Blood Pressure 191 Over 48–160: Which Are OK?
With an upper value of 191, the answer depends on your lower number. Here are all readings, sorted by what they mean.
On its own, a systolic (upper) value of 191 mmHg is Hypertension stage 3 by the international categories (2023 ESH guideline) and Severe hypertension under the 2025 AHA/ACC guideline. The worse of your two numbers decides the category, so a raised diastolic (lower) value moves a 191 reading up: every listed reading stays in the same category. Readings below 191/131 have a pulse pressure above 60 mmHg — a wide gap that is common after 60 and worth mentioning to your doctor.

↓ = the lower number is below 50: these readings count as stage 3 by the upper number, but the low lower number needs checking — see each page.
What to do with a reading of 191 over …
Sit quietly for 5 minutes and measure again. If it is still 180/110 or higher, contact a doctor the same day — and call 911 (US) or your local emergency number right away if you have chest pain, shortness of breath, back pain, numbness or weakness, vision or speech problems, confusion or a severe headache. A lower number below 50 (from 191/48 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.
