# Children’s Weight Estimation in Intensive Care Units

## According to the study narrative and Figure 1 in the Flannigan et al. (2014) study, does the APLS UK formulae under- or overestimate the weight of children younger than 1 year of age?

According to the narrative and Figure 1 in the Flannigan et al. (2014) study, the APLS UK overestimates the children’s weight on the value from 10 to 25. 4%. Authors used an improved formula, with α=0. 05 which requires the calculation of the age in months and adding 4 inches.

**Using the values ****a ****= 3. 161 and ****b ****= 0. 502 with the novel formula in Figure 1, what is the predicted weight in kilograms (kg) for a child at 9 months of age? **

**a**

**b**

To predict the child’s weight, the following should calculate:

y = 0. 502 * 9 + 3. 161 = 7. 679.

Therefore, the predictable weight of 9 months old child is 7. 679 kg.

## Using the particular values a sama dengan 3. 161 plus b = zero. 502 using the new formula in Physique 1, very best expected weight in kilos for a kid at 2 weeks of age?

To predict the particular child’s weight, the particular following should determine:

y sama dengan 0. 502 2. 2 + a few. 161 = four. 165.

Therefore, the predictable excess weight of 9 weeks old child will be 4. 165 kilogram.

## In Physique 2, the method for calculating con (weight in kg) is Weight within kg = (0. 176 × age group in months) & 7. 241. Exactly what is the con intercept and the particular slope with this method?

Y intercept is the weight in kilos. It is seven. 241.

Y slope is zero. 176 x age group of children within months.

## Using the values the = 7. 241 and b sama dengan 0. 176 along with the novel method in Figure two, what is the particular predicted weight within kilograms for a kid 3 years of age?

First, it is important to calculate the age of a child in months:

3 years = 3*12 = 36 months

y = 0. 176*36+7. 241 = 13. 577

Therefore, the predictable age of 3 years old child is 13. 577 kg.

## Using the values a = 7. 241 and b = 0. 176 with the novel formula in Figure 2, what is the predicted weight in kilograms for a child 5 years of age?

First, it is important to calculate the age of a child in months:

5 years = *12 = 60 months

y = 0. 176*60+7. 241 = 17. 801

Therefore, the predictable age of 3 years old child is 17. 801 kg.

## In Figure 3, some of the actual mean weights represented by the blue line with squares are above the dotted straight line for the novel formula, but others are below the straight line. Is this an expected finding?

Yes, it is the expected finding. Due to the fact that a large standard deviation is always present in children’s group, the mean weight itself is not a reliable value. It is important to prevent errors in children’s’ weight prediction because such errors lead to other mistakes, for example, to errors in the medications’ concentration prescription.

## In Figure a few, the novel method is (Weight within kilograms = (0. 331 × Age group in months) – 6. 868. Very best predicted weight within kilograms for the child 10 many years old?

First, it is essential to calculate the particular age of the child in weeks:

10 many years = 10*12 sama dengan 120 months.

According towards the method in Figure a few, the calculation will certainly be the using:

y sama dengan 0. 331*120-6. 868 = 32. 852

Therefore, the expected weight of ten years old kid will be thirty-two. 852 kg.

## Was the test size of this particular study adequate with regard to conducting simple geradlinig regression?

The sample size has been appropriate to symbolize simple linear regression because a lot more than ten, 000 children had been involved. This test size might be regarded as as large plenty of.

## What are usually potential clinical benefit and something potential medical issue with using the particular three novel formulations presented in Numbers 1, 2, plus 3 inside a PICU setting?

PICU setting is definitely a device for children that need emergency help. Consequently , it is essential to provide all of them with the right dosage of medication. The particular dose of medication is determined depending on child’s bodyweight. Frequently, health treatment providers do not really have time for you to determine the weight. Offered formulas do not really give a precise outcome of weight yet provide a selection of ideals. It could become cited as the disadvantage. Nevertheless , within case of crisis you are able to use this particular range that is much better than nothing. Therefore, these formulas offer an opportunity for required drug usage till children would become stabilized and one’s weight could be measured.
