4. From the Main Menu, press SpO2 (or SpO2/CO2, then SpO2) to display the first SpO
2
menu:
5. Press SIZE to adjust the waveform size for best viewing (1x, 2x, 4x, or 8x).
6. Adjust the placement of the sensor until a good SpO
2
waveform is displayed. A waveform
with artifact may cause erroneous oxygen saturation readings.
7. Press MORE to display the second SpO
2
menu:
8. Press RESPONSE to select the appropriate time required to measure SpO
2
:
9. If the C-LOCK function is desired, press C-LOCK to set it to ON.
C-LOCK synchronizes the pulse oximeter's systole determination to the R-wave to reduce the effects
artifact may have on SpO
2
measurements. Under some conditions you may find more stable SpO
2
readings with C-LOCK set to ON. SYNC appears next to the waveform when synchronization to the
ECG has been obtained. Synchronization takes a few seconds to establish the first time. If C-LOCK is
on and the HR source is SpO
2
, the heart rate source is automatically changed to ECG. An ECG signal
must be present or C-LOCK does not activate.
If you get false SpO
2
alarms with patients with low perfusion states or multiple arrhythmias, try
turning off C-LOCK.
10. Set alarm limits according to your hospital’s standards.
Response Time Indications for Use
NORMAL 5-7 seconds Use for relatively stable patients.
FAST 2-3 seconds Use when patient movement or other artifact is not present.
SLOW 10-15 seconds Use when patients exhibiting movement are preventing
accurate measurement at NORMAL setting.
