  "abstract": "The covid-19 pandemic exposed three longstanding problems with pulse oximetry. Firstly, pulse oximeters can produce inaccurate readings in some patients.12 Secondly, even small levels of inaccuracy can harm patients when clinicians follow guidelines in which critical clinical decisions are based on an absolute or narrow range of oxygen saturation values.3 Thirdly, many clinicians are unaware of the potential for pulse oximeters to produce inaccurate readings and the factors that can cause this (including patients with darker skin tones), as well as the importance of interpreting and evaluating oxygen saturation readings in their clinical context and with an understanding of the limitations and imperfections of pulse oximetry.1456",
