Pulse Oximetry Monitors go beyond conventional SpO2
The leader in this market is Masimo with their SET platform. 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 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.
