SPD feature —Use the OxiMax SPD™ Alert (SPD) feature to detect patterns of desaturation in the
SpO
2
trend in adults. With the SPD feature enabled, the display view includes both the SatSeconds
circle icon and SPD triangle icon and their settings. The SPD alarm sensitivity value appears just
below the SPD icon. When the SPD feature is enabled, the triangle icon fills from the bottom to the
top as desaturation patterns develop. The triangle icon empties from the top to the bottom as
patterns dissipate. If the SPD icon reaches full, it indicates a threshold violation and the SPD alarm
sounds. The oximeter will sound the SPD alarm sooner if the SPD alarm sensitivity is set to the
default value of one (1). A less sensitive setting will result in less frequent alarms. Visible when the
SPD feature is activated and the SPD feature is enabled. For more information about activation,
contact Nellcor’s Technical Services Department at 1.800.635.5267 or your local Nellcor
representative. For more information about using the feature, reference
Using the OxiMax SPD™
Alert Feature , page 54.
When the oximeter is not attached to AC power, it runs on an internal battery. When using the
internal battery, a battery fuel gauge appears in the upper left corner of the display.

Using the Pleth Display
Pleth Display Overview
Use this display view for visual monitoring information in waveform. The
plethysmographic (pleth) display includes a “wiper bar” plethysmographic
waveform, menu bar, and current measured SpO
2
and pulse rate, upper and lower
limit settings. It also includes a battery fuel gauge if running on battery power.
Plethysmographic waveforms with peak to peak amplitudes less than ten pulse
amplitude units (PAUs) are associated. Refer to
Theory of Operations , page 115, for a
description of the pleth waveform. If enabled, SatSeconds and SPD icons display.
•
SatSeconds feature —For mild or brief SpO
2
limit violations, use the SatSeconds feature
to reduce nuisance alarms. With the SatSeconds feature enabled, the SatSeconds circle
icon fills in the clockwise direction as the SatSeconds alarm management system detects
SpO
2
readings outside of the limit setting. The SatSeconds circle icon empties in
counterclockwise direction when SpO
2
readings are within limits. When the icon reaches
full, a medium priority alarm sounds. For more information about using the feature,
reference
Using the SatSeconds™ Alarm Management Feature , page 58.
