Blood Pressure Monitors and Cuffs

Which cuff style suits you: upper arm, wrist or fingertip?

The cuff style is the biggest choice. Upper-arm monitors are the style most commonly advised for home use, because the cuff sits naturally at heart level and gives steadier readings. Wrist models are compact and travel easily but are more sensitive to arm position, so you must hold the wrist at heart height and keep still. Fingertip devices are the most sensitive to position and movement. Operating mode also varies: automatic units inflate themselves, while manual ones use a hand bulb and need a stethoscope.

Cuff size, memory and power: where wrong readings come from

Measure around the bare upper arm midway between shoulder and elbow, then pick a cuff whose stated range includes it. Listings quote ranges in inches or centimeters, and some include two cuffs. A cuff that is too small reads high, and one that is too large reads low. Memory for several readings and for two users helps you keep a log. Power is battery, usually AA, or corded or USB, so check what is supplied.

Questions about Blood Pressure Monitors and Cuffs

How do I measure my arm for the right cuff?

Wrap a tape around the bare upper arm halfway between shoulder and elbow and read the circumference. Choose a cuff whose range includes that number. An undersized cuff overestimates pressure and an oversized one underestimates it.

Is a wrist monitor as accurate as an upper-arm one?

It can be if used correctly, but wrist models are sensitive to arm position: the wrist must be at heart height and still. Upper-arm models are less fussy, which is why they are generally advised first.

Do I need a monitor with memory?

Memory helps if you track readings over days or share the device, so look for saved readings and separate user slots. Without it, write each result in a log with the date and time to show your doctor.
