What is considered hypotensive for patients aged 10 years or older?

• A. SBP 90 mmHg or higher
• B. SBP < 80 mmHg
• C. SBP < 90 mmHg
• D. Systolic BP cannot be determined

Answer: (C)

For patients aged 10 years or older, hypotension is defined by a systolic blood pressure of less than 90 mmHg. This threshold aligns with adult physiology and serves as a practical indicator of inadequate perfusion and potential shock, prompting rapid assessment and transport. A systolic BP of 90 mmHg or higher is not hypotension, while a value below 80 mmHg indicates more severe hypotension but the standard definition for this age group is <90. If the systolic BP cannot be determined, that does not define hypotension. Ensure accurate measurement with proper cuff size and repeat as needed to confirm.
