General Description for SpOC
The above approximations result in the following reduced equation for oxygen
content via the Pulse CO-Oximeter:

/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.

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.

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 Total Hemoglobin (SpHb)
Pulse CO-Oximetry is a continuous and noninvasive method of measuring the
levels of total hemoglobin (SpHb) in arterial blood. It relies on the same principles
of pulse oximetry to make its SpHb measurement. The measurement is taken by
a sensor capable of measuring SpHb, usually on the fingertip for adult and
pediatric patients.
