Arterial blood pressure cannot be measured with precision by means of sphygmomanometers. The method is attended by inaccuracies caused by variations in heart rhythm, the presence of normal respiration, and resistance of the tissues of the part. (1) this preliminary design specification describes a concept for the design and fabrication of a semi-automatic blood pressure device. This device translates brachial arterial fluid motion through a fluidic detector, which will determine systolic, diastolic pressures. Additionally, this device is intended for use in emergency situations, i.e. emergency equipment, army field use, air evacuation equipment and combat conditions.
