Passport 12/Passport 8 Operator’s Manual 7-3
7.3.3 Flashing Numeric
If an alarm triggered by an alarm limit violation occurs, the numeric of the measurement in alarm will flash every second,
and the corresponding alarm limit will also flash at the same frequency indicating the high or low alarm limit is violated.
7.3.4 Audible Alarm Tones
The alarm tone is distinct from heart beat tone, keystroke tone and pulse tone in frequency. This monitor has three alarm
tones and patterns: ISO, Mode 1 and Mode 2. For each pattern, the alarm tones identify the alarm levels as follows:
ISO pattern:
High level alarms: triple+double+triple+double beep
Medium level alarms: triple beep
Low level alarms: single beep
Mode 1:
High level alarms: high-pitched single beep
Medium level alarms: double beep
Low level alarms: low-pitched single beep
Mode 2:
High level alarms: high-pitched triple beep
Medium level alarms: double beep
Low level alarms: low-pitched single beep
7.3.5 Alarm Status Symbols
Apart from the aforementioned alarm indicators, the monitor still uses the following symbols telling the alarm status:
indicates alarms are paused.
indicates alarm is reset.
indicates the alarm sound is turned off.
indicates individual measurement alarms are turned off or the system is in alarm off status.
NOTE
When multiple alarms of different levels occur simultaneously, the monitor will select the highest level
alarm, light the alarm lamp and give alarm sounds accordingly, while all the alarm messages are displayed
circularly on the screen.
Some physiological alarms, such as Asystole, are exclusive. They have identical alarm tones and alarm lights
with normal high level physiological alarms, but their alarm messages are displayed exclusively. That is,
when an exclusive physiological alarm and a normal high level physiological alarm are triggered
simultaneously, only exclusive physiological alarm messages will be displayed.
