Operation Alarms
C. Apnea Alarm
The Apnea Alarm is active when respiration is being monitored. The Apnea alarm is violated
when breathing is not detected for a longer period of time than the apnea delay specified in
the Alarms Menu. When the alarm is silenced by pressing MUTE or MUTE ALL, the alarm
tone will cease to be heard. The mute period, as set in the Alarms Menu, will now begin to
count down. If normal breathing occurs during the selected time frame for “MUTE”, the
Alarms Muted for... message will disappear. Apnea is a Priority 1 alarm.
D. Arrhythmia Alarms (Passport 2 only)
Arrhythmia alarms are defined in section 3.10.
Non-lethal arrhythmia conditions are defined as:
Bradycardia, Irregular Heart Rate (3/5-Lead ECG only)
Pause (View 12 ECG Module only)
Ventricular Rhythm (V-Rhythm), Couplet, Bigeminy, Trigeminy, PVC’s per minute, and
Run.
Once an alarm condition has been triggered for any of these non-lethal arrhythmias, it can
be silenced by pressing MUTE or MUTE ALL. During the muted period, as established in the
Alarms Menu, if a second non-lethal arrhythmia condition occurs, it will be identified in the
message area of the Passport 2 but will not sound an alarm until the preset, mute period of
time has elapsed. Non-lethal arrhythmia conditions are Priority 2 alarms.
Lethal arrhythmia conditions are defined as Asystole, Ventricular Tachycardia, and
Ventricular Fibrillation. Once V-Tach, V-Fib, or Asystole occurs, the alarm is latched. Even
after the alarming condition is resolved, a latched alarm will continue until it is
acknowledged by pressing the MUTE or MUTE ALL key on the front panel keypad. If the
alarm is acknowledged while the lethal condition still exists, the audio portion of the alarm
will be muted for the duration that is selected from the “Mute For” list in the “Alarm Setup”
menu, but the alarm message will remain in message area A. If a new lethal condition occurs
while the initial lethal alarm is muted, the new lethal alarm will not break through and will be
muted for the remainder of the mute duration. If the lethal condition is resolved while the
alarm is muted, the alarm will be terminated.
