In my hospital it's called postural hypotension.
Postural Hypotension or Orthostatic Hypotension
Dizziness when standing occurs due to low blood pressure. The body is at rest and upon standing the heart needs to pump faster to supply more pressure. The dizziness is the moment leading up to when the proper blood pressure is reached. This is not normally something to be concerned about. However if it continues to happen, you should get your blood pressure checked at your doctor.
Someone may pass out when they stand up due to a condition called orthostatic hypotension. This occurs when blood pressure drops suddenly upon standing, leading to reduced blood flow to the brain. Factors such as dehydration, prolonged sitting, or certain medications can contribute to this drop in blood pressure. When the body fails to quickly adjust to the change in posture, it can result in fainting or lightheadedness.
I am not a doctor, but from my experience it can. I have low blood pressure in generall and when I become really sad I feel faint, cold, my nose feels strange, same as when bloodpressure falls when standing up to quickly, sometimes I even shake as if I was really cold.
No, this blood pressure is actually within the new guidelines for optimum blood pressure (110/70). A blood pressure that is too low would be symptomatic, such as feinting or lightheadedness when standing.
Sudden change in blood pressure.
When a person rises quickly from a prone to standing position, they may experience a drop in blood pressure due to a sudden change in position. This can lead to lightheadedness or dizziness known as orthostatic hypotension. It is important to rise slowly to allow the body time to adjust to the change in position.
In most cases, body position has very little effect on blood pressure. In many cases, the blood pressure will rise a little as a result of the heart rate going up when sitting or standing compared to lying down. Some people have an imbalance in their Autonomic Nervous System, which controls constriction and dilation of blood vessels and may find that their blood pressure is lower when standing as opposed to when lying down or sitting.

In blood pressure nomenclature, where blood pressure is denoted xxx/yy, "xxx" is called the systolic blood pressure, whereas "yy" is called the diastolic blood pressure. A normal average blood pressure is 120/80, across the population. Yours may be slightly higher or lower than this average.
If you mean, what is the lowest blood pressure, then the answer is around 60 in an average person. Blood pressure is relatively consistent through out the body, so the lowest pressure would be seen when the heart is resting (also know as diastolic blood pressure).
The normal blood pressure for a standing horse is 120/70 mmHg, however this may vary between different horses.
