Humans must keep their bodies' levels of oxygen in balance to stay healthy. Hypoxia, which is common in respiratory illnesses such as pneumonia, the flu, and COVID-19, is a state in which there is insufficient oxygen in the tissues to maintain appropriate homeostasis. Using a customized multimodal biosensor device, the aim of this observational study is to develop a point-of-care method for screening and monitoring individuals with infectious respiratory diseases.
