Question

Can pregnant women not measure their blood pressure with a Samsung health monitor? Why is that?  

Answer

In the case of pregnant women, there is a prior study that the blood pressure measurement using a commercial cuff type blood pressure meter is less accurate. Therefore, when calibrating with a cuff type blood pressure meter with low accuracy, the results of output from the Samsung Health Monitor app will also not be accurate. Also, there is a big hormonal change during pregnancy, so blood vessel characteristics are different from ordinary people. Our blood pressure measurement method uses PPG signals that are affected by blood vessel characteristics, and the current algorithm does not reflect the effects of changes in blood vessel characteristics caused by hormonal changes during pregnancy, thus limiting the measurement of pregnant women.
