• 16:10, 13 December 2024 CwoodahlS talk contribs created page Digital Twin for Imaging Skin (Created page with "==Introduction== Blood oxygen saturation is an important health indicator. When blood oxygen levels drop below a certain threshold, extremely dangerous, even life-threatening, conditions can occur due to the lack of oxygen reaching vital organs. Platforms to monitor blood oxygen saturation have therefore been a sought-after solution, as seen in the development of pulse oximeter finger monitors and the addition of monitors onto smartwatches, such as the Apple Watch.
