NELLCOR FICTION:

"Nellcor uses a cardiac-based algorithm, while Masimo uses a saturation-based algorithm to determine oxygen saturation and pulse rate."

FACTS:

• There is no such thing as a cardiac-based pulse oximetry algorithm, since pulse oximetry, by definition, analyzes pulses via plethysmographic waveforms (pleth) derived from peripheral vascular measurements. Nellcor's own description of their "cardiac cycle" based method states clearly that they are using pulse waveforms to make their calculations.
• Masimo's patented parallel engines use multiple algorithms—including both pulse- and saturation-based algorithms—to provide the world's most accurate SpO₂ and pulse rate. In contrast, Nellcor only uses pulse based algorithms.

PROOF:

•  Masimo SET Pulse Oximetry Algorithms
