The aim of this project is to test the reliability of automatic oscillometric blood pressure measurements by implementing a real-time application in C++. The application automatically measures the user's pulse and blood pressure by using a manual blood pressure cuff equipped with a pressure sensor that is connected to a USB-DUX-SIGMA converter, connected to a Linux computer.

If there is no USB-DUX devide connected to the computer, the application will not start up. If the USBDUX-D device is used, a warning will be written into the programs log file, but the application will still run. The USBDUX-D device has only 12-bit instead of 24, like the SIGMA device, which is not enough for the blood pressure detection to work.
