7.1 Introduction
The Servo-i Ventilator System is equipped
with an alarm system to help ensure patient
safety. Visual and audible alarms warn
about:
• patient breathing problems
e.g., apnea
• power problems
e.g.,
loss of AC power
• problems with gases e.g., low supply
pressure
• hardware problems
e.g.,
overheating
• software problems e.g., memory failure
This chapter describes general responses to
alarms, provides the procedure for setting
alarm limits (see also the
Operation
Overview
chapter), and lists breathing-
related alarm settings along with their
allowed ranges.
The
Power Supply chapter describes power
supply-related alarms.
The
System Messages
chapter lists all alarms
along with possible causes and remedies.
WARNING!
The default setting of the high
airway pressure alarm is 40 cmH
2
O. It is
important to adjust this setting as
appropriate to avoid excessive airway
pressures.
Important: Those responding to alarms must
be health care professionals who have
experience in ventilation treatment and who
have been trained in the use of the Servo-i
Ventilator System.
7.1.1 Alarm Output Connection
Option
If your system is equipped with the alarm
output connection option, high and medium
priority alarms can be transferred to an
external signal system. The alarm output
signal is active as long as the audio alarm is
active on the ventilator.
WARNINGS!
• Never leave the patient unattended; the
external alarm is designed to alert those
already in attendance.
• The alarm output is a nonguaranteed
alarm according to IEC 60601-1-8 and it is
recommended that users establish a Pre-
Use Check routine for this application.
7.1.2 Visual Alarm Display
When an alarm is activated, the following
information is supplied on the screen.
1. A text message explaining the cause of
the alarm flashes in the alarm message
area. The alarm with highest priority is
displayed first.
2. The corresponding measured value or
set value box flashes and an arrow
points at the exceeded limit.
Note:
Two bells in the alarm message area
indicate that more than one alarm is
activated.
