Orthostatic hypotension (or postural hypotension) is a drop in blood pressure upon standing. One definition (AAFP) calls for a systolic blood pressure decrease of at least 20 mm Hg or a diastolic blood pressure decrease of at least 10 mm Hg within 3 minutes of standing. [31]
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
On the other end of the spectrum is the vasodepressor response, caused by a drop in blood pressure (to as low as 80/20) without much change in heart rate. This phenomenon occurs due to dilation of the blood vessels , probably as a result of withdrawal of sympathetic nervous system tone.
An example of this phenomenon is measurement of blood pressure using the "pulse obliteration method" with a sphygmomanometer. At resting state the arterial critical closing pressure is ~ 20 mmHg . Critical closing pressure in arteries is higher than the mean vascular filling pressure that develops after death (~7 mmHg).

On standing the person will experience reflex tachycardia (at least 20% increased over supine) and a drop in blood pressure. [9] Hypoadrenergic orthostatic hypotension occurs when the person is unable to sustain a normal sympathetic response to blood pressure changes during movement despite adequate intravascular volume.
In recent years, more adults between the ages of 45 and 64 have been dying from strokes, according to a new report from the Centers for Disease Control and Prevention (CDC). Stroke occurs when ...
Neurogenic shock is diagnosed based on a person's symptoms and blood pressure levels. Neurogenic shock's presentation includes: [7] [8] - warm and pink skin - labored breathing - low blood pressure - dizziness - anxiety - history of trauma to head or upper spine. - if the injury is to the head or neck, hoarseness or difficulty swallowing may occur.
