Using the 9847 Pulse Oximeter
• Red indicates that the pulse waveform amplitude is inadequate. During red pulse quality, SpO
pulse rate values are not updated. A high priority patient alarm occurs. After approximately
20 seconds, the values are replaced with dashes indicating that SpO
are not possible. (Also during this high priority patient alarm, the high priority audible pulse quality
alarm sounds if the audible alarms are not disabled.)
No Breath Indicator
The visible no breath indicator is a high priority patient visible alarm that flashes when a breath has not
been detected for a period of time exceeding 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
"Audible No Breath Alarm" on page 27 for additional information.)
If a CO
sensor alarm occurs, existing visible and audible absence of breath indicators will latch. In most
2
cases, however, 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 will stop.

When a breath is again detected, the visible and audible no breath indicators will stop. The no breath
delay timer is first started when the CO
