Ss. Cyril and Methodius University Researcher Has Provided New Study Findings on Biomedical Engineering [Critical Oxygen Saturation-level Estimation From Photoplethysmogram (Ppg): A Prisma-compliant Systematic Review And Meta-analysis].

Researchers at Ss. Cyril and Methodius University conducted a meta-analysis on the use of Photoplethysmogram (PPG) signals to estimate critical oxygen saturation levels (<90%). The study found that only 21 out of 75 papers considered these critical levels, highlighting issues such as limited data availability, undisclosed methodologies, and lack of reproducibility in some studies. The research provides valuable insights for improving SpO2 estimation and calculation using PPG signals, offering concrete guidelines for future researchers and developers in the field of biomedical engineering. The study was funded by the North Atlantic Treaty Organization and published in the journal Biomedical Engineering: Applications, Basis and Communications. [Extracted from the article]
