Can Smartwatch Measure Blood Pressure?
Dec 20, 2023
Fitness trackers are sensitive to blood pressure and can be measured on the wrist. The wrist must measure blood pressure at heart level to be more accurate. Measurements on the arm may also be inaccurate or higher than measurements on the wrist. This is possible because the arteries in the wrist are smaller and shallower. That's how a fitness band measures blood pressure.
Most fitness trackers use an oscilloscope in the morning and evening. Electronic sensors automatically measure blood pressure. So the cuff of the smartwatch will inflate automatically. This Narrows blood vessels and stops blood flow.
In order for the blood to flow, the pressure has to be released slowly. Pressure sensors will detect pulsations and oscillations in the arteries. The maximum value was recorded and used to calculate systolic or diastolic blood pressure. This is the method of calculating blood pressure with oscilloscope.
Another technique for accurate blood pressure measurement is PPG. This is a heart rate sensor that uses a pulse oximeter. Light absorption occurs when a sensor illuminates the skin.
They don't use any inflatable cuff technology, which makes them less accurate than sphygmomanometers. If you follow the user guide, you can still get the best results.
