Abstract
A photoplethysmography (PPG) circuit obtains PPG signals at a plurality of wavelengths of light reflected from tissue of a user. A processing device generates parameters using the PPG signals to screen the user for an infection, such as sepsis, influenza and/or COVID-19. The processing device may also determine a severity level of the infection and a confidence level in the determination. The parameters may include a measurement of nitric oxide (NO) level, respiration rate, heart rate and/or oxygen saturation.
