A very small number of Queensland Health facilities have their own EWS charts in use. [25] The family of charts includes:
Reference ranges for blood pressure Stage Approximate age Systolic Diastolic Range Typical example Range Typical example Infants 1 to 12 months: 75-100 [33] 85: 50–70 [33] 60 Toddlers 1 to 4 years: 80-110 [33] 95: 50–80 [33] 65 Preschoolers 3 to 5 years: 80-110 [33] 95: 50–80 [33] 65 School age 6 to 13 years: 85-120 [33] 100: 55–80 [33 ...
Normal values of ESR have been quoted as 1 [24] to 2 [25] mm/h at birth, rising to 4 mm/h 8 days after delivery, [25] and then to 17 mm/h by day 14. [24] Typical normal ranges quoted are: [6] Newborn: 0 to 2 mm/h; Neonatal to puberty: 3 to 13 mm/h, but other laboratories place an upper limit of 20. [26]
With the infant lying supine, the examiner adjusts the infant's head to the midline and supports the infant's hand across the upper chest with one hand. The thumb of the examiner's other hand is placed on the infant's elbow. The examiner tries to pull the elbow gently across the chest, feeling for the resistance.
