    What makes Masimo SET different than other (conventional) pulse oximetry? - Dec 1, 2009

    Conventional pulse oximetry assumes that arterial blood is the only blood moving (pulsating) in the measurement site. During patient motion, the venous blood also moves, which causes conventional pulse oximetry to under-read because it cannot distinguish between the arterial and venous blood. Masimo SET (Singnal Extraction Technology) signal processing identifies the venous blood signal, isolates it, and using adaptive filters, cancels the noise and extracts the arterial signal. It then reports the true arterial oxygen saturation and pulse rate.

    Conventional Pulse Oximetry provides inaccurate monitoring or signal dropout during:

    • Patient Motion or Movement
    • Low Perfusion (low signal amplitude)
    • Intense Ambient Light (lighting or sunlight)
    • Electrosurgical Instrument Interference

    Masimo SET pulse oximetry works accurately where conventional pulse oximetry tends to fail. More than 100 independent and objective peer-reviewed clinical studies published and presented in internationally respected forums and numerous additional studies in progress document the significantly superior performance of Masimo SET Pulse Oximetry. The technical innovations that are the basis of the Masimo SET Pulse Oximetry system and Masimo LNOP® SpO2 sensors are addressed by approximately 200 patents issued and pending in the United States and other key countries.

    Masimo Rainbow SET Measurements:

    • Hemoglobin (SpHbT)
    • Oxygen Content (SpOCT)
    • Carboxyhemoglobin (SpCO®)
    • Methemoglobin (SpMet®) Pleth Variability Index
    • PVIT ( Pleth Variability Index)
    • Plus: Masimo SET measurements of Oxygen Saturation (SpO2), Pulse Rate (PR), Perfusion Index (PI)

    Based on the solid foundation of Masimo SET technology:

    • Innovative noninvasive sensor technology uses more than 7 wavelengths of light to acquire blood constituent data based on light absorption
    • Advanced signal processing algorithms and unique adaptive filters work together to isolate, identify and quantify various hemoglobin species
    • Blood measurement results are then displayed numerically

    NB: The Masimo Radical 7 & Radical 5 demonstration models are available at the Mednet -Healthcare head quarters in Ndeeba.
