Why the study?
The study was conducted to improve the sampling rate and cost efficiency of a blood pressure recording unit compared to a previous recorder using Arduino and PLX-DAQ.
Answers are grounded in this paper and cite their sources.
A low-cost blood pressure recording unit was developed using NI-myDAQ and LabVIEW, achieving a high sampling rate compliant with ISO standards.
This paper discusses the improvement of blood pressure recording unit in sampling rate and cost efficiency from the previous recorder using Arduino and PLX-DAQ. In order to increase the sampling rate, the NI-myDAQ device and LabVIEW program were used. The recording unit was able to record the blood pressure samples with the sampling rate 200000 samples/second which complies with the ISO/TS 81060-5 : 2019 with relatively low-cost. However, further development in recording Korotkoff sounds, determining systolic, diastolic, and mean arterial blood pressures are required.
