What does hypotension mean?
when a person is hyper it means high so it is another meaning of
high blood pressure
This is actually incorrect. Hypertension means high blood
pressure. You are asking about hypotension (different word).
The "hypo-" prefix means "low" or "under" (as a hypodermic
needle goes under the skin). Hypotension is low blood pressure, the
opposite of high.
