NELLCOR FICTION:

"Nellcor's new forehead sensor is groundbreaking."

FACTS:

• Forehead sensors have been around since the late 1980's, but are not in widespread clinical use due to their unreliability with patients who are supine or in trendelenberg position. In these positions, venous pulsation can make the measurements inaccurate.
• Masimo also has a forehead sensor, and independent studies have shown it to be superior to Nellcor's MaxFast forehead sensor. However, Masimo does not actively promote its use due to the limitation of the forehead as a measurement site.

PROOF:

•  Failure Rates of Transmission and Reflectance Pulse Oximetry for Various Sensor Sites
•  An Evaluation of Forehead Sensors in Intraoperative Surgical Patients
•  Evaluation of 2 Forehead Reflectance Oximeters in Pediatric Intraoperative Surgical Patients
•  Evaluation of Ear Transmission and Forehead Reflectance Oximetry in Intraoperative Surgical Patients
