## Which of the following is used to estimate energy requirements for a hospital patient?

Abstract Predictive equations

Abstract. Predictive equations are a quick and non-invasive way to estimate a patient’s energy requirements, and can be a useful tool when used appropriately.

## What is the formula for calculating energy expenditure?

The calculators for both sexes are as follows:

- For men: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5.
- For women: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161.

**What is bomb in bomb calorimeter?**

The bomb calorimeter is used to determine the calorific values of solid and liquid fuels. It consists of a strong steel shell known as a bomb. It consists of a base which supports the platinum crucible and is screwed to the body of the bomb.

**How is indirect calorimetry tested?**

An indirect calorimetry test requires two simple 10-minute breathing tests. It measures your daily resting energy expenditure (your calorie needs at rest). This translates into your actual metabolic rate. This translates into your actual metabolic rate.

### How do you use the Harris-Benedict equation?

How do I calculate my BMR? To calculate your BMR, you would usually use the Harris-Benedict equation: For women, it’s: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) – 161 . For men, the formula is: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) + 5 .

### What is the Harris-Benedict BMR formula?

In men, the Harris-Benedict equation formula used was: BMR=66.4730 + 13.7516 x weight in kg + 5.0033 x height in cm – 6.7550 x age in years. In women, BMR=655.0955 + 9.5634 x weight in kg + 1.8496 x height in cm – 4.6756 x age in years.

**What is GCV and NCV?**

The calorific value of a fuel represents the energy released as heat during combustion. The “Effluent Treatment” laboratory is equipped with a calorimeter, which is used to determine gross calorific value (GCV). The hydrogen content of the fuel is then measured in order to calculate net calorific value (NCV).

**How do you calculate bomb calorimeter?**

In this technique, a sample is burned under constant volume in a device called a bomb calorimeter. The amount of heat released in the reaction can be calculated using the equation q = -CΔT, where C is the heat capacity of the calorimeter and ΔT is the temperature change.

## How do you calculate REE from indirect calorimetry?

Weir equation used to calculate energy expenditure: Energy expenditure = (3.9VO2 – 1.1VCO2) – 2.17 (urinary nitrogen) Abbreviated Weir Equation = used to calculate REE: REE = (3.94 x VO2) + (1.1 x VCO2)
