Weight-estimation formulas
APLS (Luscombe & Owens 2007 / APLS-UK 2016)
• 0-12 months: (0.5 × age in months) + 4
• 1-5 years: (2 × age in years) + 8
• 6-12 years: (3 × age in years) + 7
Best Guess (Tinning & Acworth 2007)
• 1-11 months: (age in months + 9) / 2
• 1-4 years: 2 × (age in years + 5)
• 5-14 years: 4 × age in years
Broselow tape (length-based) is most accurate when available.

Bedside

Weight-based pediatric reference. Always verify against institutional protocols.

Neonatal Assessment

GA classification, birth weight assessment (AGA/SGA/LGA), and prematurity category. Fenton 2013 / WHO.

NRP Resuscitation Pathway

AHA Neonatal Resuscitation Program 2020. Static visual pathway — enter weight to calculate drug doses.

Apgar Score

Assess at 1 and 5 minutes. If <7 at 5 min, repeat every 5 min up to 20 min. Apgar is a description — never delay resuscitation waiting for a score.
