Managing the Data Port
Caution
Signal artifacts, secondary to a variety of external factors may compromise the presence or
accuracy of the displayed oximeter values.
Additional Data Fields with SPD feature enabled
The SPD feature adds two fields to the column heading and an extra column to the
far right of the displayed data or print-out (not provided in real-time output) when
using the default ASCII protocol.
1. Pulse Rate (PR) Alarm Delay Limit—The oximeter monitors the pulse rate and
sounds an alarm if the pulse rate exceeds or drops below expected limits. A higher
pulse rate alarm delay threshold allows for momentary artifacts without issuing
an alarm. Settings include 0PR Delay, 5PR Delay, or 10PR Delay.
2. SPD Settings—OxiMax SPD™ Alert (SPD) setting
a. SPD Sensitivity Setting—Establishes a threshold at which patterns of desaturation
trigger an alarm.
- Very Sensitive—The default setting of one (1) is very sensitive to desaturation
- Moderately Sensitive—A setting of two (2) is moderately sensitive to
- Less Sensitive—A setting of three (3) is the least sensitive and allows for more
b. SPD Alarm Type—Visual alarm only or both audio and visual SPD alarms
c. SPD Index—The Time column displays the SPD Index, which ranges from a value of 0
to 31. Used by Nellcor staff.
