If you’re able to wear an arm-based blood pressure monitor, you should: When it comes to at-home monitoring, the AHA only recommends the use of upper-arm cuff oscillometric devices that have successfully passed validation protocols.

Wrist- and finger-based blood pressure monitors typically aren’t as accurate, Yale Medicine cardiologist Erica S. Spatz, MD tells CNET.

However, there are some circumstances in which a wrist- or finger-based blood pressure monitor might be preferable to an arm-based monitor, such as if you have a disability that prevents you from affixing an arm-based monitor or if your arms are too large to fit in an arm cuff .

The Qardio Arm wireless blood pressure monitor has passed British and Irish Hypertension Society validation protocols.

    New Technology To Improve Reading Accuracy Of Home Blood Pressure Monitoring

    In order to measure BP accurately, the cuff must be wrapped correctly and proper posture of the patient during the measurement is essential. Users can find it difficult to wrap the cuff in the correct position, especially if they are inexperienced. If the cuff is wrapped incorrectly then the result is less accurate. In addition, irregular pulses due to arrhythmias lead to inaccurate BP readings. Home monitoring devices equipped with automated cuff wrapping and a display indicating correct positioning have been introduced. These devices can detect irregular pulses that cause inaccurate BP readings. Moreover, they detect noises and wave pulses within the cuff that are caused by arm movements. These device functions may help provide more accurate BP readings.

    Choosing And Using A Home Blood Pressure Monitor

    There are dozens of home blood pressure monitors on the market, ranging in price from about $50 to $100. For best accuracy and ease of use, buy one with a cuff for the upper arm that automatically inflates and that automatically records the pressure. Models that store readings for a week or two can simplify record keeping.

    Be sure to choose one with the correct cuff sizethe inflatable part should completely cover at least 80% of your bare upper arm. Test it in the store to be sure it’s easy to use. Note that the American Heart Association doesn’t recommend wrist or finger home blood pressure monitors, as they are not as reliable.

    What Equipment Do I Need To Measure My Blood Pressure At Home

    How to use a blood pressure monitor at home

    To measure your blood pressure at home, you can use either an aneroid monitor or digital monitor. Choose the type of monitor that best meets your needs. Look at the following features when you select a monitor.

    • Size: The right cuff size is very important. The cuff size you need is based on the size of your arm. You can ask the doctor, nurse, orpharmacist to help you. Blood pressure readings can be wrong if your cuff is the wrong size.
    • Price: Cost may be a key factor. Home blood pressure units vary in price. You may want to shop around to find the best deal. Keep in mind that pricey units may not be the best or most accurate.
    • Display: The numbers on the monitor should be easy for you to read.
    • Sound: You must be able to hear your heartbeat through the stethoscope.

    Tests show that finger and wrist devices do not always provide correct measurements. These devices are sensitive to placement and body temperature. They also are expensive and can cost more than $100.

    Aneroid monitor

    The aneroid monitor manually checks your blood pressure. It has a gauge that you read by looking at a pointer on the dial. The cuff goes around your upper arm and you squeeze a rubber bulb to inflate it by hand.

    Digital monitor

    Inflation of the cuff is either automatic or manual, depending on the model. Deflation is automatic. Digital monitors are good for hearing-impaired patients, since there is no need to listen to your heartbeat through the stethoscope.

    Only a doctor can diagnose you with high blood pressure. Contact your doctor if you have high readings for several days. Be sure to take your blood pressure log with you to the visit.

    Hypotension is low blood pressure. This occurs when your systolic pressure is consistently below 90 or is 25 points below your normal reading. Contact your doctor if you have low readings. Hypotension can be a sign of shock, which is life threatening. Call your doctor right away if you are dizzy or lightheaded.

    What Is A Blood Pressure Monitor

    Blood pressure monitors are digital medical devices that allow people to check their blood pressure levels and track their readings anywhere at any time, often independently. While many medical professionals use a stethoscope to listen to your blood pressure manually, these monitors measure your blood pressure with oscillometric technology, measuring the vibration of blood traveling through your arteries and converting that movement into digital readings.

    Blood pressure monitors often come with the monitor itself and a cuff, either for your upper arm or wrist. The American Heart Association recommends using upper arm cuffs, as they provide more accurate readings than wrist cuffs.

    Compliance And Improvement Of Blood Pressure Control

    Incorporation of HBPM into routine management of patients with uncontrolled hypertension may improve BP control. Several meta-analyses have shown that compared with usual care, the use of HBPM is associated with significant reductions in systolic and diastolic BP, as well as reductions in antihypertensive medication and therapeutic inertia, defined as unchanged medication despite elevated BP. While most studies have focused on white populations, some studies have looked at ethnically diverse adults with uncontrolled BP and high-risk patients and with baseline BP of at least 130/80 mmHg) from clinics in low-income, medically underserved communities. Studies are also ongoing in stroke and at-risk groups.

    Some studies suggest that HBPM may contribute towards medication adherence in hypertensive patients, although others have not reached this conclusion. NICE guidelines still recommend ABPM where possible.

    Monitoring Blood Pressure At Home

    If you have been diagnosed with high blood pressure, known medically as hypertension, your doctor may recommend that you use a home monitor to check your blood pressure between visits.

    High blood pressure has been called the “silent killer.” The name may seem grandiose, but it’s unfortunately accurate: High blood pressure has no symptoms and it can lead to life-threatening illnesses, strokes, and heart attacks. While 50 million people in the U.S. are estimated to have high blood pressure, as many as a third of them may not know it.

    If you have been diagnosed with high blood pressure, known medically as hypertension, your doctor may recommend that you use a home monitor to check your blood pressure between visits. Despite what you might think, devices that you can buy in the drugstore or at the mall can be reliable, accurate, and affordable. But there are a lot of monitors out there, and it’s crucial to get a good one.

    What Kind Should I Use

    Of the different types available, Sheldon Sheps, MD, emeritus professor at the Mayo Clinic in Minnesota, says that you should get only an electronic one with a digital display. The other kinds — such as aneroid or mercury devices — require training with a stethoscope to get accurate readings.

    “The automated electronic equipment is very simple to use and very reliable,” says Michael Weber, MD, Professor of Medicine at the SUNY Health Science Center in Brooklyn. “They’re so accurate that many clinical trials are now actually using the same blood pressure machines that you can buy from the drugstore.”

    However, of these electronic devices, Weber and Sheps urge you to get a device that measures your blood pressure with a cuff around the arm. Don’t buy one that works on the wrist, and definitely avoid finger blood pressure monitors, since they are especially unreliable.

    A good device costs between $40-$60, although models with additional features are pricier. Some offer a self-inflated cuff, which saves you the trouble of pumping it up yourself. Other devices have a memory of previous readings, and some even print a record each time you use it. Sheps observes that a company’s line of devices will often all use the same microchip, so a no-frills model is often as accurate as a more expensive one made by the same company.

    And don’t forget to shop around. “The same device may cost twice as much at a medical supply store as it does at a chain store,” says Sheps.
