Abstract: Methods, systems, and devices for blood oxygen measurement are described. A method may include receiving, via a wearable device, a first photoplethysmogram (PPG) signal for a user acquired during a time interval using a first set of PPG sensors, and receiving a second PPG signal for the user acquired during the time interval using a second set of PPG sensors that are different from the first set of PPG sensors. The method may include comparing the first PPG signal and the second PPG signal, and determining one or more blood oxygen saturation metrics for the user during the time interval based on the comparison of the first PPG signal and the second PPG signal. The method may include causing a graphical user interface (GUI) to display an indication of the one or more blood oxygen saturation metrics.
