Medtronic Nellcor SpO2 Application Manual
APPLICATION GUIDE
For Nellcor™ Forehead SpO2 Sensor
with OxiMax™ Technology
To ensure reliable, accurate pulse oximetry
readings from Nellcor™ forehead SpO2
sensors, always remember to:
Think PIRATE
1
(Place It Right Above The Eye)
Prepare t he site with alcohol
∙
Remove the adhesive backing strip
∙
Always use the NellcorTM forehead
2
SpO2 headband positioned over the
sensor and adjust the tension to align
green arrows with indicator
Alternate the sensor site from above
3
one eye to the other every 12 hours
Prepare t he site with alcohol
∙
Change the adhesive layer
∙
when ne cessary
Reapply the headband
∙
Because individual skin condition aff ects the
ability of the skin to tolerate sensor placement,
with some patients it may be necessary to
change the sensor site more frequently.
The Nellcor™ OxiMax™ forehead SpO2 sensor
is more closely aligned to arterial blood gas
(ABG) draws than digit sensors.
*1-3
Forehead sensors detect
hypoxemic events faster
than other sensors
The forehead of a healthy adult
∙
expose d to cold tempera tures stays
warm while the ngers, ears and
nose lose h eat (Figure 1)
Cold causes vasoconstriction and
∙
low peripheral perfusion
Forehead SpO2 measurements are
∙
more accurate than nger SpO2
measurements in critically ill patients

Do not use digit
sensors on a patient’s
head or ears
When used on foreheads,
digit sensors give inaccurate,
often overestimated SpO
levels (Graph 1)
