- Low SpO2: If your readings are consistently less than 93%, it indicates low blood oxygen saturation. In such cases, it is recommended to consult a physician immediately.
- Laju pulsa: The pulse rate indicates your heart rate, measured in beats per minute. Normal ranges vary by age and activity level.
Note: Oximeters provide accurate readings, but there may be a variance of 2-4%. Your physician may recommend taking two or three readings to ensure consistency before arriving at a final assessment.
