Home BP Basics

In this video you'll learn how to get reliable blood pressure numbers at home, and stay tuned for the single habit that makes all the difference.

Arm vs Wrist

An automatic upper-arm monitor is the gold standard. It sits over the brachial artery at heart level, giving reliable numbers. A wrist device only works if an arm cuff truly won’t fit, and you must keep the wrist at heart height.

Clinic high limit

Doctors flag a reading of 140 over 90 as high in the clinic. At home, readings tend to be a few points lower, so the home threshold is roughly 135 over 85. Keep this in mind when you log your numbers.

Cuff size

First, find the middle of your upper arm by measuring halfway between shoulder tip and elbow. Wrap a tape around that spot and note the circumference in centimeters. Pick a cuff whose range covers measurement; a too-small cuff reads high, a too-large cuff reads low.

Measuring routine

Avoid caffeine, nicotine, heavy meals or exercise for at least thirty minutes before measuring. Empty your bladder, then sit upright with your back supported, feet flat, and legs uncrossed. Rest quietly for five minutes, keeping the arm you’ll use at heart height on a table.

7-day plan

Take two readings a minute apart each morning before breakfast and medication, and repeat same in the evening. Do this for seven days, but discard the first day’s numbers because they’re often higher due to nervousness. Average the remaining readings to get your blood pressure.

Common mistakes

Pitfalls include placing the cuff over clothing or a rolled-up sleeve, using a cuff that’s too small or too loose, letting the arm hang instead of resting at heart level, and talking or moving while the cuff inflates. Weak batteries can also cause erratic numbers.

The one habit

The one habit that guarantees the most reliable home readings is to always use the same arm, with a properly fitting cuff, after a quiet five-minute rest. Consistency beats all the other tricks.
