🧴 Maintenance Fluids (4-2-1)

Holliday-Segar method for hourly maintenance fluid rate by weight.

Maintenance rate

⚖️ Body Mass Index (BMI)

Calculate BMI and classify the result automatically.

Body Mass Index

🫘 Creatinine Clearance (GFR)

Cockcroft-Gault estimate of renal function for dose adjustment.

Creatinine Clearance

Corrects serum sodium for hyperglycemia (per 100 mg/dL above 100).

Corrected Sodium
mEq/L

🦴 Corrected Calcium

Adjusts calcium for albumin level — key in renal and liver disease.
