orthostatic vital signs
Blood pressure and heart rate measurements taken while lying down, sitting, and standing to assess for postural hypotension in adolescents.
Full Definition
A clinical assessment technique where vital signs are measured in supine, sitting, and standing positions to detect orthostatic hypotension, which can indicate dehydration, eating disorders, or other medical conditions common in adolescents. A drop in systolic blood pressure of 20 mmHg or diastolic of 10 mmHg, or an increase in heart rate of 20 bpm upon standing is considered positive. This assessment is particularly important in adolescent medicine when evaluating for eating disorders, substance use, or medication side effects.
Usage
Usage note: Always specify the position changes and timing when documenting orthostatic measurements.
