What is APLS formula?
Calculation using the ‘APLS’ formula (weight = [age + 4] × 2) is one very common method. Studies on its validity in developed countries suggest that it tends to under-estimate the weight of children, potentially leading to errors in drug and fluid administration.
How do you calculate a child’s height by age?
Birth length doubles by 3.5 years, and triples by 12 years. The formula estimating average height of normal children aged 2 – 10 years was, height (cm) = age (yr) x 6.5 + 76 (cm).
How do pediatrics determine weight and height?
IV. Calculation
- Step 1: Define height age. Determine age when 50% children reach patient’s height.
- Step 2: Define target weight. Locate 50th percentile Weight for Height Age (Step 1)
- Step 3: Calculate Weight for Height Age. Calculation = (Actual weight)/(Target weight) x 100.
What should I weigh for my age and height?

What is the APLS formula for weight calculation?
At the Paediatric Emergency Department, Eric Williams Medical Sciences Complex, the Advanced Paediatric Life Support (APLS) formula is used to estimate weight in children from one to ten years of age. The original formula is as follows: Weight (kg) = (Age (years) + 4) × 2 [ 2 ].
Is the Luscombe and Owens formula more accurate than APLS?
The Luscombe and Owens formula was slightly more accurate in predicting weight than the APLS formula overall with a mean difference of −0.4 kg (95% limits of agreement 6.9 to −6.1) (Table 1 ).
What is the best Formula to calculate weight and age?
Using linear regression analysis, the best formula to describe weight and age was as follows: Weight = 2.40 × age + 8.25. This formula, however, is impractical for use in the Emergency Department due to difficulty for quick calculation.
