For Your Safety and that of Your Patients
Strictly follow these Instructions for Use
WARNING
Any use of the medical device requires full
understanding and strict observation of all
portions of these Instructions for Use. The
medical device is only to be used for the purpose specified under "Intended use"
on page 10 and in conjunction with appropriate patient monitoring.
Strictly observe all WARNING and CAUTION
statements throughout these Instructions for
Use and all statements on medical device
labels.
Maintenance
WARNING
The medical device must be inspected and
serviced regularly by properly trained service
personnel.
Repair of the device may also only be carried
out by properly trained service personnel.
Dräger Medical recommends that a service
contract be obtained with DrägerService and
that all repairs also be carried out by them.
Dräger Medical recommends that only authentic Dräger Medical repair parts be used for

compromised.
Refer to the chapter "Maintenance"
on page 95 for additional information.
Accessories
WARNING
Only the accessories indicated on the list of
accessories have been tested and approved
to be used with the medical device. Accordingly, it is strongly recommended that only
these accessories be used in conjunction with
the specific medical device. Otherwise, the
correct functioning of the medical device may
be compromised.
WARNING
Any connected devices, or combination of
devices, not complying with the requirements
mentioned in these Instructions for Use may
compromise the correct functioning of the
medical device. Prior to operating the medical
device, consult the respective documentation
and Instructions for Use of all connected
devices or combination of devices.
Not for use in explosion hazard areas
WARNING
This medical device is neither approved nor
certified for use in areas where combustible or
explosive gas mixtures are likely to occur.
Safe connection with other electrical equipment
WARNING
Electrical connections to equipment, which
are not listed in these Instructions for Use,
should only be made following consultation
with the respective manufacturers. Equipment
malfunction may result as well as risk of
patient injury.
Instructions for Use Oxylog 2000 plus SW 1.n 5
For Your Safety and that of Your Patients
Patient safety
The design of the medical device, the accompanying literature, and the labeling on the medical
device are based on the assumption that the purchase and use of the equipment are restricted to
trained professionals, and that certain inherent
characteristics of the medical device are known to
the trained operator. Instructions, warnings, and
caution statements are limited, therefore, largely to
the specifics of the Dräger design.
This publication excludes references to various
hazards which are obvious to a medical professional and operator of this medical device, to the
consequences of medical device misuse, and to
potentially adverse effects in patients with abnormal conditions.
Medical device modification or misuse can be dangerous.
CAUTION
Have a supply of extra batteries available.
Patient monitoring
Functional safety
The essential performance of the Oxylog 2000 plus
is defined as:
Accuracy of the delivery of ventilation to the patient
or generation of a technical alarm condition.
The operators of the medical device are responsible for choosing appropriate safety monitoring that
supplies adequate information on medical device
performance and patient condition.
Patient safety may be achieved through a wide
variety of means ranging from electronic surveillance of medical device performance and patient
condition, to simple, direct observation of clinical
signs.
The responsibility for the selection of the best level
of patient monitoring lies solely with the medical
device operator.

General WARNINGS and CAUTIONS
For Your Safety and that of Your Patients
The following WARNINGS and CAUTIONS apply to
general operation of the device. WARNINGS and
CAUTIONS specific to subsystems or particular
features appear with those topics in later sections
of the manual.
Note on EMC/ESD risk for the device function
General information on electromagnetic compatibility (EMC) pursuant to international EMC standard
IEC 60601-1-2:
Electromedical devices are subject to special precautionary measures concerning electromagnetic
compatibility (EMC) and must be installed and put
into operation in accordance with the EMC information. Refer to section "Technical Documentation for
the Oxylog 2000 plus according to EMC standard
IEC/EN 60601-1-2" on page 113.
Portable and mobile RF communications equipment can affect medical electrical equipment.
WARNING
Ventilation monitoring is mandatory at all
times! Whenever a patient is connected to the
ventilator, constant attention by qualified
medical staff is required in order to provide
immediate corrective action in case of a
malfunction.
The operator shall not rely on the built-in
monitoring of the ventilator only and must
always assume full responsibility for proper
ventilation and patient safety in all situations.
WARNING
Keep a manual resuscitation bag available!
If a failure is detected in the ventilator and its
life-support functions can no longer be guaranteed (e.g. in case of a power failure or interruption in the medical gas supply), ventilation
must be started without delay with an independent ventilation device (resuscitation bag)
– using PEEP and/or increased inspired O
concentration as necessary.
WARNING
Always use officially approved gas cylinders
and pressure regulators that comply with all
applicable regulations.
WARNING
For proper ventilation, always consider the
dead space of the total ventilation circuit when
setting ventilation parameters,
especially when applying small tidal volumes.
WARNING
Ventilation with increased oxygen concentra-
tions may be harmful to the patient. Oxygen
must be administered by medical professionals only.
2
Installing accessories
CAUTION
Installations to the basic device must be done in
accordance with the Instructions for Use of the
basic device. Make sure that the connection is
securely fitted onto the basic device system.
Strictly follow the Assembly Instructions and
Instructions for Use.
Instructions for Use Oxylog 2000 plus SW 1.n 7
For Your Safety and that of Your Patients
Instructions for Use only available once
CAUTION
Only one copy of the Instructions for Use is
included in the clinical package and should therefore be kept in an accessible location for users.

Assembly
Reusable or disposable hose systems can be used
with Oxylog 2000 plus. Please refer to the "List of
Accessories" section for ordering information.
NOTE
If the type of the hose system used is changed, the
device must be reconfigured. Refer to the
"Configuration" section for additional information.
Dead space
Dead space is an important aspect of ventilation
management:
Dead space ventilation is the portion of the respiratory system, in which no significant gas exchange
occurs. An increase of the proportion of dead space
to alveolar ventilation may lead to an increase of
the retention of carbon dioxide by the patient.
Dead space is present as a component of the
patient’s artificial airway and hose system. If the
volume of the mechanical dead space equals or
exceeds the volume of alveolar ventilation, the
patient may not be able to adequately evacuate
carbon dioxide. Therefore, it is important to properly manage the ventilation perfusion ratio to
ensure effective elimination of carbon dioxide
gases.

WARNING
The rubber disc (A) in the housing may not be
removed, damaged or bent, otherwise the
valve will not work properly and will endanger
the patient.

1 Place the diaphragm (B) in the breathing valve.
Ensure that it is inserted correctly.
2 Fit the cover (A) and turn it approximately 90
clockwise to secure into position.
3 Push the flow sensor (C) into breathing valve.
Note the preferred position as indicated by the
groove.
4 Connect the angled adaptor (D) to the flow sen-
sor.
WARNING
Always use an angled adaptor. If the angled
adaptor is not used, the minute volume may
be measured incorrectly.

Assembly
When using a bacterial filter or HME
NOTE
When using a bacterial filter or HME, measured
flows may deviate from the expiratory flows, as
temperature and humidity of the gas are reduced.
z Connect the bacterial filter or HME to the angled
connector.
WARNING
Bacterial filters increase the exhalation resis-
tance and dead space volume of the ventilation system.
CAUTION
Do not use electrically conductive hoses!
Risk of electric shock.
This can endanger the patient.
