12-10 Infinity Vista VF6
12 PULSE OXIMETRY
Pulse Tone Volume
When SpO
2
is selected as the tone source, the pulse tone changes with the level of
arterial oxygen saturation. Low saturation levels result in low pitched tones; high
saturation levels result in high pitched tones. If SpO
2
is selected as the tone source but
is not currently being measured, no pulse tones are heard. You can adjust the pulse
tone volume between 10% and 100 % (or turn the pulse tone off).
STEPS: Selecting the Pulse Tone Volume
1. Click on the SpO2 parameter box.
2. Click on
Tone Volume.
3. Select the desired setting and click the knob.
NOTE: If you select a Tone Volume higher than the speaker volume of the monitor,
the Tone Volume is that of the speaker volume. If you select a lower setting, the pulse
tone sounds at the selected volume.
