supine to standing test

The supine-to-standing test assesses how your body reacts when switching from lying down to standing. Initially, your blood pressure and heart rate are measured while lying flat (supine). Then, you stand up, and these measurements are repeated at intervals. The test helps identify issues like orthostatic hypotension, where blood pressure drops upon standing, causing dizziness or fainting. It's useful for diagnosing problems related to blood flow regulation and autonomic nervous system function, ensuring that your body responds appropriately to positional changes.
