A member asked:

How long are you 'out of it' if you pass out from low bp?

A doctor has provided 1 answer

Low blood pressure: May cause you to feel light headed and pass out. This is your body's way to save itself. If you lay flat, more blood can reach your brain and then you may come back awake. How long you are out depends on how long it takes for the blood pressure to come back up in the brain circulation.
