The features extracted from PPG waveforms have various clinical applications ranging from blood pressure monitoring to nociception monitoring, while features from ABP waveforms can be used to calculate cardiac output and predict hypertension or hypotension. In recent years, many machine learning models have been proposed to utilize both PPG and ABP waveform features for these healthcare applications. However, the lack of standardized tools for extracting features from these waveforms could potentially affect their clinical effectiveness. In this paper, we propose an automatic signal processing tool for extracting features from ABP and PPG waveforms. Additionally, we generated a PPG feature library from a large perioperative dataset comprising 17,327 patients using the proposed tool. This PPG feature library can be used to explore the potential of these extracted features to develop machine learning models for non-invasive blood pressure estimation.<\/jats:p>","DOI":"10.1101\/2024.03.14.24304307","type":"posted-content","created":{"date-parts":[[2024,3,15]],"date-time":"2024-03-15T18:48:45Z","timestamp":1710528525000},"source":"Crossref","is-referenced-by-count":3,"title":["A signal processing tool for extracting features from arterial blood pressure and photoplethysmography waveforms"],"prefix":"10.64898","author":[{"given":"R.","family":"Pal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Rudas","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.N.","family":"Chiang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Cannesson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"issue":"7","key":"2024031904000954000_2024.03.14.24304307v1.1","doi-asserted-by":"crossref","first-page":"662","DOI":"10.1109\/TBME.2002.1010849","article-title":"A real-time algorithm for the quantification of blood pressure waveforms","volume":"49","year":"2002","journal-title":"IEEE Tran. on Biomedical Engineering"},{"issue":"2","key":"2024031904000954000_2024.03.14.24304307v1.2","doi-asserted-by":"crossref","first-page":"60","DOI":"10.4037\/ccn2002.22.2.60","article-title":"Monitoring arterial blood pressure: What you may not know","volume":"22","year":"2002","journal-title":"Crit.
