why most smartwatches cannot measure blood pressure

Answer: The majority of smartwatches are not designed to measure blood pressure, and this is for a variety of reasons. Firstly, the sensors that are used to measure blood pressure require special calibration in order to produce accurate readings. Secondly, testing devices can be expensive and may not be practical for widespread use.

Thirdly, the accuracy of these readings can suffer if the watch is worn improperly or if there is another obstruction between the sensor and the skin surface.
Therefore, while it would be desirable to have a wristwatch that could measure blood pressure effectively and cheaply, at present this remains an elusive goal.

does a smartwatch measure blood pressure accurately?

Answer: Yes, most modern smart watches measure blood pressure accurately. This is done by measuring the amount of oxygen that is delivered to your wrist through a small probe that’s inserted under the skin. The watch then calculates your blood pressure based on this data.

how do smartwatches measure blood pressure?

Answer: Blood pressure monitoring with a smartwatch can be done in two ways. The first is by using the built-in sensors to measure your blood pressure and then transmitting this information wirelessly to the watch. This works well for people who have mild hypertension or are otherwise healthy and do not expect their BP readings to change significantly from day to day.
The second way is by having an external device that connects directly to your watch via Bluetooth or Wi-Fi and then downloading special apps that allow you to monitor your blood pressure on the go. These devices tend to be more accurate, but they are also more expensive than those that use internal sensors alone.

Do Smartwatches measure blood pressure correctly?

Answer: Some smartwatches are capable of measuring blood pressure, but it is important to note that these devices are not perfect. In fact, they may give inaccurate readings due to incorrect placement of the cuff or variability in your BP throughout the day. Additionally, some people have reported that their watches recorded abnormally high blood pressure even when their actual BP was normal. Therefore, if you’re interested in monitoring your blood pressure using a smartwatch, be sure to speak with your doctor first about whether this is a suitable option for you. And if you do decide to use a wearable monitor for hypertension management, make sure that you select one that offers accurate and consistent measurements across multiple time points and environments.
