Which statement correctly describes the pediatric hypotension thresholds across age ranges?

• A. Neonates SBP <60 mmHg; Infants SBP <70 mmHg; 1-10 years SBP <70 + (2 x age in years).
• B. Neonates SBP <60; Infants SBP <60; 1-10 years SBP <70.
• C. Neonates SBP <50; Infants SBP <70; 1-10 years SBP <70 + (2 x age).
• D. Neonates SBP <70; Infants SBP <70; 1-10 years SBP <70 + (2 x age)

Answer: (A)

Pediatric hypotension is defined by age-specific systolic blood pressure thresholds. Neonates are considered hypotensive if SBP is below 60 mmHg, infants below 70 mmHg, and children aged 1 to 10 years have a threshold that increases with age: SBP below 70 plus 2 times the child’s age in years. For example, a 5-year-old would be hypotensive if SBP < 70 + (2×5) = 80 mmHg, and a 10-year-old if SBP < 70 + (2×10) = 90 mmHg. This approach reflects how normal BP rises with age and helps identify shock early across different ages. Other options don’t fit because they either apply the same fixed threshold across ages or misstate the neonatal threshold (e.g., using <70 for neonates or <50/incorrect fixed values).
