Monitoring
This chapter explains how to use the pulse oximeter feature of the HP
CodeMaster 100.
SpO
2
monitoring gives information on both cardiac and respiratory systems,
and details of oxygen transportation in the body. It is widely used because it
is non-invasive, continuous, easily applied and painless.
The quality of SpO
2
measurements depends on careful application of the
sensor. Read the following section, to understand the importance of sensor
application. For more detailed information, refer to Understanding Pulse
Oximetry Guide.
You can use the SpO
2
monitor with sensors made by other manufacturers as
well as with Hewlett-Packard sensors. For a list of approved sensors, see the
Sensor Guide.
9Understanding Pulse Oximetry
This section provides a brief description of SpO
2
.
SaO
2
and SpO
2
Hewlett-Packard is adopting the convention of referring to the SpO
2
parameter. Previously it was referred to as SaO
2
.
SaO
2
is the term used to indicate the oxygen saturation of arterial blood.
SpO
2
is the term used to indicate the oxygen saturation of arterial blood as
measured by pulse oximetry.
