Improving pulse oximetry accuracy in dark-skinned patients: technical aspects and current regulations. Br J Anaesth. 2023 Oct;131(4):640-644. doi: 10.1016/j.bja.2023.07.005.0007-091210.1016/j.bja.2023.07.005https://hdl.handle.net/20.500.14352/117298Recent concerns regarding the clinical accuracy of pulse oximetry in dark-skinned patients, specifically in detecting occult hypoxaemia, have motivated research on this topic and recently reported in this journal. We provide an overview of the technical aspects of the issue, the sources of inaccuracy, and the current regulations and limitations. These insights offer perspectives on how pulse oximetry can be improved to address these potential limitations.engjournal article1471-6771https://doi.org/10.1016/j.bja.2023.07.005https://www.sciencedirect.com/science/article/pii/S0007091223003781?via%3Dihubhttps://pubmed.ncbi.nlm.nih.gov/37544838/restricted access617-089.5Clinical accuracyDark skinHypoxaemiaMelaninPulse oximetryRegulationsAnestesiología y reanimación2411.02 Anestesiología
