Frequently Asked Questions:
Can you take SpO2 on your ears?
Masimo lists ear sensors, including the E1, as an alternative monitoring site to digit sensors.1
What is the difference between Nellcor and Masimo SpO2?
Masimo says LNCS sensors are cabled with a DB9 connector, compatible with LNC patient cables, which enables use with Masimo SET pulse oximeters and Nellcor sensor-compatible instruments without OxiMax. Adapter cables are also available for monitors with conventional Nellcor technology. This is Masimo's description of cable compatibility, not a performance comparison.1
