SpMet softkey
Pressing this softkey will instantly display the SpMet
reading in the CO-oximetry data field. It will display for 10
seconds, then revert to the SpO
2
reading. This softkey
will not appear if Auto Display is enabled.
Alarms
The E Series CO-oximetry option provides user
programmable “out of range” alarms for SpO
2
, SpCO and
SpMet. See “Default Settings” on page 10 for low and
high alarm limit default values and ranges.
Once the SpO
2
, SpCO or SpMet value reaches the high
or low limit, there is a 4 second delay before the alarm
occurs.
When an alarm occurs, the alarming parameter’s value
will be highlighted and the alarm symbol will flash in the
CO-oximetry data field. If more than one alarm occurs at
the same time, the multiple alarms will alternate on the
display.
When monitoring a patient’s heart rate using ECG, the
high heart rate alarm limit range is 60 to 280 bpm, with a
default setting of 150 bpm. When monitoring the heart
rate using pulse oximetry, however, the maximum high
heart rate alarm limit is automatically lowered to 235 bpm
if it was previously set higher for ECG monitoring. The
unit restores the original high heart rate alarm limit
setting when ECG monitoring resumes.
When the SpO
2
alarm state is set to AUTO, the unit
automatically sets the SpO
2
alarm limits to 95% and
105% of the patient’s currently measured saturation (the
maximum setting being 100%). The auto alarm limits are
set only if valid measurements are present for the vital
sign.
Auto alarm limits are not applicable to SpCO and SpMet.
See the E Series Operator’s Guide for details on
enabling, disabling, and suspending alarm functions on
the E Series unit.
Automated External Defibrillator (AED)
Operation
E Series AED units equipped with pulse CO-oximetry
operate in a slightly different way when in Semi-
Automatic Mode:
• The plethysmographic waveform cannot be
displayed.
• Heart rate alarm functions are disabled (although
SpO
2
, SpCO and SpMet alarm functions are
operational). Background ECG analysis functions
continue to operate as described in the AED section
of the E Series Operator’s Guide.
• You cannot change alarm limit settings; only the
default alarm limits are available.
Checkout Procedure
Perform the following checkout procedure daily to ensure
that the pulse CO-oximetry option is functioning properly.
Use a reusable sensor when performing this procedure.
1. Attach the sensor to your finger and connect the
patient cable to the pulse CO-oximetry connector at
the back of the E Series unit (as described in
“Applying a 2-piece Reusable Sensor/Cable” on
page 4).
2. Turn the selector switch to MONITOR (ON for AED
units, then select Manual mode).
3. With alarms enabled, verify that the patient alarms
are functional by adjusting the high and low SpO
2
limits until the unit:
• Emits a continuous audio tone.
• Highlights the alarming parameter's value and
flashes the alarm symbol on the display.
4. Disconnect the ECG cable and verify that your pulse
rate is equal to the rate that appears on the E Series
heart rate display.
5. Verify the sensor alarms are functional by unplugging
the sensor from the E Series unit. Make sure the unit:
• Displays the CHECK SPO2 SENSOR message.
• Emits a two-beep audio tone.
6. Verify the plethysmographic waveform display by
pressing the Wave 2 softkey and ensuring that the
waveform repeats at your pulse rate. (not applicable
to AED units).
7. If your E Series unit is configured for SpCO, attach a
Rainbow sensor to your finger and connect to the
pulse CO-oximetry connector at the back of the unit.
8. Press the Param softkey. Verify that the CO-Oxim.
parameter is highlighted. Press the Enter softkey.
9. Press the SpCO softkey and verify that the SpCO
value is correctly displayed.
