Performance Inconsistency of Pulse Oximeters Over Five Years of Clinical Use: A Single-Center Study of Masimo Devices - PubMed
The accuracy of the tested medical-grade pulse oximeter changed year-to-year at a large hospital compared to concurrent arterial blood gas saturation, potentially complicating safe clinical decision-making and application of evidence-based medicine. Errors of false hypoxemia became more common, thre …

There’s been some “advice” coming from some quarters for scientists not to focus on DEI-related funding cuts. I wholly reject this concept. Cutting programs designed to reduce science and healthcare disparities is as detrimental to science as anything else, both morally and functionally.
