H.15C Hypoxemia alert: Detecting oxygen drops with a color-changing ring in high-risk patients

Many patients with lung/heart disease experience episodes where their oxygen levels drop due to acute exacerbation of their disease. Patients rarely know that their oxygen levels are dropping until they start feeling very short of breath and need to be hospitalized urgently. This has also been happening very frequently in patients with COVID-19. The goal of this project is to develop a device for use at home or out-of-hospital settings that detects oxygen levels in the blood and indicates to the user and their appropriate healthcare provider when oxygen levels start to drop. This device can be worn by patients with covid, patients with lung disease, or patients with heart disease so it can warn them when their oxygen levels are dropping early enough to seek medical care before things decompensate further.
