Alarm Messages - ZOE PPM3 User Manual

Managing Alarms
If the alarm condition is still true when the "alarm silence time" expires (as
configured in the Setup Alarms menu), then the backgrounds of the parameter box
and message area will automatically resume flashing and the alarm tone resume as
well. However, if the alarm condition goes away while the alarm is silenced, then
the backgrounds will automatically switch to black and the tone will not resume.
Each alarm condition has an associated "annunciation type." The annunciation
type is one of the following:
• "One-time"
ends once you silence the condition, even if the condition is still true).
• "Persistent"
time" expires, as long as the alarm condition is true.
Alarm conditions that are "one-time" include an unplugged probe, a lead-off and
all NBP alarm conditions. The remaining alarm conditions are "persistent."
The lethal Asystole and Ventricular Fibrillation alarms are both "persistent" and
"latching." What is meant by "latching" is that they require acknowledgment. So
if a patient goes into an asystole or ventricular fibrillation condition and then
returns to a normal sinus rhythm within the HR alarm limits, the "HR Asystole"
or "HR Ventricular Fibrillation" alarms will continue to annunciate until they are
acknowledged with the ALARM SILENCE key. If the patient is in a normal
sinus rhythm at the time the key is pressed, they will not resume. On the other
hand, if the ALARM SILENCE key is pressed when either of these two lethal
alarms first annunciate, they will behave like other persistent alarms.

Alarm Messages

When an alarm condition is active, a text message is displayed in the message
area at the bottom of the display (e.g. "HR lead off"). If there are multiple alarm
conditions, then the messages are displayed in a "round-robin" manner. That is,
one message is displayed at a time. If multiple messages are active, each message
is displayed for approximately 3 seconds at a time. See the Alarm Conditions
section of this chapter for a list of alarm messages.
