Choose the Averaging Period for the Oximetry Parameter
NOTE! SpO
2
averaging to the number of pulse beats over which the SpO
2
value is averaged; pulse
averaging is the number of seconds over which the pulse value is averaged.
The measured values for oximetry (%SpO
2
and PPR) can be determined by averaging the sensor readings over
a selected number of beats or seconds. For example, if you choose SLOW, the measured value displayed for
oxygen saturation (%SpO
2
) will be the average of the oxygen saturation readings over sixteen pulse beats; the
measured value displayed for peripheral pulse rate (PPR) will be the average of the number of pulse beats over
sixteen seconds. See the table below for specific averaging periods using SurgiVet
®
sensors.
To choose the averaging period:
Highlight AVERAGING PERIOD and push the knob to select.
1.
Choose the desired averaging period (FAST, NORMAL, or SLOW) and push the knob to select.

Adjusting the Volume of the Heartbeat Beep Tone
You can set the monitor to issue a beep tone with each detected SpO
2
heartbeat. You can control the volume
of the beep tone, or turn it off. If the monitor detects a valid SpO
2
reading, the pitch of the beep tone will vary
depending on changes in oxygen saturation. See
Choose the Heart Rate Source
in
Chapter 7: ECG
for information
regarding the source of the heart rate.
To adjust the volume of the pulse beep:
Turn the rotary knob on the monitor to move the cursor. On the main menu at the bottom of the display,
1.
highlight SETUP and push the knob to select.
Highlight PARAMETER OPTIONS and push the knob to select.
2.
Highlight PULSE VOL and push the knob to select.
3.
Turn the rotary knob to increase or decrease the volume to the desired level and push the knob to select. A
4.
momentary beep tone will sound at each new level of volume. The lowest volume option is OFF.
Highlight MAIN MENU and push the knob to select.
