monitor the patient Stop IV fluids when no longer needed. For most people, attaining these new goals for fluid intake will require a substantial change in daily routine. However, keep in mind that you don't have to take it all in as water (or other beverages). Roughly 80% of your total daily fluid intake comes from drinks; the .
If the serum K level is normal, about 4.5 mEq/L, the total extracellular pool of K + = 4.5 × 14 L = 63 mEq. K is easily interchanged between intracellular and extracellular stores under conditions such as acidemia or . Note: Infusion rate = total fluid volume per day ÷ 24 hour.
