)
14.1 SpO

Introduction
Pulse Oxygen Saturation (SpO
2
) monitoring is a non-invasive technique used to measure the amount of
oxygenated haemoglobin and pulse rate by measuring the absorption of selected wavelengths of light. The
light generated in the emitter side of the probe is partly absorbed when it passes through the monitored tissue.
The amount of transmitted light is detected in the detector side of the probe. When the pulsative part of the
light signal is examined, the amount of light absorbed by the haemoglobin is measured and the pulse oxygen
saturation can be calculated. This device is calibrated to display functional oxygen saturation.
SpO
2
monitoring is intended for adult, pediatric and neonatal patients.
You can simultaneously measure SpO
2
from two different measurement sources: the MPM module and the SpO
2
module. The measurement from the MPM module is labelled SpO
2
and the measurement from the SpO
2
module
is labelled SpO
2
b.
The following types of SpO
2
can be configured for MPM and SpO
2
modules:
â– Mindray SpO
2
: the connector is blue and no logo is on the module’s front panel.
â– Nellcor SpO
2
: the connector is grey and the logo of Nellcor is on the module’s front panel.
â– Masimo SpO
2
: the connector is purple and the logo of Masimo SET is on the module’s front panel.
