How to Calculate Feeding Tube Rates
Calculating the correct feeding tube rate is critical for ensuring patients receive adequate nutrition and hydration. The process involves converting a daily caloric requirement into a practical hourly flow rate for a feeding pump.
The Core Formula
To find the rate, we use two primary calculations:
- Total Volume (mL) = Total Daily Calories (kcal) / Formula Density (kcal/mL)
- Flow Rate (mL/hr) = Total Volume (mL) / Infusion Duration (Hours)
Example Calculation
If a patient requires 1,800 kcal per day using a formula with 1.2 kcal/mL density over a 24-hour period:
- Total Volume: 1,800 / 1.2 = 1,500 mL
- Flow Rate: 1,500 / 24 = 62.5 mL/hr
Common Formula Densities
| Density Type | kcal/mL | Common Use Case |
|---|---|---|
| Standard | 1.0 | Normal fluid/caloric needs |
| Moderate Concentration | 1.2 | Increased caloric demand |
| High Calorie | 1.5 | Fluid restriction or high needs |
| Concentrated | 2.0 | Severe fluid restriction |
Important Considerations
Hydration: Enteral formulas contain water (typically 70-85%), but most patients require additional water flushes to meet total hydration goals. This calculator includes a flush field to help estimate total fluid intake.
Tolerance: Always start feeding rates according to clinical protocols, often beginning at a lower rate (e.g., 10-40 mL/hr) and advancing as tolerated by the patient.
