The SPD feature qualifies these patterns of desaturation over a period of six (6)
minutes. Depending on the sensitivity setting for SPD, patterns that persist may
result in an SPD alarm, alerting the caregiver to the condition.
Figure 39. Clinically Significant Desaturation Patterns
The SPD feature communicates information to the caregiver about these patterns of
desaturation in a variety of ways.

trend in adults, caregivers are alerted to these patterns via a visual indicator,
and optionally, an audio alarm. The triangle icon for SPD appears on the monitor display
when the feature is enabled. The triangle fills from the bottom to the top as patterns
become more severe. The triangle empties from top to bottom as the patterns become
less severe. If the triangle fills, an alarm sounds. With SPD enabled, the default setting is
On with the sensitivity set to 1. The feature can be turned off in the LIMITS menu.
Caregivers can select from three alarm sensitivity settings: 1 (most sensitive), 2 (medium
sensitivity) or 3 (least sensitive), with 1 resulting in more alarms and 3 resulting in fewer
alarms. The rate at which the SPD icon fills depends on the SPD sensitivity setting.

2. SPD alarms—SPD alarm settings include both audible and visual alarms. Caregivers may
set the alarm type to both audible and visual, or set to visual only.
a. Audible alarm—Once an audible SPD alarm occurs, the oximeter will continue to
alarm for up to six (6) minutes after the alarm triggers or until the caregiver silences
the alarm.
b. Visual alarm—Once an SPD visual alarm occurs, the TREND softkey continues to flash
until the caregiver presses the TREND softkey to review the trend data.
