Blood pressure measurement values vary from the left arm to the right arm. The average is generally within 10 mmHg for most individuals. Omron home blood pressure monitors are generally designed for use on the left arm as they are validated through clinical studies using the left arm. You should talk to your doctor before using the right arm to take a measurement.

Verdict

No specific evidence is yet available on the use of wrist BP machines or home BP monitoring in patients with COVID-19 or other acute respiratory illness. Wrist blood pressure machines are accurate to within -2.5 to 3.5mmHg of upper arm BP machines, and achieve correct BP classification in over 80% of people compared to ambulatory BP monitoring.

Background

Based on initial reports from China, and subsequent evidence that hypertension may be associated with increased risk of mortality in hospitalized COVID-19 infected subjects, there have been questions about the role of home BP monitoring in people with hypertension who need to self-isolate. Especially the accuracy and reliability of wrist BP machines sold in pharmacies.

Summary of findings from the most useful papers.

The only clinical trial-specific to wrist BP devices found the categorization of subjects as normotensive or hypertensive, using the wrist device in subjects without specific training, achieved a correct classification in 84% of cases with a position sensor in comparison to ambulatory BP monitoring .

Want Your True Blood Pressure Avoid Wrist Monitors Experts Say

The researchers, who published their findings in the August issue of the Journal of Hypertension, say that the Klock wrist monitor “cannot compete” with the accuracy of the conventional method of taking blood pressure in the doctor’s office. Doctors use a blood pressure monitor that wraps around the upper arm so that the user can listen for changes in the sound of the pulse, found in the bend of the arm.

The researchers tested the Klock wrist device against standard blood pressure monitors on 255 patients, aged 18 to 95. They found that systolic blood pressures — the top number in a blood pressure reading — measured with the conventional monitor were 16 points lower, and that diastolic pressures — the bottom number — were lower by seven points than the readings obtained by the wrist device. In addition, the wrist monitors overestimated the higher systolic and diastolic pressures, and underestimated lower diastolic blood pressures.

The differences are noteworthy, say researchers, because many people use these monitors at home, and because doctors prescribe or change medication based on these blood pressure readings. If readings are off by 10 to 20 points, it could mean that patients receive incorrect doses of medication.

One major problem with the study, the researchers note, is that they only tested one brand of wrist monitor, and the results may not apply to other brands, but doctors aren’t convinced that any of the wrist monitors are accurate.

Historically Why Wrist Blood Pressure Monitors Were Less Accurate

Wrist monitors are more prone to errors if directions are not followed properly. The main reason: The arteries around the arm is thick and resides deep in the forearm, allowing the monitor to measure blood pressure accurately. In contrast to an upper arm, the wrist arteries are thin and not deep in the skin thus hinder the process of blood pressure.

Is Wrist Blood Pressure Monitors More Accurate Than Upper Arm Blood Pressure Monitors

Traditionally, upper arm blood pressure monitors have been the preferred device for clinics, hospitals, and doctors offices. However, recent studies have shown that wrist blood pressure monitors may provide a more accurate reading of the information that needs to be taken. This is because wrist monitors measure pressure at the artery near the hand, which might be more accurate. After all, it is physically closer to the heart. Upper arm monitors measure pressure at the artery near the shoulder, an inch or two from the heart.

When doing this type of a comparison, it is very important that the measurements are taken in a certain manner in order for the reading on the Omron monitor to be accurate. The Omron monitor uses oscillometric technology that measures the vibration of the blood as it moves through the arteries. The doctor is using a different method of measurement and listens to the sound of your heart. It is necessary for the doctor to take the first measurement using the Omron monitor. The brachial artery is fully open and not restricted so vibration of the blood is accurately measured. It is also important to note that the different test methods may give slightly different readings due to the test methods or due to the normal fluctuation in blood pressure.

A Common Mistake Affecting The Accuracy Of Wrist Cuffs

Regardless of what kind of blood pressure monitor youre using, there are certain guidelines which must be followed to achieve an accurate reading. The #1 mistake people are doing goes for all monitors but is committed more when people are using a wrist monitor.

The mistake is in regards to the height of the blood pressure cuff at the time of measurement.

To get an accurate blood pressure reading with a wrist monitor, the cuff must be at the same level as the heart. Blood pressure measured below or above the heart will reflect hydrostatic pressure. Hydrostatic pressure in the blood vessels is caused by the weight of the blood above it in the vessels 5.

It will be lower above the heart where blood has been pushed up against gravity. It will be higher below the heart where the weight of the blood above the measurement point will add to the pressure contributed by the heart.

Having the cuff at heart level is more difficult to achieve when using a wrist monitor. In addition, many people make the mistake of holding their wrist down on their leg or on the arm of the chair. The result is the cuff lower than the heart and an inaccurate measurement.

How To Use A Wrist Blood Pressure Monitor

Despite a wrist blood pressure monitors flaws, Dr. Avetian says its not a bad idea to have one at home, especially if youre a senior with a condition like hypertension . The public can get a better idea of their blood pressure range, and if there are any elevation or concerns, they can then contact their provider, he says.

If you opt for a wrist blood pressure monitor, positioning is extremely important. You need to position the monitor directly over the wrist pulse to get an accurate reading, says Dr. Kroll. Keep your wrist at heart level, supported on a table or other surfaceDr. Feda notes that holding your arm in midair can lead to a higher reading.

Dr. Feda also recommends the following before a reading:

• Wait 30 minutes after exercising, smoking, eating a salt-heavy meal or drinking anything with caffeine. These activities can temporarily increase blood pressure.
• Make sure you feel relaxed and sit in a relaxed position for five minutes.
• Sit with both feet on the ground and your back supported.
• Avoid speaking, checking social media or answering text messagesbasically anything that could lead to stress and a higher reading.
• Empty your bladder.

Feel free to take several readings, too. Often, the initial reading is higher than subsequent ones, so patients should wait at least one minute and then re-check it, says Dr. Feda.
