1.2.1.1 Overview
The following table gives an overview of the integrated safety functions which come into
effect if problems occur during operation:
Fault Safety function
Leakage Pressure regulation and PEEP compensation
– In mechanical ventilation modes, the set PEEP is actively
adjusted even in the case of small leaks.
– In pressure-controlled modes, the pressure is controlled
during the entire respiratory cycle.
Mains power supply
failure
Uninterruptible power supply provided by internal battery
– Device runtime in battery operation see Instruction for Use
– Automatic deactivation of the breathing system warmer to
increase battery runtime

the gas supply
– Mechanical ventilation with ambient air possible (the hose
with the breathing bag will have to be removed for this)
– No anesthetic agent delivery from the connected vaporizers
possible; switch to intravenous anesthetic agent required
Flow measurement
failure
– Mechanical ventilation can be continued.
– Restrictions with regard to displayed measured values, mea-
surement accuracies, and when triggering mandatory
breaths are possible.
Failure of fresh-gas
delivery (electroni-
cally controlled mixer
only)
– Emergency O2delivery
see Instruction for Use
– Anesthetic agent delivery from connected vaporizers possi-
ble
– All ventilation modes are available.
Alternatively:
– Backup manual mode
Ventilator failure – Manual ventilation or spontaneous breathing possible
– Fresh-gas delivery available
– Anesthetic agent delivery from connected vaporizers possi-
ble

does not respond to
operation or has
failed)
If backup manual mode is activated:

The device can be used with Infinity ID breathing hoses or conventional breathing hoses. If
no leakage test has yet been performed after switching on the device, hose compliance and
hose resistance will automatically be adopted when Infinity ID breathing hoses are
connected.

Assembly and preparation
2. Assemble the breathing circuit and connect it to the Y-piece and nozzles on the
breathing system. Observe the following information: "Permissible hose configurations",
page 16.
When attaching or removing the breathing hoses, always hold them by the connection
sleeve and not by the hose itself.
2.1.1.1 Permissible hose configurations
The permissible hose configurations are marked with an "X" in the following table:
35636
Configuration Adult Ped. Neo.
A breathing system filter or an HME filter
between Y-piece and patient; sample line
connected to the filter
XX
One breathing system filter on each of the
inspiratory port and expiratory port; sample
line connected to the Y-piece
XX
– One breathing system filter each on the
inspiratory port and expiratory port; sam-
ple line connected to a connector as
close as possible to the patient
– Extract the sample gas at a connector in
which the gas has laminar flow without
turbulence.
– If no filter can be used at the expiratory
port (e.g., if there is intrinsic PEEP due to
Air trapping), reprocess the breathing
system after every patient.
Perform the reprocessing in accordance
with the reprocessing instructions sup-
plied with the product.

Quick reference guide | Atlan SW 2.0n 17
Assembly and preparation
When taking a gas sample at a connector
located as close as possible to the patient
– One breathing system filter on the inspi-
ratory port and one on the expiratory port
– Use only heat and moisture exchangers
(HMEs) between the Y-piece and the
patient that are listed in the list of acces-
sories.
– Do not use fine-pored filters or HME fil-
ters between the Y-piece and the patient.
– Set the alarm limits for MV low and Paw
to suitable values. Observe the following
information: "Optimization of the sample
gas quality", page 40.
XX
When using fine-pored filters between the Y-
piece and the patient
– Do not connect the sample line between
the tube and the filter. Instead, connect it
to the filter or the Y-piece.
