What are orthostatic vital signs?

• A. Vitals taken to evaluate the body's response to position changes
• B. Vitals measured during sleep
• C. Vitals assessed only for standing patients
• D. Only heart rate is recorded

Answer: (A)

Orthostatic vital signs involve measuring blood pressure and heart rate as the body changes position, typically from lying down to standing. This tests how the cardiovascular system responds when gravity shifts blood toward the legs. If the readings drop significantly after standing—for example, a notable decrease in systolic BP (about 20 mmHg or more) or diastolic BP (about 10 mmHg or more) within a few minutes, sometimes with a compensatory increase in heart rate—this points to orthostatic hypotension. The procedure uses measurements in more than one position (usually supine and standing) and both BP and HR, not just one position or just heart rate, and it isn’t limited to sleep or to standing alone.
