To obtain SpO
2
measurements and SpO
2
Heart Rate from the Accutorr V with an optional
SpO
2
module, see: section 3.11.2 for units with Nellcor SpO
2
, section 3.11.3 for units with
Masimo SpO
2
, and section 3.11.4 for units with DPM SpO
2
.
The LCD Display (17) can display a normalized PLETH waveform from SpO
2
data. To view
the waveform when the LCD shows any other display, press the DISPLAY key (11).
CAUTION:
NOTE:
If a reading cannot be obtained, or the reading is
inaccurate, check the patients vital signs by alternate means
and consider the following:
•
If the patient is poorly perfused, try applying the sensor to another
site (i.e., a different finger or toe).
•
Check that the sensor is properly aligned.
•
In electrosurgery, verify the sensor is not too close to ESU devices or
cables.
•
Verify the site area is clean / non-greasy. Clean the site and sensor if
needed. Remove nail polish and fungus.
NOTE:
The pulse tone frequency increases as oxygen saturation
increases.
NOTE:
SpO
2
modules on the Accutorr V have a typical response
time of 15 seconds.
NOTE:
Information specific to the technical design of Nellcor and
Masimo SpO
2
modules should be obtained from the
manufacturer.

Sensor Selection and Application
Selection of a specific sensor is based on the patient’s size, physical condition, and expected
monitoring duration. Sensor application instructions are provided in each sensor package.
For optimal placement, ensure that the cable side is placed in the correct position (see
FIGURE 3-15 and FIGURE 3-16).
