Monitoring SpO2, SpCO, and SpMet
SpO
2
, SpCO™, and SpMet™ are optional features for the LIFEPAK 15 monitor/defibrillator.
When all three options (SpO
2
, SpCO, and SpMet) are installed, the pulse oximeter measures
functional oxygen saturation (SpO
2
), carboxyhemoglobin concentration (SpCO), and
methemoglobin concentration (SpMet) in the blood.
IMPORTANT! SpO
2
-only sensors and combination SpO
2
, SpCO, and SpMet sensors are
available for use. Masimo
®
SpO
2
-only sensors that have a red connector are compatible with the
LIFEPAK 15 monitor. Masimo Rainbow
®
sensors are necessary to monitor SpCO and SpMet in
addition to SpO
2
. These sensors are not compatible with other LIFEPAK defibrillator/monitors.
Nellcor SpO
2
sensors may be used with the LIFEPAK 15 monitor/defibrillator, if the Masimo
Red™ MNC adapter cable is used.
For a list of SpO
2
sensors and connector cables that are intended for use with the
LIFEPAK 15 monitor/defibrillator, see the Physio-Control website. Carefully read the Directions
for Use that are provided with the sensors and connector cables for a complete description,
instructions, warnings, cautions, and specifications. To order sensors and connector cables,
contact your Physio-Control representative. In the USA, call Customer Support at

Intended Use
A pulse oximeter is a noninvasive device that continuously measures functional oxygen
saturations (SpO
2
), carboxyhemoglobin concentration (SpCO), and methemoglobin
concentration (SpMet) in the blood. Continuously monitoring SpO
2
can provide an early warning
when oxygen saturation is decreasing and can help the clinician act rapidly before the patient
develops the later signs of hypoxemia. Previously, the blood parameters SpCO and SpMet could
only be obtained from invasive blood gas samples. This new technology assists in identifying the
