A Prototype for Automatically Blood Pressure Measurement with Wireless Communication to a Graphical User Interface in MATLAB

High blood pressure and its pathologies are among the main diseases suffered by Mexicans. Many people may consider themselves prone by inheritance or lifestyle, so monitoring this biometry could help for early diagnosis. As part of the treatment, hypertensive people must keep a record that the doctor can consult periodically about the behavior of the patient blood pressure. In this work, a prototype that automatically takes blood pressure and communicates the data to a PC through a graphical user interface (GUI) in MATLAB is proposed. The values of systolic and diastolic pressures set from the prototype were compared against measurements using a digital wrist baumanometer, obtaining a percentage error less than 4%. Therefore, it can be concluded that the prototype gives not only precise, but also exact values of blood pressure.
