Pulse Oximetry (SPO2)
A noninvasive method for continuously measuring oxygen saturation and pulse rate. Hospital
policies, along with the sensor's directions for use, should be followed in care and rotation of
monitored sites. Insure correct sensor is being used for the type of oximetry in your monitor.
To monitor a patient’s SPO2:
1. Apply sensor to appropriate sensor site on patient. SPO2 monitoring commences
automatically.
2. Open the SPO2 menu by pressing softkey next to SPO2 label.

3. Press the ALM ON softkey if alarms are to be activated.
4. Press the ALM LIM softkey to adjust high and low values for saturation.
5. Press the ALM DELAY softkey to toggle between 5 or 10 seconds.
6. Press the LOCK ON softkey to activate C-LOCK (with Nellcor only).
7. Press the MODE softkey to choose averaging time of data (refer to the following tables,
MODE for Masimo, MODE for Nellcor MP204, or MODE for Nellcor MP405).
8. Press PAGE HOME.
NOTE: To turn SPO2 OFF, press the SPO2 OFF softkey. Turning parameter off eliminates
SEARCH message and halts further SPO2 storage into VSC preventing 00% data storage.
MODE for Masimo Averaging Time Application
NORM (standard) 8 seconds Use when patient is relatively
inactive.
FAST 6 seconds Use for fast response
situations such as sleep
studies.
SLOW
Note: Pulse rate will be
displayed in all three SpO
2
monitoring modes.
12 seconds Use during periods of
excessive patient motion.
MODE for Nellcor MP204 Averaging Time Application
NORM (standard, NELLCOR
Mode 1)
5 to 7 seconds Use when patient is relatively
inactive.
FAST (NELLCOR Mode 2) 2 to 3 seconds Use for fast response
situations such as sleep
studies.
SLOW (NELLCOR Mode 3) 10 to 15 seconds Use during periods of
excessive patient motion.
