Blood Pressure 92 Over 40–90: Which Are OK?
With an upper value of 92, the answer depends on your lower number. Here are all readings, sorted by what they mean.
On its own, a systolic (upper) value of 92 mmHg is Ideal (optimal) by the international categories (2023 ESH guideline) and Normal under the 2025 AHA/ACC guideline. The worse of your two numbers decides the category, so a raised diastolic (lower) value moves a 92 reading up, and a lower number below 60 makes it low: below 92/60 it counts as low, from 92/80 it counts as normal, from 92/85 it counts as high normal, from 92/90 it counts as stage 1.
Low blood pressure 92/40 to 92/59
Ideal (optimal) 92/60 to 92/77
Hypertension stage 1 92/90
What to do with a reading of 92 over …
A good upper value. Re-check at least once a year, and use the average of several readings rather than a single one. A lower number below 50 (from 92/49 down) is clearly low: measure again, and if it is confirmed or you feel dizzy, faint or confused, contact a doctor the same day. Keep your readings in a free blood pressure log and read how to measure correctly.
