Presentation of the literature search and selection procedure together with the numbers of records at each stage sourced from PubMed from 1 January 2012 to 1 January 2022 using the following keywords: ((“critical care”[MeSH Terms] OR (“critical”[All Fields] AND “care”[All Fields]) OR “critical care”[All Fields] OR (“oximetry”[MeSH Terms] OR “oximetry”[All Fields] OR (“oxygen”[All Fields] AND “saturation”[All Fields]) OR “oxygen saturation”[All Fields]) OR (“oximetry”[MeSH Terms] OR “oximetry”[All Fields] OR (“o2”[All Fields] AND “saturation”[All Fields]) OR “o2 saturation”[All Fields]) OR “PPG”[All Fields] OR (“photoplethysmogram”[All Fields] OR “photoplethysmograms”[All Fields]) OR (“photoplethysmography”[MeSH Terms] OR “photoplethysmography”[All Fields])) AND ((“publicly”[All Fields] AND (“availabilities”[All Fields] OR “availability”[All Fields] OR “available”[All Fields])) OR (“freely”[All Fields] AND (“access”[All Fields] OR “accessed”[All Fields] OR “accesses”[All Fields] OR “accessibilities”[All Fields] OR “accessibility”[All Fields] OR “accessible”[All Fields] OR “accessing”[All Fields])))) AND ((humans[Filter]) AND (english[Filter])). Papers that met the inclusion criteria, discussing the development and publication of original pulse oximetry datasets, were selected for analysis. This resulted in 12 research papers representing 12 publicly available datasets. Here n refers to the number of studies, where m refers to the number of publicly available databases.
