Alarms and Limits

Alarms and Limits
This chapter describes alarms and limits for the Avant 9700 Digital Pulse Oximeter.
High Priority Alarms
High priority alarms are those that require immediate attention to the patient. They
include SpO pulse rate, and low perfusion alarms. On the Avant 9700, high priority
2,
alarms are indicated with rapidly blinking red LED displays when alarm limits are
met or exceeded. In addition, the pulse strength bargraph LED will illuminate red
segments to indicate an active low perfusion alarm.
High priority alarms are sounded as follows: "beep, beep, beep," (short pause),
"beep, beep" (10-second pause).
Medium Priority Alarms
Medium priority alarms are those that signal potential problems with the equipment
or other non-life-threatening situations. On the Avant 9700, medium priority alarms
are indicated with slowly blinking amber displays.
Medium priority alarms are illuminated amber on the Main Alarm LED and on the
appropriate indicator(s) or numeric displays, sometimes displaying an error code to
help the user identify the source of the error.
Medium priority alarms are sounded as follows: "beep, beep, beep," (25-second
pause), "beep, beep, beep."
Watchdog Alarms
Watchdog alarms are loud, two-tone, steadily beeping signals that indicate a
hardware or software malfunction. When a watchdog alarm is activated, it can be
cleared by shutting down the Avant 9700 (press and hold the ON/STANDBY
button for one second). If the watchdog alarm cannot be cleared, remove the battery
and contact your distributor or NONIN Customer Support.
Informational Tones
Informational tones communicate important information. They are typically single
"beeps" or a series of three "beeps." Informational tones include the startup/
initialization tone and the pulse rate tone (which changes in pitch with SpO values).
