The next chapter discusses the blood pressure measurement accuracy and usability of the wearable blood pressure monitor and outlines its product specifications. As the wrist of a subject with an systolic blood pressure of 110 mmHg was gradually compressed, the oscillations of the filtered pulse wave almost completely disappeared after the elapsed time of about 22 seconds. The filtered pulse wave was obtained as an extraction of a pulsation resulting from the relationship between the arterial pressure oscillation and the periarterial pressure from the lower to the systolic blood pressure per pulse stroke. When a pressure slightly higher than the systolic blood pressure of 110 mmHg was applied around the arteries of the subject, the arteries were occluded to stop the oscillations of the filtered pulse wave. The internal pressure of the compression cuff at the elapsed time of 22 seconds was approximately 255 mmHg.
The lowest DBP obtained was 56 mmHg, but this range omission should not have an appreciable effect on the final pass decision. The mean-difference plot for DBP shows limited point variability across the three blood pressure ranges, with strong agreement as one goes below 70 mmHg. Even considering a worst-case measurement difference at or below 50 mmHg, the device would still be able to satisfy all validation criteria to receive a pass result. The Omron HEM-7201 automatic digital blood pressure monitor was able to meet all of the ESH-IP2 validation criteria at 3650 m above sea level in Lhasa, Tibet, passing validation for both SBP and DBP.
If you have specific healthcare concerns or questions about the products displayed, please contact your licensed healthcare professional for advice or answers. omron 3 series monitors all come with a 3 year warranty from date of delivery. If you still have a copy of your receipt or invoice, we can service your monitor free of charge for 3 years from the date of delivery.
At-home blood pressure monitors range significantly in price, largely according to the number of features they offer. Before making a purchase decision, individuals should determine what features they need. For instance, some people might want an electrocardiogram reading function and Bluetooth connectivity. Thus, the intended blood pressure monitor wearable around the wrist all the time just like a wristwatch to take measurements at any time was successfully brought into commercial production. When you use the device with the Omron Connect app , you can see all your blood pressure readings over a given period of time. You can even email the readings to your doctor or show them at your next office visit.
If you desire robust data storage with an easy-to-navigate companion app, we recommend the Microlife Watch BP Home. The pressure that occurs between contractions or beats is where this number comes from. A healthy range is 84 or less; anything above is considered within hypertension range. Find the model that’s best for you to start monitoring your health today.
Without comparing my at-home blood pressure readings to ones taken by a healthcare professional (which aren’t always accurate, either), it’s hard to judge the accuracy of the Omron Platinum Blood Pressure. With all OMRON blood pressure monitors, the recommended time between calibration depends on the use of the product. If the monitor is being used in a home or personal environment, we recommend they are re-calibrated every 2 years.
Few studies have been conducted on blood pressure monitors and their use at high altitude. This study is the first to evaluate an automated blood pressure device at high altitude following a standard validation protocol. The Omron HEM-7201 upper arm automatic blood pressure monitor was tested for accuracy in Lhasa, Tibet, China according to the European Society of Hypertension International Protocol revision 2010 (ESH-IP2). Thirty-three participants received 9–10 sequential blood pressure measurements alternating from a mercury sphygmomanometer and the device. The mean device-observer measurement difference was 1.0 ± 5.9 mmHg for systolic blood pressure and −3.1 ± 4.6 mmHg for diastolic blood pressure . Of the 99 measurement pairs analyzed, 72, 90, and 97 device readings were within 5, 10, and 15 mmHg, respectively, of the observer measurements for SBP, and 68, 92, and 99 readings for DBP.
