Human Blood Pressure Range Diagram
Textual Description

The 1st Number: Systolic pressure is the blood pressure when the heart muscle contracts.
The 2nd Number:
Diastolic pressure is the blood pressure when the heart is relaxed.

The BP numbers shown in the chart represent "Typical" systolic-diastolic pairs. There are many "non-typical" systolic/diastolic pairs, which I have analyzed statistically at Systolic-Diastolic Pairs.

What is Normal Blood Pressure? Buy and use an automatic blood pressure monitor. Compare your BP reading with the numbers on the chart above. Draw a line from your systolic pressure to your diastolic pressure. Is the slope of the line about the same as shown on the chart?
Where do YOU fit in? What are your risk factors?
Are your blood pressure readings within the normal blood pressure range?
Should you take anti-hypertension medication to lower your blood pressure?

Normal human daily Blood Pressure Range can vary widely, so any single blood pressure monitor reading is not reliable. BP monitor readings must be taken at different times of day, to determine AVERAGE blood pressure levels over time.
What is important is your AVERAGE BP, or MAP (Mean Arterial Pressure) over time.
Or, where are those numbers sitting MOST of the time?
Normal MAP is about 93 mm of mercury.

For the scientists among you: The pressure of 1 mm of mercury = 0.019337 P.S.I. A systolic blood pressure of 2 P.S.I. is good, a systolic blood pressure of 3 P.S.I. is not good.

4. BP Levels Table Notes
(for table directly above)

1. Why did I do this? I searched high and low on the Internet, and I could find nothing like this in one place - a Summary of human BP range, the Averages, and the Comments relating to each BP level.

2. How did I get the numbers? I started with the commonly seen "Systolic/ Diastolic pairs" seen in the literature - 200/120, 160/100, 140/90, 120/80 and 90/60. From there, I interpolated and extrapolated all the other numbers. Note that these are AVERAGE relationships. For instance, instead of 140/90, your BP may be 140/100, or 140/80. Each individual will have a unique systolic-diastolic relationship. If your S/D difference varies significantly from the averages shown above, this can be helpful in assessing your particular cardiovascular condition.

3. Fairly recently, the difference between Systolic and Diastolic pressure, named "
Pulse Pressure", has been gaining interest in the research community. This Pulse Pressure has been found to correlate linearly with heart attack risk - the higher the number, the higher the risk. According to this theory, a BP of 140/ 90 (PP=50) is more desirable than a BP of 140/ 80 (PP=60).
This PP relationship at each pressure appears to be almost linear.

4. As for the comments, I have "averaged" the references made in the literature, since not all doctors agree upon the pressures at which to treat, and how aggressively to treat (multiple medications, type of meds, etc.). You can rest assured that the pharmaceutical companies prefer that you take medication at 135/80, since they sell the meds. Most doctors are not so aggressive. Remember that ALL medications have side effects.
Heart medications have more serious side effects than any other class of prescription drugs.

5. Be aware of the "Circadian Rhythm" cycle. Your Blood Pressure is highly influenced by the time of day. For normal people, the highest BP occurs about midday, and the lowest at about 3-4 AM in the morning. For some people, described as "non-dippers", this early morning BP dip does not occur. For these people, highest blood pressure usually occurs around 6 AM to 9 AM in the morning. Some doctors are not aware of this, and make erroneous assumptions. A non-dipper may see 150/95 in the morning, and 130/85 in the evening. Non-dipping is usually associated with abnormal sleep conditions, such as sleep apnea, heavy snoring, drug and alcohol abuse, etc.

6. One blood pressure reading means very little. The advice to "Have your blood pressure checked once a year" is useless. What time of day? Had you eaten less salty foods recently? Were you relaxed that day, when you are usually much more stressed? Had you recently exercised vigorously? You must check your BP far more often than once a year, especially if you show "borderline" readings. I can produce a very low, or very high blood pressure AT WILL, based upon what I do during the 24 hours prior to the measurement.

7. Beware of "white coat syndrome", which results in a much higher BP reading than normal, due to the authoritative doctor, the foreboding, sterile exam room, and the smells such as alcohol and disinfectant. All this is not relaxing. Some unaware doctors may prescribe medication, when in fact, you don't need it at all. As soon as you leave the office, your BP returns to normal. This is another great reason to use your own automatic BP wrist monitor, so that you come to know your own body, and the effects of stress, food, mood, sleep, and time of day.

8. MAP = Mean Arterial Pressure. Three formulas are used to compute MAP. All three produce very similar results.
Above, I used Method #1 -
MAP = DP + (1/3 (SP - DP))
Ideal Mean Arterial Pressure is defined as 93 mm of mercury, which corresponds to 120/80.

Alternative Method #2 -
Also, MAP = (2/3 DP) + (1/3 SP)

Alternative Method #3
MAP = ((2*DP) + SP) / 3

where SP= Systolic Pressure,
and DP= Diastolic Pressure

Updates

UPDATE - ADDENDUM Jan. 30, 2011:
1. Recently, this page content has been scraped (stolen) by health-heart.net, and hosted by Bluehost.com - Click here for a description of this page theft.

2. Recently, this page has been accused of presenting "old" numbers. The US National Institute of Health still recommends the numbers shown above. Here, I present official government-blessed data.
Other medical organizations have issued new numbers recently. I believe that one must consider the source. Do the members of the group have an interest in seeing increased drug sales? Individuals with pharmaceutical connections often want people to start taking blood pressure medications, who really don't need them at all. For some, it is all about drug sales, not about your health.

3. This page and large graphic have been online since Oct. 2003, and updated hundreds of times over the last 9 years.

UPDATE - May 25, 2013 -
Redrew the main BP graphic (rev.19).
Reformatted for your iPhone.
I also separated the suggested foods, vitamins and minerals from the chart format, and created a separate table for them, so as to make them appear "less directly related" to actual pressure - many factors are at play. The chart is thus more focused toward pressure, and less cluttered with extraneous, perhaps speculative information.
