Blood Pressure
Systolic-Diastolic Pairs Chart

Deviations from Typical Blood Pressure Readings
by Vaughn Aubuchon

What are your adult Blood Pressure pairs?
What are normal blood pressure pairs?
What is normal blood pressure pair range?
What is isolated diastolic hyPERtension?
What is isolated diastolic hyPOtension?
This page attempts to address these questions.



I created my Blood Pressure Range page, by using "typical" Systolic-Diastolic pairs mentioned in the literature. In these typical pairs, such as 120/80, the systolic value divided by the diastolic value is approximately 1.5.

This page addresses those S-D pairs which deviate from the typical values. These non-standard pairs can indicate BP problems, such as Isolated Diastolic Hypertension, and other conditions.

2. Typical Blood Pressure Systolic/ Diastolic Pairs
Represented on An Excel SPREADSHEET

1. Yellow boxes indicate the 3 MOST SIGNIFICANT BP S/D PAIRS reported by Google
    and Bing, for each Systolic multiple of 10,
     using the search term "blood pressure of 120/80", etc., etc.
     255 pairs were checked.
2. The slope from Systolic 40 to Systolic 90 = 1.25
(approximately)
3. The slope of the
RED line line = 1.5
4. The slope from Systolic 100 to Systolic 240 = 2.0
(approximately)
5. The grey area indicates IMPOSSIBLE readings, since the diastolic value is greater
     than the systolic value.
6. The blue area indicates highly IMPROBABLE readings.

1. YELLOW boxes above = the LOWEST diastolic pressure at each systolic pressure
BLUE boxes above = the HIGHEST diastolic pressure at each systolic pressure

2. none = precious few

2. In the literature, there are far more mentions of multiples of 10, than multiples of 5. I believe the main reason for this is that virtually ALL sphygmomanometers are graduated in units of 20. This causes a strong bias to round off to a multiple of 10, and just skip the harder to read 5s. As more and more practitioners are employing automatic digital sphygmomanometer devices, this bias should become less prevalent over time.
