What is the Penn State Equation?

The Penn State Equation is used to estimate the calorie needs of critically ill patients.

Penn State Equation Calculator

This calculator uses the Penn State Equation to determine the caloric needs of critically ill patients. It is designed for healthcare professionals and nutritionists seeking to optimize nutritional support.

Caloric Needs: 0 kcal/day

Data Source and Methodology

Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da NCBI.

The Formula Explained

The Penn State Equation is used to estimate the resting energy expenditure (REE) of critically ill patients.

\[ REE = 0.85 \times (10 \times weight + 6.25 \times height - 5 \times age + 5) \]

Glossary of Terms

Patient Weight: The current weight of the patient in kilograms.
Height: The height of the patient in centimeters.
Age: The age of the patient in years.
Caloric Needs: The estimated daily caloric needs of the patient.

How It Works: A Step-by-Step Example

Let's assume a patient weighs 70 kg, is 175 cm tall, and is 65 years old. By inserting these values into the equation, we calculate the patient's caloric needs.

Frequently Asked Questions (FAQ)

Why use the Penn State Equation?

It is specifically designed for estimating the caloric needs of critically ill patients.

Can this calculator be used for non-critical patients?

While it is designed for critically ill patients, it may provide insights for other uses with caution.

How accurate is this calculator?

The accuracy depends on the input data and adherence to the formula guidelines.

Is this tool free to use?
