General Description for SpOC
The above approximations result in the following reduced equation for oxygen content via
the Pulse CO-Oximeter:
SpOC (ml/dL*) = 1.31 (ml O2/g Hb) x SpHb (g/dL) x SpO2 + 0.3 ml/dL
*When ml O2/g Hb is multiplied by g/dL of SpHb, the gram unit in the denominator of ml/g
cancels the gram unit in the numerator of g/dL resulting in ml/dL (ml of oxygen in one dL of
blood) as the unit of measure for SpOC. See Safety Information, Warnings, and Cautions on
page 11.
General Description for Carboxyhemoglobin (SpCO)
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of
carboxyhemoglobin concentration (SpCO) in arterial blood. It relies on the same basic
principles of pulse oximetry (spectrophotometry) to make its SpCO measurement.
The measurement is obtained by placing a sensor on a patient, usually on the fingertip for
adults and the hand or foot for infants. The sensor connects either directly to the Pulse
CO-Oximetry instrument or through an instrument patient cable.
The sensor collects signal data from the patient and sends it to the instrument. The
instrument displays the calculated data as percentage value for the SpCO, which reflect
blood levels of carbon monoxide bound to hemoglobin.
Successful Monitoring for SpCO
A stable SpCO reading is associated with correct sensor placement, small physiological
changes during the measurement and acceptable levels of arterial perfusion in the patient’s
fingertip (measurement site). Physiological changes at the measurement site are mainly
caused by fluctuations in the oxygen saturation, blood concentration and perfusion.
General Description for Methemoglobin (SpMet)
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the levels of
methemoglobin concentration (SpMet) in arterial blood. It relies on the same basic
principles of pulse oximetry (spectrophotometry) to make its SpMet measurement.
The measurement is obtained by placing a sensor on a patient, usually on the fingertip for
adults and the hand or foot for infants. The sensor connects either directly to the Pulse
CO-Oximetry instrument or through a patient cable.
The sensor collects signal data from the patient and sends it to the instrument. The
instrument displays the calculated data as percentage value for the SpMet.
