Content: The recording frequency for pulse ox data will depend on the settings of your watch and can vary from model to model. There are three modes to choose from. Spot Check Mode
Spot Check Mode is enabled when you scroll to the Pulse Ox widget on the watch and is used for getting your current SpO2 level. The watch will take a sample reading at that time. It will not take any other further readings until you navigate back to the Pulse Ox widget on your watch. Refer to "Getting Pulse Oximeter Readings" in your owner's manual for detailed steps on how to access the Pulse Ox widget. All-Day Mode
In All-Day Mode the watch will sample your SpO2 levels every 5-15 minutes. If the watch detects a high level of movement (e.g. out for a run) it will read less often. When viewing Pulse Ox on the watch, you will see the average of readings for each hour. NOTE:
