The Masimo Carboxyhemoglobin Saturation (SpCO) Parameter Upgrade (#2296) is an upgrade which can be ordered to enable SpCO measurements on the Radical-7 Pulse Oximeter (#9500), Rad-57 Pulse CO-Oximeter, Rad-87 Pulse Oximeter, or Root Patient Monitor.

The SpCO Parameter provides continuous and noninvasive measurement of the carbon monoxide levels in arterial blood, thus allowing for detection of carbon monoxide (CO) poisoning.
