Alarm messages
This chapter describes how to respond to ventilator alarms. It also lists, in
alphabetic order, messages displayed by the ventilator when it detects alarm
conditions.
7.1 Alarm classifications
Alarms in the 700 Series Ventilators are classified by priority (
high-priority
or
medium-priority
); this classification determines how the ventilator responds
(Table 7-1). Some alarms are triggered by a ventilator setting or patient
condition, and they can occur in the usual course of patient care. Others are
triggered by the ventilator’s built-in ongoing tests (BIOT) and may indicate that
the ventilator requires service; some of these are known as
technical alerts
. When
the ventilator declares a technical alert, it not only displays a message, but it also
places an associated diagnostic code into the alert log (Section 4.1.4).
NOTE:
The highest-priority active alarm always flashes on the first line of the
message window. If no alarm is active, the first line displays the highest-
priority alarm that was automatically reset. You can use the menu function
to view all remaining active and autoreset alarms (see the
700 Series
Ventilator System Operator’s Manual
for more information on the MENU
key).
