Pulse Quality Indicator; No Breath Indicator; Co 2 Bar Graph - Nonin 9847V Operator's Manual

Using the 9847V Pulse Oximeter

Pulse Quality Indicator

CAUTION: The device has motion tolerant software that minimizes the likelihood of
!
motion artifact being misinterpreted as good pulse quality. However in some
circumstances, the device may still interpret motion as good pulse quality.
The Pulse Quality indicator
Pulse Quality indicator changes color to indicate changes in the pulse waveform signal that may affect
the SpO data.
2
The Pulse Quality indicator blinks one of three colors:
• Green indicates the pulse waveform signal is of good quality and the SpO
are accurate.
• Yellow indicates the pulse waveform amplitude is marginal or that the pulse oximeter has detected
artifact. Although the SpO
be considered if the indicator continues to blink yellow frequently. To improve signal quality, try
repositioning the sensor, using a different sensor type, eliminating animal movement, or improving
circulation at the site by massaging the area.
• Red indicates the pulse waveform amplitude is inadequate. During red pulse quality, SpO
pulse rate values are not updated. A high priority animal alarm occurs. After approximately
20 seconds, the values are replaced with dashes indicating that SpO
measurements are not possible. (Also during this high priority animal alarm, the high priority
audible pulse quality alarm sounds if the audible alarms are not disabled.)

No Breath Indicator

The No Breath indicator, a high priority animal alarm, flashes when a breath has not been detected
for a period of time that exceeds the set no breath delay time (measured in seconds). During this
alarm, the high priority audible no breath alarm sounds if the audible alarms are not disabled. (See
"No Breath Alarm" on page 29 for additional information.)
If a CO sensor alarm occurs, existing visible and audible absence of breath indicators latch. However
2
in most cases, during "fixed pitch" breath beep mode, when the airway adapter tube is unsnapped
from the CO sensor, the visible and audible absence of breath indicators stop.
2
When a breath is again detected, the visible and audible no breath indicators stop. The no breath
delay timer is first started when the CO
