SPD
trend data—The trend history captures the SPD patterns and defines periods when
the SatSeconds and SPD alarms were activated. Once patterns exceed the SPD limit, the
TREND menu option will flash. Caregivers should view the data to examine SatSeconds
and SPD patterns in the trend data history. To change the amount of time visible in the
trend view, press the TIME softkey to change time scale.

SPD Trend Data, 15 minute
When the indicator reaches capacity, indicating the SPD limit has been reached, an
audible alarm sounds and the TREND softkey flashes. The TREND softkey continues
to flash until the caregiver presses the TREND softkey to review the trend data. The
default setting of one (1) is the most sensitive to desaturation patterns and results in
more frequent alarms. For less frequent alarms, use a less sensitive setting of two (2)
or three (3).
To set the OxiMax SPD™ Alert (SPD) sensitivity
WARNING
Supplemental oxygen will attenuate patterns of desaturation. A patient’s respiratory
compromise can be proportionally more severe before patterns appear in the
saturation trend. Remain vigilant when monitoring a patient on supplemental oxygen.
WARNING
The SPD feature is for use with adults patients only. In Neonate Mode, the SPD feature
remains OFF.
The SPD sensitivity setting establishes a threshold for how sensitive the oximeter is
to patterns of desaturation. The default setting of one (1) is the most sensitive.
Note:
When SPD is enabled, the SatSeconds feature is automatically enabled with a setting of 100.
Note:
The ability to adjust the alarm limit default settings can be enabled or disabled by qualified
service personnel as described in the
N-600x Service Manual
.
Note:
Prior to changing SPD sensitivity settings, clear all alarms.
With the oximeter in the normal monitoring mode, press the LIMITS softkey. The
current alarm limits display.
