Blood Pressure Monitors Explained
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.

How Accurate Are Smart Watch Blood Pressure Monitors
Smart watches are becoming increasingly popular as people look for ways to track their fitness and activity levels. One of the most popular features of these devices is the ability to track blood pressure. But how accurate are these devices? There is some debate on the accuracy of smart watch blood pressure monitors. Some studies have found them to be accurate, while others have found them to be less so. A study published in the Journal of the American Medical Association in 2016 found that four out of five smartwatch blood pressure monitors were accurate when compared to a traditional blood pressure cuff. However, another study published in the same journal in 2017 found that only around half of smartwatch blood pressure monitors were accurate. This study also found that accuracy varied depending on the device and the person using it. So, the accuracy of smart watch blood pressure monitors is still somewhat up for debate. However, if youre looking for a way to track your blood pressure, these devices may be worth considering.
Should Your Blood Pressure Readings Be The Same On Both Arms
No, you dont need to have the same blood pressure for both arms. Although it is necessary for the blood pressure to be within the ideal blood pressure range, it will present the need for a further appointment with a professional.
But besides this particular, one can have different BP readings on both arms due to the individual physiology. However, if the pressure variation is too high, your doctor may ask for further diagnosis.

Best Smart Watch Blood Pressure Accuracy
There are a few different factors that can affect the accuracy of a smart watchs blood pressure readings. The type of sensor used, the placement of the sensor on the wrist, and the persons own blood pressure can all play a role. That said, some smart watches are more accurate than others. The Apple Watch, for example, has been found to be quite accurate when it comes to blood pressure readings.
Using a wristwatch or other device that can measure blood pressure without a cuff may be beneficial in providing more frequent and accurate readings of blood pressure. A pair of popular cuff-free devices were tested: the Everlast smartwatch and the BodiMetrics Performance Monitor. Biometric measures systolic and diastolic measurements can only be found in the Everlast watch, whereas the DBP is measured in the Bodimetrics. Mireille Mhealth collaborates with us at Uhealth.

If You Get A High Blood Pressure Reading
- A single high reading is not an immediate cause for alarm. If you get a reading that is slightly or moderately higher than normal, take your blood pressure a few more times and consult your health care professional to verify if there s a health concern or whether there may be any issues with your monitor.
- If your blood pressure readings suddenly exceed 180/120 mm Hg, wait five minutes and test again. If your readings are still unusually high, contact your doctor immediately. You could be experiencing a hypertensive crisis.
- If your blood pressure is higher than 180/120 mm Hg and you are experiencing signs of possible organ damage such as chest pain, shortness of breath, back pain, numbness/weakness, change in vision, difficulty speaking, do not wait to see if your pressure comes down on its own. Call 911.
Why Are Wrist Blood Pressure Monitors Less Accurate
There are two reasons that wrist blood pressure monitors are less accurate than upper arm monitors. The first reason is the anatomy of your wrist itself. The blood vessels in your wrist are more narrow and sit closer to your skin than the blood vessels in your upper arm. This makes it harder to get an accurate reading on your wrist.
The other major reason is user error. While wrist monitors might seem like the easiest home monitors to use, its actually difficult to position them correctly. Many people assume that you can just place a wrist monitor on your wrist and hit a button, but thats not the case.

Best Overall: Omron Upper Arm Gold Blood Pressure Monitor
Stores 100 data sets per user
Results available in under 30 seconds
Only supports two users
Bluetooth feature does not provide much additional information
What do buyers say? 90% of 2,900+ Amazon reviewers rated this product 4 stars or above.
When we looked at our most important attributes: ease of use, fit, and data display, the Omron Upper Arm Gold Blood Pressure Monitor received a five out of five in every category. We found that it was not only easy to fit and position on your arm, but it gave extremely clear, straightforward data in less than a minute.
The Omron Gold only requires two steps to set up: insert the four included AA batteries and attach the cuff to the monitor. The cuff itself is large enough to accommodate a range of arm sizes, but the most impressive feature of this device is how straightforward its instructions are. Once the cuff is around your arm, press the start button and wait for about 30 seconds until your blood pressure and heart rate reading appear on the screen.
While this monitor is great for quick readings and taking on the go , its Bluetooth feature is a bit clunky and difficult to navigate easily. We ultimately found that was a fair trade off for a device so versatile and easy to use, thus receiving our vote for Best Overall blood pressure monitor.

Dont Rely On Wrist Blood Pressure Monitors
Wrist blood pressure monitors have been shown to be inaccurate in a number of studies. The American Heart Association recommends that blood pressure readings be performed on a non-waist or finger monitor rather than on a wrist or finger monitor due to their lower reliability. There may be a variety of reasons why wrist blood pressure monitors fail to be precise. For example, the cuff size and placement on the arm can influence how the reading is performed. Furthermore, it is possible that the monitor will not be calibrated properly, which can result in inaccurate readings. Blood pressure readings should be taken from the arm with the cuff placed at the top of the arm and the probe at the bottom of the elbow, according to most experts. As a result, the monitor can measure blood pressure in this manner.

Use Care And Maintenance
For the most accurate blood pressure readings, you need to test consistently using a properly fitting cuff. It should be snug but not tight according to our physician sources, a poorly fitting cuff can distort your reading. Many blood pressure monitors come with cuffs of different sizes, so choose the one that fits the circumference of your arm.
Its also important to test under controlled conditions, ideally around the same time each day. Sit upright with your back supported and both feet on the floor. Dont cross your legs. Ideally, before taking a reading, you should keep the cuff on the arm for five minutes without moving or talking.
When you unpack a monitor, you generally have to insert the batteries and connect the cuff to the monitor. If you dont use batteries, youll need an AC adapter only some models come with one .
Avoid pulling on the tube, dropping the monitor, or banging it around. These devices arent fragile, but they are calibrated machines that can get out of whack. Inside each cuff is a bladder that inflates and deflates to take your blood pressure. If the bladder is punctured or doesnt work, you need to replace the cuff. The Velcro holding the cuff together will wear over time, so when it no longer maintains a good hold, you should replace it, even if the bladder is fine. If the cuff is slipping off of your arm, it is not a good fit, said Dr. Veronica Gillispie-Bell, the ob-gyn.
How Long Should You Wait To Take Your Blood Pressure After Working Out
You should wait for at least 30 minutes after working out before taking your blood pressure.
Exercise can temporarily raise your systolic blood pressure. During a workout, your heart needs more oxygen than when at rest, causing you to breathe more rapidly. This causes your heart to pump more blood. Generally, systolic blood pressure elevates to about 160-200 mmHg during exercise, without much change in diastolic blood pressure.
Other factors that affect your blood pressure reading after a workout include:

How Does A Blood Pressure Monitor Work
Digital blood pressure monitors feature a gauge, stethoscope and error indicator in one device. Some cuffs inflate automatically while others require the user to use a pump to inflate the cuff manually, temporarily cutting off blood flow to the arm. The cuff then automatically deflates, allowing blood to flow around the artery in the arm once again. The vibration of this blood flow is detected by the monitor, prompting it to record the systolic blood pressure reading. As it deflates further and these vibrations stop, the monitor records a diastolic blood pressure reading. These blood pressure readings are displayed on the devices screen. Depending on the device, a color indicator may appear to show how the reading compares with normal blood pressure readings.
