What are normal vital signs for 6 months to 3 years?

• A. HR: 90-160, RR: 20-40, SBP: >70
• B. HR: 100-180, RR: 25-50, SBP: >60
• C. HR: 60-100, RR: 15-25, SBP: >85
• D. HR: 80-120, RR: 20-30, SBP: >75

Answer: (A)

In this age range, vital signs run higher than adults, reflecting a faster metabolism and smaller cardiovascular reserve. For children from 6 months up to about 3 years, a typical resting heart rate can span roughly 90–160 beats per minute, which covers normal variation from quiet to activity or fever. Breathing rate is usually about 20–40 breaths per minute, again allowing for normal fluctuations with activity or distress. Blood pressure is lower than adults, and a systolic value above around 70 mmHg is generally considered acceptable for perfusion in this group (with more precise practice noting the lower limit is roughly 70 + 2 per year of age; for this span that still sits around the 70s to 80s range).

The option that matches these pediatric norms best is the one with heart rate 90–160, respiratory rate 20–40, and systolic blood pressure greater than 70. This aligns with how pediatric vital signs are taught for early childhood in EMS settings.

In practice, remember that fever, crying, and dehydration can push vitals higher, while calm, well-oxygenated kids may be on the lower end of the ranges. Use trends and overall perfusion (capillary refill, color, mental status) along with vitals to assess stability.
