The rules and numbers that recur on the Neonatal Pediatric Transport exam. Skim it before
test day, then prove it with practice questions.

Exam facts

  • 125 questions (100 scored, 25 unscored), 2 hours
  • Transport Core Knowledge 48%, Neonatal 26%, Pediatric 26%

Transport physiology (the heart of the core section)

  • Boyle’s law — gas expands as pressure drops with altitude:
    pneumothorax, bowel gas, and ETT cuffs all enlarge in flight.
  • Dalton’s law — the partial pressure of oxygen falls at altitude,
    worsening hypoxia.
  • Stressors of transport — thermal, noise, vibration, gravitational
    (G) forces, and decreased humidity.

Neonatal stabilization — S.T.A.B.L.E.

Sugar & safe care, Temperature, Airway,
Blood pressure, Lab work, Emotional support.
Keep glucose above ~45–50 mg/dL and the neonate in a thermoneutral environment.

Key medications

  • Prostaglandin E1 — keeps the ductus arteriosus open in
    duct-dependent lesions (watch for apnea).
  • Surfactant — for respiratory distress syndrome in preterm neonates.

Pediatric airway quick math

  • Uncuffed ETT size ≈ (age/4) + 4; cuffed ≈ (age/4) + 3.5
  • ETT insertion depth at the lip ≈ ETT size × 3 (a 4.0 tube → ~12 cm)

Normal vitals by age

Age Heart rate Respiratory rate
Neonate 120–160 40–60
Infant 100–160 30–60
Toddler / preschool 80–130 24–40
School age 70–110 18–30

Knowing these cold frees your attention for the judgment the exam is really testing.
