Additional Information for Telemetry Products
When SpO
2
alarms are enabled, a bell symbol is displayed between the SPO2
label and the SpO
2
measured saturation value. When an SpO
2
alarm is detected,
the displayed parameter value blinks yellow if the alarm priority is Low or Medium,
and blinks red if the alarm priority is High.
Selecting Data Averaging Period
Use this feature to smooth the oximetry saturation value by averaging patient
input values over 4-, 8-, or 16-seconds. The default value is 8-seconds.
• For non-telemetry products, the data averaging period is displayed in the
menu prompt line of the AVERAGING menu.
• For telemetry products, refer to the 90343, 90347, 90478, 90479-A Ultraview
Digital Telemetry Service Manual (P/N 070-0744-xx) for setting up the data
averaging period.
Using SpO
2
with Intra-Aortic Balloon
Pumps
Enabling the intra-aortic balloon pump (IABP) feature informs the SpO
2
software
that an IABP is in use. The SpO
2
software must differentiate between true arterial
pulsations and those produced by the IABP. With the IABP feature enabled, the
transmitter excludes the IABP-generated pulsations from the calculation for SpO
2
.
The IABP feature also may be useful with patients experiencing irregular heart
rhythms. Enabling the IABP feature permits the transmitter to reject irregular
pulses, providing a more accurate SpO
2
measurement.
!
• When the IABP feature is enabled, the pulse rate obtained from
SpO
2
may not match the heart rate obtained from ECG.
• In cases of excessive patient motion or artifact, the accuracy of
the SpO
2
measurement may be compromised when the IABP
feature is enabled.
• (90343 only) When the IABP operation is selected, the SPO2
status key in the Channel Format menu indicates IABP. The
Service Manual describes how to configure the telemetry
transmitter for use with an IABP.
