What is the minimum systolic blood pressure for infants older than one month?

• A. Greater than 65 systolic
• B. Greater than 60 systolic
• C. Greater than 70 systolic
• D. Greater than 75 systolic

Answer: (A)

Pediatric blood pressure is age-dependent, so the minimum systolic pressure that indicates adequate perfusion increases as children grow. For infants older than one month, a systolic blood pressure of about 65 mmHg or higher is considered the lower limit of normal. Values below this suggest hypotension and possible shock in this age group, guiding you to escalate care. The other numbers correspond to different ages: 60 mmHg is typically used as the lower threshold for neonates, while higher thresholds like 70 mmHg or 75 mmHg are associated with older children rather than this infant subgroup.
