Understanding the Sp02 and Pulse Rate Scales.
These scales indicate if your Oxygen Saturation or Pulse Rate levels are considered to be high, low, or normal. The normality levels may vary from person to person. These readings should not be used to treat or diagnose any medical conditions and should not be used to replace medical advice from a licensed physician.
The scales are only visible in the portrait view. When your device is in the landscape orientation the scales disappear.
