Why Masimo Medical Equipment is not reading SpO values correctly?
- RRodney LawrenceAug 29, 2025
If the SpO values from your Masimo Medical Equipment do not correlate with clinical assessments or ABGs, it could be due to low perfusion or sensor displacement. Check for any error messages. Also, check the sensor placement and ensure it's not too tight. You may need to reapply the sensor or select a new site. Setting the device to MAX sensitivity can also help, and always confirm the sensor is securely attached to the patient. Refer to the sensor's Directions For Use.
