Alarms Alarms
A. Parameter Alarms
Individual alarm levels are adjustable for most of the parameters Passport V is capable of
monitoring. In addition, these alarms may be set by the user to either priority level 1 or 2 as
desired.
NOTE: The Heart Rate Alarm can be triggered only by the source
identified in the Heart Rate data tile. In some circumstances,
the pulse rate displayed in the SpO
2
data tile may differ
from the heart rate displayed in the heart rate data tile.
When the Passport V detects that the SpO
2
pulse rate is in
violation of the heart rate limit settings, the pulse rate data
will flash over a red background, but the audio alarm will
not sound.
B. Invalid Heart Rate Alarm
The Invalid Heart Rate Alarm occurs if the selected heart rate source is no longer able to
detect a heart rate. The
Passport V may display a message to help identify the cause of the
alarm (e.g., “Lead Off” , “Sensor Off” ). The Invalid Heart Rate Alarm is a priority 1
alarm.
C. Apnea Alarm
The Apnea Alarm is active when respiration is being monitored. The Apnea Alarm will be
triggered if respiration is not detected for a time period longer than set in the Alarm Setup
menu. The Apnea Alarm can be set as a “Latched” or “Non-latched” alarm via the
Installation Menu .
When “Apnea Latch” is set to “Off”, the Apnea Alarm will silence and cancel itself if patient
breathing is again detected.
When “Apnea Latch” is set to “On” (default), the Apnea Alarm will not be silenced unless the
operator acknowledges the alarm by pressing the Silence or Silence All keys. The visual
Apnea Alarm indications will not be cancelled unless patient breathing resumes.
The Apnea Alarm is a priority 1 alarm.
D. Arrhythmia Alarms
Arrhythmia Alarms are identified in the upper area of the screen.
“Lethal” Arrhythmia Alarms (“Asystole”, “V-Fib”, and “V-Tach”) are priority 1 alarms that are
latched. Even after the alarming condition is resolved, a latched alarm will continue until it is
acknowledged by pressing the Silence or Silence 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 silenced for the duration that is selected from the “Silence For” list in the Alarm
Setup menu, but the alarm message will continue displaying in the message area in the
upper part of the screen. If a new lethal condition occurs while the initial lethal alarm is
silenced, the new lethal alarm will not break through but not be silenced. If the lethal
condition is resolved while the alarm is silenced, the alarm will be terminated.
