📋 Quick Reference Guide

• ✓ TPN (Central Line): High osmolarity >900 mOsm/L, suitable for central venous access
• ✓ PPN (Peripheral Line): Lower osmolarity <900 mOsm/L, for peripheral veins
• ✓ GIR (Glucose Infusion Rate): 4-6 mg/kg/min typical, max 5-8 depending on tolerance
• ✓ Osmolarity Formula: (Dextrose g × 5) + (Amino Acid g × 10) + (Lipid g × 1.5) ÷ Volume (L)

📊 How to Use This Calculator

⚖️ Step 1: Enter Weight

Input patient weight in kg. GIR automatically adjusts based on dextrose grams.

📝 Step 2: Adjust Macronutrients

Modify dextrose, amino acids, or lipid grams. All values update in real-time.

📈 Step 3: Monitor Key Parameters

Check osmolarity, final concentrations, and GIR to ensure safe administration.

⚠️ Clinical Pearl: For PPN, maintain osmolarity <900 mOsm/L to prevent phlebitis. TPN can safely exceed 900 mOsm/L but requires central line placement.

🔬 Understanding the Calculations

Parameter	Formula	Normal Range
GIR	(Dextrose g × 1000) ÷ (Weight kg × 1440)	4-8 mg/kg/min
Dextrose Concentration	(Dextrose g ÷ Total Volume mL) × 100	TPN: 10-35%, PPN: 5-10%
Osmolarity	[5×Dex + 10×AA + 1.5×Lip] ÷ Vol(L)	PPN <900, TPN >900 mOsm/L
