What is the lowest blood pressure a human can have and still be alive?

Question

Any other information on low blood pressure is welcome.

Answer 1

All the above answers are nonsense. Do any of you know anything about medicine at all? You all might try reading the question properly!

I believe that humans have been able to survive at 60/40. Very dangerous bp.

Answer 2

Lowest Blood Pressure

Answer 3

Technically, if a person has ANY measureable blood pressure, that indicates that they have a pulse, and are therefore alive. However, there are certain situations where a person may not be able to recover, in part due to hypotension (low blood pressure).

Normally, we like to see a systolic blood pressure above 90 mm Hg, but that can vary a bit from person to person. I have treated patients with blood pressures as low as 60 mm Hg systolic, who have made a full recovery. I have seen pressures significantly below that, but those patients did not fare so well.

In short, I don't know that anyone can really say if there is a "magic number" for blood pressure, below which mortality is 100%. When treated quickly and aggressively, many cases of hypotension are reversible with something as simple as IV fluid replacement.

Answer 4

Low blood pressure can be dangerous because it decreases the blood's profusion to the vital organs, such as kidneys. I have known people who were still alert and talking with a systolic BP in the low 80's. So, I don't know what the lowest blood pressure a person can have and still survive and I hope I never find out! I would imagine it would vary from one individual to another.

Answer 5

Low blood pressure is known as hypotension/Below the
levels of 115/70 mm Hg for daytime readings in men, and 105/65 in women (women generally have lower pressures than men)


Since most people are aiming to lower their blood pressure from too-high levels, and since exercisers and others in very good health often have low blood pressure, it is not necessarily a "bad" state to be in.

What doctors call low blood pressure is when someone's blood pressure is lower than their NORMAL range. So say your normal blood pressure is 120/60. Then say you have some sort of accident and loose a lot of blood, and now your blood pressure is down to 90/30. You have very low blood pressure now because you are MISSING blood in your body and need to get some added back in.

In the same way, say your typical blood pressure was 200/150. This would be very high blood pressure. But say you had an accident and lost a lot of blood. Your blood pressure could now be down to 120/60. For many people this would be "OK" and healthy. But for YOU this is very low and dangerous, because your body is used to having a much different situation. You would need to be restored to your typical levels.

Causes of unhealthy low blood pressure include:
* dehydration
* injury or trauma
* allergic reactions to drugs

Low blood pressure also happens in older people if they stand up too fast - the blood does not get to their head quickly and they get dizzy. Sitting or lying down can help with this. In the few cases when an individual has a truly low blood pressure, they will have a lack of energy and frequent dizziness.

If your blood pressure is normally below 90/60, it might be good to talk to your doctor about hypotension. Also, if your blood pressure drops 30% or more below your normal blood pressure levels, this is also considered a situation worthy of examining.
The influence of blood pressure on the development of cardiovascular disease and mortality rate beyond 75 years of age has been uncertain. A reported inverse relation to mortality rate noted in the very old could reflect poor cardiovascular health. This report examines the impact of blood pressure on cardiovascular morbidity and mortality rates and all-cause mortality rate in those aged 75 to 94 years.

Answer 6

I agree with Cirric. I personally know a few people who's pressure was 0/0. As long as they can restart it, you're good to go. Even heart transplant patients experience 0/0... When your heart is removed, there's nothing to pressurize your blood. lol

Answer 7

the lowest blood pressure and still be alive would be 100

Answer 8

Hi. 0/0 as long as the heart gets restarted in time.
