Chapter 8: Radical-7
The Radical-7 is a detachable portable noninvasive monitor that measures arterial oxygen
saturation (SpO
2
), pulse rate (PR), and perfusion index (Pi), along with optional
measurements of hemoglobin (SpHb), carboxyhemoglobin (SpCO), total oxygen content
(SpOC), methemoglobin (SpMet), pleth variability index (PVi), and/or acoustic respiration
rate (RRa). It can be docked to Root to transfer parameter data to Root. When Radical-7 is
docked to Root, the device automatically creates a Window that displays all the data from
Radical-7.
Root also acts as a charging station for Radical-7. See Radical-7 Operator's Manual for more
information.
