Using the 9847 Pulse Oximeter
Visible Indicators
Refer to Figure 2 on page 7 for a detailed illustration of the 9847 controls and indicators.
The intended operator's position for correctly perceiving a visual alarm signal and its priority is 1 meter
(3.3 feet), per IEC 60601-1-8.
SpO
Display
2
The SpO
display is the upper numeric display. This 3-digit light-emitting diode (LED) display
2
shows the current oxygen saturation percentage.
Pulse Rate Display
The pulse rate display is the lower numeric display. This 3-digit LED display shows pulse rate
in pulses per minute.
SpO
and Pulse Rate Displays

A pulse oximeter sensor fault will occur if the 9847 pulse oximeter detects:
• a pulse oximeter sensor disconnect,
• a pulse oximeter sensor dislodgment, or
• a pulse oximeter sensor failure.
If a pulse oximeter sensor fault occurs or a sensor signal is no longer detected, a medium
priority equipment alarm is started. A dash ( - ) appears in the left digit of the SpO
The readings that are displayed will freeze for 10 seconds if the sensor fault or inadequate
signal continues. (Also during this medium priority alarm, an audible indicator will occur.)
If the sensor fault or inadequate signal is not corrected, dashes will be displayed in the middle
digit of both the SpO
2
corresponding dash(es) will blink if there was a prior high priority patient alarm. When the
sensor fault or inadequate signal is corrected, the SpO
normal operation.
When the SpO
or pulse rate alarm limits are met or exceeded, a high priority patient alarm
2
condition exists. The corresponding numbers on the display will blink.
When the SpO
or pulse rate alarm limits are met or exceeded, a high priority patient alarm
2
condition exists and the numerical values of the corresponding parameter will blink. (Also
during these high priority alarms, an audible alarm indication will occur.)
If latched for a pulse oximeter medium priority equipment alarm (a sensor fault or inadequate signal), a
single blinking dash will be displayed in the corresponding middle digit of the SpO
display.
The visible and audible indicators will stop when the condition is cleared.
