Alarm System Of Carina - Dräger Carina Instructions For Use Manual

Alarm system of Carina

The alarm system of Carina meets the require-
ments of the IEC 60601-1-8 standard.
The optical and acoustic alarm signals include:
– Flashing or permanently lit LEDs
– On-screen display of alarm messages
– Acoustic main alarm and acoustic auxiliary
alarm (also used as power supply failure alarm).
The alarm system is designed so that the user can
recognize the alarm messages from a distance of
1 m (39 in). The specified volume levels for the
alarm signal apply to a distance of 1 m (39 in) in
front of the device and at a height of 1.5 m (59 in).
For information on the volume levels of the acoustic
main alarm for the individual alarm priorities, see
chapter "Monitoring functions" on page 129.
The alarm system does not feature any configur-
able alarm presets or default alarm presets. For the
factory settings for the alarm limits, see page 84.
Carina has a nurse call interface which can be used
for a distributed alarm system. According to
IEC 60601-1-8, this distributed alarm system is not
suitable for secure transmission of alarms. Thus
data transfer by means of the nurse call is not a
substitute for regular checking of the notifications
on the device screen. Each device in the alarm sys-
tem connected to this interface must be labeled
with a warning that the connected device does not
guarantee secure reception of the alarm signals.
The alarms are indicated acoustically and optically
by the device without any additional delay immedi-
ately after an alarm condition has been detected.
NOTE
Some alarm conditions are based on time-de-
pendent parameters and are not detected imme-
diately. For additional information, see chapter
"Alarm delays" on page 136.
Instructions for use Carina SW 3.2n
According to IEC 60601-1-8, when there are multi-
ple simultaneously active alarms with the same pri-
ority, the intelligent Carina alarm system displays
the one with the highest urgency on the screen.
The list of alarm conditions and their priorities can
be found in the chapter "Alarm – Cause – Remedy".
All the alarm limits that can be set by the user are
shown in the Alarms menu. For a description of
alarm system operation, see chapter "Alarms".
The acoustic alarm signal and alarms transmitted
via the nurse call can be suppressed for a maxi-
mum of 2 minutes with the Audio paused 2 min.
key, see chapter "Suppressing the acoustic alarm
signal and the nurse call" on page 86. A deacti-
vated alarm signal is indicated by a corresponding
symbol in the alarm line on the screen. If an alarm
of higher priority occurs during this time, the acous-
tic alarm signal sounds once, thus informing the
user about the alarm.
The alarm system is activated when Carina is
started. After the selftest the screen shows the last
defined ventilation mode and the last defined venti-
lation parameters. The device is in standby mode.
Before using the device on a patient, observe the
chapter "Getting started".
During operation, all alarm limits and ventilation pa-
rameters are permanently saved and are immedi-
ately available after a restart.
Individual alarm conditions can be deactivated by
the user under certain conditions, see chapter "Set-
ting the alarm limits" on page 84. Deactivated alarm
signals are indicated by a corresponding symbol in
the alarm line on the screen.
Operation is terminated by activating standby
mode, see chapter "Standby mode" on page 77.
The device is then switched off, see chapter "End-
ing operation" on page 78.
