## 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:

1. For men: BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5.
2. 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)
