Hi @MJaha.1 ,
the typical range for ST pressure sensors is 260 to 1260 hPa. A typical blood pressure for a healthy man ranges from 40 mmHg (53 hPa) to 180 mmHg (240 hPa): for this reason, considering 1000 hPa as "atmospheric pressure offset" at sea level, you should be able to cover the required range with all ST portfolio devices.
A different issue is related to the implementation of the measurement setup: you have to be able to put in contact the blood pressure with the MEMS pressure sensor. If you use a "sphygmomanometer" setup (in some flavor), I would suggest you to use a barometer with a water resistant package (you can find here a product selector for choosing the most suitable device for your application).
Which is, more in detail, your target application?
