How do you test for postural drop?

Your doctor will diagnose orthostatic hypotension if you have a drop of 20 millimeters of mercury (mm Hg) in your systolic blood pressure or a drop of 10 mm Hg in your diastolic blood pressure within two to five minutes of standing, or if standing causes signs and symptoms. Blood tests.

How do you test for orthostatic hypotension?

1 Have the patient lie down for 5 minutes. 2 Measure blood pressure and pulse rate. 3 Have the patient stand. 4 Repeat blood pressure and pulse rate measurements after standing 1 and 3 minutes.

Does orthostatic hypotension go away?
