LIFEPAK 15 Monitor/Defibrillator Operating Instructions
To monitor SpCO or SpMet:
1. Perform Step 2 through Step 5 above.
2. Verify that an SpCO/SpMet sensor is in use. Only Rainbow sensors are capable of reading
SpCO/SpMet.
3. Encourage the patient to remain still.
4. To quickly obtain SpCO or SpMet value, press
PRINT
. If dashes (---) appear on printout
instead of values for SpCO or SpMet, allow a few more seconds for measurement to be
obtained.
or
To display SpCO or SpMet:
•
Use the
SPEED DIAL
to select the SpO
2
area.
• Select
PARAMETER
from menu.
•
Select
SPCO
or
SPMET
. Selected value displays for 10 seconds.
Note:
SpCO and SpMet monitoring are not intended for use under patient motion or low
perfusion conditions.
SpCO/SpMet Advisory
If the SpCO or SpMet reading is above normal limits, indicating a dangerous amount of
carboxyhemoglobin or methemoglobin, an Advisory occurs.
During an Advisory:
•
The elevated SpCO or SpMet value is displayed instead of SpO
2
.
•
The elevated value flashes and the alarm tone sounds.
• One of the following Advisory messages appears in the message area:
Advisory: SpCO > 10%
Advisory: SpMet > 3%
To cancel the Advisory, press
ALARMS
. The SpO
2
area reverts to the SpO
2
reading. The Advisory
message remains on the screen until the elevated value returns to within normal limits or the
device is turned off.
Inaccurate SpO
2
Readings
Carboxyhemoglobin and methemoglobin may
erroneously increase SpO
2
readings. The amount that
SpO
2
increases is approximately equal to the amount of
carboxyhemoglobin or methemoglobin that is present.
