💡 Editor's note: The Omron M3 Comfort is a widely used home monitor and appears on the BIHS validated list. Validation matters, as not every monitor on sale has been independently tested for accuracy.

Omron M6 Comfort Upper-Arm Monitor

Step-up upper-arm model

Upper-arm monitor from Omron's M6 range. Check the current specification (memory, cuff range and connectivity) on the product page before buying. The older M6 AC has been discontinued.

💡 Editor's note: Keeping a written or app-based log of your readings makes it easier to share a history with your GP or pharmacist. Check which models support this before upgrading.

Omron Large Cuff for M3/M6 32-42cm

Cuff size guide

If your upper arm circumference is over 32cm, you need the large cuff. Wrong cuff size is the most common cause of inaccurate home readings.

💡 Editor's note: An incorrectly-sized cuff gives falsely high or low readings. Measure your upper arm circumference (middle of bicep) — standard cuffs fit 22-32cm; large cuffs fit 32-42cm.

What to look for

Upper arm monitors are more accurate than wrist monitors — upper-arm monitors are generally preferred for home use. Look for validation by the BIHS (British and Irish Hypertension Society) and check the model number against its list at bihsoc.org. Avoid wrist monitors unless you have a specific reason (e.g. very large upper arm).

Frequently asked

?

What is a normal blood pressure reading?

The NHS describes ideal blood pressure as between 90/60 and 120/80 mmHg. High blood pressure is 140/90 or higher when checked by a healthcare professional, or 135/85 or higher when checked at home. Rest quietly for 5 minutes before measuring, and speak to your GP or pharmacist about what your readings mean.

?

How often should I measure at home?

NHS and NICE guidance: take a reading, wait one minute, then take a second, and do this once in the morning and once in the evening. Your GP will tell you how many days to keep this up (commonly 4 to 7 days, with the first day usually discarded before averaging). Always sit quietly for 5 minutes before measuring.
