The question is, “How accurate are fitness trackers for blood pressure?” or how do fitness bands measure blood pressure. Fitness trackers and smart bands come with many options nowadays. They can calculate the number of calories burned, steps count, and many more. These fitness trackers can also measure the blood pressure of an individual. Wearing a BP monitor helps you to get a clear picture of heart health and detect heart problems.
Fitness trackers are good at measuring heart rate when in rest or recovery, but as the intensity of the workout increases, the fitness band accuracy decreases. The American Heart Association recommends that people with high blood pressure should check their blood pressure using a sphygmomanometer. The post will show that How accurate are fitness trackers for blood pressure?
The fitness trackers measure blood pressure at the wrist and this makes them extremely sensitive. In order to make this effective, the blood pressure is to be measured when the wrist is at the heart level so the readings could be accurate. Also, the measurement could be higher or inaccurate from the one taken at the arm. This is because the arteries at the wrist are narrower and not deep. This will explain How do fitness bands measure blood pressure?
Most of the fitness tracker uses the oscillometric in morning and evening. This system measures the blood pressure automatically using an electronic sensor. The cuff of the smartwatch is inflated automatically as a result arteries become narrow and blood doesn’t flow through them. The pressure is then released slowly to allow blood to pass. As the pressure sensor detects arterial pulsations as oscillations. And when it reaches the maximum value is noted down which is used to calculate systolic and diastolic pressure. This is how blood pressure is calculated using the oscillometric technique.
The other technique that is used to measure blood pressure accuracy is PPG. It is a heart rate sensor that uses a pulse oximeter. This works on the principle of light absorption when the sensor illuminates the skin. However, they don’t have any inflatable cuffs technology that makes them less accurate than the sphygmomanometer. However, if user guidelines are followed properly then you can get the best results from it.
