Masimo SET's sensitivity in detecting true alarms and specificity in rejecting false alarms improves patient time to patient distress. Radical's versatility facilitates standardization of Masimo SET oximetry throughout the department. Radial Handheld easily detaches from the docking station, facilitating both hospital transfer and spotcheck applications. Radical displays SpO2 pulse rate, pleth perfusion index and Signal IQ waveform, or shows the SpO2 and pulse rate as large numbers with pulse indicator.
