Wallis et al reported reference ranges for respiration rate in pediatric patients from 4 to 16 years of age. The authors are from Red Cross War Memorial Children’s Hospital in Cape Town, London School of Hygiene and Tropical Medicine, the University of Plymouth, and St.Mary’s Hospital London.
Patient selection: pediatric patient from 4 to 16 years of age
2.5%ile for respiratory rate =
= (-0.7239 * (age in years at last birthday)) + 21.95
97.5%ile for respiratory rate =
= (-0.6051 * (age in years at last birthday)) + 28.56
mean value =
= (2.5%ile) + (((97.5%ile) – (2.5%ile)) / 2)
