Why you should get a wireless blood pressure monitor

There’s a reason why your doctor takes your blood pressure nearly every time you step into their office: It’s a quick and painless way to get a snapshot of your heart health. But that doesn’t mean it’s the best way.

That’s because blood pressure can change based on a variety of factors, including pain, temperature, physical exertion and even doctor’s visits.

So how do you avoid these potentially false positives and false negatives? Do DIY testing.

If you can’t imagine yourself sitting at your kitchen table manually pumping up a blood pressure cuff, don’t worry. The newest crop of over-the-counter monitors are wireless, digital and easier than ever to use. Here’s what you need to know before buying one.

How do wireless blood pressure monitors work?

Every time your heart beats, it pumps blood throughout your circulatory system, putting pressure on the walls of your blood vessels. Blood pressure monitors typically measure the force of this pressure in millimeters of mercury (mmHg) using something called a sphygmomanometer.

A sphygmomanometer inflates a rubber cuff that’s wrapped around your finger, wrist or upper arm until no blood can flow through the brachial or radial artery. When the air is slowly released from the cuff, blood starts to flow through the artery again, creating a pounding sound that can be detected with a stethoscope or an algorithm.

Your systolic blood pressure is the pressure reading noted when this pounding sound first starts. Your diastolic blood pressure occurs when it stops.

Digital wireless blood pressure monitors will display your results on the main unit, in an accompanying smartphone app — where you can view graphs and trends and sync the data with additional apps such as Apple Health — or both.

The measurement is written as two numbers. The top is your systolic blood pressure (the pressure when your heart beats). The bottom is your diastolic blood pressure (the pressure between beats). A healthy blood pressure range is from 90/60 to 120/80 mmHg.

Who are wireless blood pressure monitors for?

The American Heart Association (AHA) and other health organizations recommend that people with high blood pressure measure it at home, a practice known as self-measured blood pressure (SMBP) monitoring or home blood pressure monitoring (HBPM).

Blood pressure naturally rises and falls throughout the day but chronically high readings (at least 130/80 mmHg) can be a sign that your heart is strained and working too hard, a condition known as hypertension. High blood pressure often has no obvious signs or symptoms, which is why it’s known as the “silent killer.” Over time it can increase your risk of heart attack, stroke and heart and kidney failure.

SMBP can help rule out “white coat hypertension,” in which a person’s blood pressure is high in the doctor’s office but normal in daily life, and masked hypertension, in which a person’s blood pressure is normal in the doctor’s office but elevated in daily life.

“Taking blood pressure as part of every routine office visit is, at best, not necessary, and at worst, may lead to inferences about a person’s hypertension status that are incorrect,” says Yale Medicine cardiologist Erica S. Spatz, MD. “Ideally we would be using home blood pressure readings to screen for and monitor hypertension. These readings are more indicative of a person’s true hypertension status and better associated with the outcomes we care about, namely heart disease, stroke and kidney disease.”

It can also inspire a stronger sense of responsibility for your health and better control over your situation. Research shows that adults with hypertension who monitor their blood pressure at home (with or without additional support) are more likely to successfully lower their readings compared with usual care.

But you don’t have to have hypertension to benefit from using wireless blood pressure monitors. They can also detect hypotension, or chronically low blood pressure (below 90/60 mmHg, though this can vary from person to person). In some people, hypotension can cause no problems. In others, it can signify that something more serious, like heart failure or severe infection, is going on, especially if it’s accompanied by symptoms such as dizziness, fainting or nausea.

“In the elderly or in people who are frail, we are particularly concerned about falls,” says Spatz. “So it’s important to assess for low blood pressures, especially with standing.”

Whether you have high or low blood pressure, SMBP monitoring can help both you and your doctor catch issues early and track whether any medication or lifestyle interventions are working, all while cutting back on office visits…..Read More>>
