PhysBP to monitor arterial oscillations during oscillometric blood pressure measurement
Description
Cardiovascular diseases are a leading cause of global deaths and this makes it critical to be monitored. Blood pressure is one of the crucial health parameters in cardiovascular health monitoring. Automatic sphygmomanometers based on oscillometric measurement are commonly used to measure blood pressure. For the end user, these devices inform about the systolic and diastolic pressures while keeping the oscillometric signal and algorithm hidden. Hence, such devices can not be directly used in research for analysing arterial oscillations that rise in an occluded artery placed inside a pressurized cuff. No doubt some commercial devices are available that provide access to the oscillometric signal. This note presents a low-cost device equipped with two pressure sensors, active filtering, data logger and an interactive user interface that not only provides real time oscillometric signal but also enables for real time signal processing and saving the data for analysis. Data processing can give one insights such as mean arterial pressure, systolic blood pressure, diastolic blood pressure and shape index of the oscillometric envelope. Researchers can also use this device, that we call PhysBP, to implement and quantify different algorithms being used to estimate the systolic and diastolic pressures. It is low cost, equipped with readily available off-the-shelf components and easy to reconstruct. This dataset contains design files such as CAD files for mechanical fabrication and 3D printing, circuit schematics, gerber and placement files for PCB fabrication.
