Postural hypotension indicates a drop in blood pressure when a person moves from a supine to a sitting or standing position.
(1) The patient rests in a supine position for at least 5 minutes.
(2) The systolic blood pressure is taken while the patient is in the supine position.
(3) The systolic blood pressure is taken immediately as the patient assumes a sitting position.
• A drop of more than 10 mm Hg in the systolic blood pressure as the person moves from a supine to a sitting position indicates postural hypotension.
