International categories: European Society of Hypertension (ESH) 2023, office readings. Home readings use lower thresholds — hypertension from an average of 135/85. A reading with one raised and one low number counts by the raised one.
Pulse pressure and mean arterial pressure
A pulse pressure of 25 mmHg is slightly narrow, just below the usual range of 30–60 mmHg. Measure again to make sure the reading is right. Mean arterial pressure — the average pressure perfusing your organs — is about 36 mmHg. That is low: below about 65, organs such as the brain and kidneys can be under-supplied. If you feel faint, confused, short of breath, or cold and clammy, act on it now.
Measure it right
- No caffeine, exercise or smoking for 30 minutes; empty your bladder.
- Sit with back supported, feet flat, for 5 minutes. Don't talk.
- Upper-arm cuff of the right size on bare skin, arm supported at heart level.
- Two readings a minute apart, morning and evening, for 7 days — use the average.
