2 Safety Information
2.1 General Use —Warnings and Precautions
WARNING!
Risk of Personal Injury
The Vivo 3 is not designed for life support treatment:
•The Vivo 3 shall only be used by patients with spontaneous breathing.
•The Vivo 3 should not be used for ventilator dependent patients.
Risk of Faulty Treatment
If the patient is admitted to a hospital or is prescribed any other form of medical
treatment, always inform the medical staff that the patient is on mechanical ventila-
tion treatment.
Risk of Insufficient Ventilation
Usage outside the specified operating conditions may cause reduced performance.
The Vivo 3 must only be used in accordance with the operating conditions specified
in this operating manual
Risk of Faulty Treatment
Do not use the Vivo 3 in the event of
•Suspected damage to the device, including the occurrence of Internal Functional
Failure alarms.
•Unexpected patient symptoms during treatment.
•Unexplainable or sudden changes of pressure, performance or sound during
operation.
•Delivered air being abnormally hot or emitting an odor.
Contact your responsible care provider for an inspection.
Risk of Suffocation
Do not remove the protection for the heated patient circuit connector, the connector
can be fitted with the protection in place.
If removed, children can choke or suffocate if swallowing it.
Risk of Asphyxia or Personal Injury
Using incorrect settings may cause personal injury or severe medical conditions, such
as hypercarbia, producing arterial acidemia.
The therapy settings shall be based on a physician’s description. Changes to settings
must be made by authorized clinical personnel only.
16 Safety Information
Vivo 3 Clinician’s Manual Doc. 007232 Y-2

Risk of Faulty Treatment
The responsible organization should periodically reassess the settings of the therapy
for effectiveness.
Risk of Faulty Treatment
Always prepare the Vivo 3 as described in this manual before use.
Risk of Unnoticed Critical Conditions
•All the physiological alarms of the Vivo 3 must be set at safe levels that will effec-
tively warn the user of any risk.
The alarm levels should be assessed considering the patient’s treatment settings.
•Any change of treatment settings or change of components in the ventilation sys-
tem may require readjustment of the alarm levels.
•The alarm sound level should be set to a clearly audible level. Setting the alarm
sound level below that of the ambient sound level can impede recognition of
alarm conditions.
Risk of Unnoticed Critical Conditions
When using the Vivo 3 invasively, physiological alarms, such as the low volume alarm
and the low breath rate alarm, must be carefully set, to ensure safe use.
Risk of Reduced Safety and Performance
Accessories that have not been tested with the Vivo 3 might affect safety features and
performance negatively. Only use the Vivo 3 with accessories approved by
Breas Medical.
Incompatible parts can result in degraded performance and change of pressure
gradient.
If unapproved accessories are used, Breas Medical has no responsibility for the safe
and effective use of the Vivo 3.
The responsible organization is responsible for ensuring the compatibility of the ven-
tilator and all parts used to connect to the patient before use.
WARNING!
Risk of Electric Shock
Modifying or using the ventilator with accessories that are not specified or approved
by Breas may cause cardiac arrhythmia.
The Vivo 3 must only be used in original and unmodified shape and only with acces-
sories specified or approved by Breas Medical.
Inadequate use of device or accessories may cause loss of treatment or decreased
performance.
Safety Information 17
Doc. 007232 Y-2 Vivo 3 Clinician’s Manual

WARNING!
Risk of Burns
Covering breathing tubes with a blanket or heating them with an overhead heater can
affect the quality of the therapy or injure the patient.
CAUTION!
Read the Clinician’s manual thoroughly and understand the operation of the Vivo 3
before operating or using the machine.
Always use the therapeutic pressure setting, as individually determined with the con-
figuration of the equipment and accessories.
Proper placement and positioning of the patient interface is critical to the consistent
operation of this equipment.
Handle the Vivo 3 with care.
Make sure to place and pack the device in a way that prevents unintentional start of
the machine.
Due to the internal battery, the Vivo 3 may start if the Start/Stop button is pressed
even without the mains being connected.
Do not use the Vivo 3 with nitric oxide, helium or helium mixtures. This may affect
patient air flow and volume measurements.

Vivo 3 Clinician’s Manual Doc. 007232 Y-2

2.2 Electricity —Warnings and Precautions
WARNING!
Risk of Electric Shock
High voltage contact may cause cardiac arrhythmia.
•Do not operate the Vivo 3 if it has a damaged power cord, power supply or casing.
•To avoid electrical shock, only clean the Vivo 3 according to instructions in this
manual. Do not soak or immerse the Vivo 3 into any fluids.
•Use the approved power supply units only.
Use of unapproved power supply units may compromise the electrical isolation
and lead to risk of electric shock.
•Do not use more than one multiple portable socket-outlet or extension cord.
If a multiple portable socket-outlet is used, it must not be placed on the floor.
•The operator must not touch accessible contacts of connectors and the patient
simultaneously.
•Nurse Call must only be connected to a safety extra low voltage system with an
isolation from mains voltage which complies with the requirements of IEC 60601-
1.
WARNING!
Risk of Faulty Treatment
Electromagnetic Interference may cause electrical equipment to malfunction.
•The aspects of electromagnetic compatibility must be considered.
–The Vivo 3 should not be used adjacent to or stacked with other equipment; if
adjacent or stacked use is necessary, the Vivo 3 should be observed to verify
normal operation in that configuration.
–Mobile or transportable radio transmitters may interfere with the Vivo 3.
–Further guidance for safe installation of the ventilator can be found in the
chapter about emission and immunity declaration.
•If a portable AC power supply is used, make sure that the voltage variations are
within the operating limits of the Vivo 3.
•Portable RF communications equipment (including peripherals such as antenna
cables and external antennas) should be used no closer than 30 cm (12 inches) to
any part of the Vivo 3, including cables specified by the manufacturer. Otherwise,
degradation of the performance of this equipment could result.
Safety Information 19
Doc. 007232 Y-2 Vivo 3 Clinician’s Manual

2.2.1 Electromagnetic Compatibility and Electrostatic Discharge (EMC and
ESD)
Use of accessories, transducers and cables other than those specified or provided by
Breas could result in increased electromagnetic emissions or decreased electromagnetic
immunity of this equipment and result in improper operation.
Electromagnetic disturbance may impair the safety and performance of the Vivo 3. The
electromagnetic field levels at the Vivo 3 should not exceed 20 V/m.
Unsteady indicated values for delivered volumes or pressures and the occurrence of
alarm conditions without apparent cause may be an indication of loss of performance
due to electromagnetic disturbances.
Measures for keeping electromagnetic field levels low should include but are not be
limited to:
•Normal precautions with regard to relative humidity and conductive characteristics
of clothing in order to minimize the build-up of electrostatic charges.
•Avoiding the use of radio emitting devices (e.g. cellular or cordless telephones,
microwave ovens and high-frequency surgery apparatus) closer than 1 meter to the
Vivo 3.
•Avoiding the use of known sources of Electromagnetic Interference, (e.g. RFID, dia-
thermy equipment), in the presence of the Vivo 3.
Please note some of these RF emitters may not be visible and the Vivo 3 can poten-
tially be exposed to fields from these RF emitters without the user’s awareness. If
abnormal performance of the Vivo 3 is observed, and the RF emitters cannot be
identified and removed, the Vivo 3 may need to be reoriented or relocated.
See the section Emission and Immunity Declaration for detailed information and further
guidance for mitigating electromagnetic disturbance.
2.3 Environment —Warnings and Precautions
WARNING!
Risk of Intoxication
Do not use the Vivo 3 in a toxic environment.
Risk of Faulty Treatment
If a room humidifier is used, place it at least 2 meters away from the Vivo 3.
