2 Safety Information
2.1 General User Precautions
• When a ventilator-dependent patient is treated outside of a health
care facility (e.g., in the home setting) there should always be a trained
caregiver present to respond to alarms or conditions the patient is
unable to solve on his or her own (e.g., troubleshooting alarm condi-
tions and taking appropriate corrective action). The home medical
equipment provider will ensure that the family caregivers are appro-
priately trained in responding to alarms and taking appropriate cor-
rective action prior to the patient’s discharge from the health care
facility to the home, and will provide ongoing training to new car-
egivers as required or indicated.
• Always have immediate access to an alternative means of ventilation,
which is ready for use, to avoid patient death or serious injury.
• Failure to have an alternate means of ventilation can result in serious
injury or patient death if ventilator fails.
• The Vivo 65 must be turned off and on at least every 90 days. This is
necessary in order for the Vivo 65 to perform a complete self-test.
The self-test automatically tests the alarm sound and certain compo-
nents.
• If you are admitted to a hospital or are prescribed any other form of
medical treatment, always inform the medical staff that you are on
mechanical ventilation treatment.
• Vivo 65 must only be used:
– for the intended treatment in accordance with this operating manual
and with the instructions given by the responsible clinical personnel;
– in accordance with the operating conditions specified in this operat-
ing manual;
– in original and unmodified form and only with accessories specified
or approved by Breas Medical AB.

8 Safety Information
Vivo 65 users manual Doc. 006088 En-US U-1b
• Do not use the Vivo 65 in the event of suspected damage to the
device, unexplainable or sudden pressure, performance or sound
changes during operation, or if the delivered air from the Vivo 65 is
abnormally hot or emits an odor. In these cases, contact the patient’s
responsible care provider for an inspection.
• The Vivo 65 may not work properly if any part has been dropped,
damaged or submerged in water.
• Inadequate use of device or accessories may cause loss of treatment
or decreased performance.
• The Vivo 65 therapy settings must always be based on medical advice
and must be carried out by authorized clinical personnel only. When
changing treatment settings or changing to another device, a clinical
assessment must be performed to determine if blood gas measure-
ment needs to be performed.
• Always perform the procedure “Inspecting the Vivo 65 before Use”
on page 39 before use.
• The Vivo 65 can be used for life-supporting treatment provided an
emergency equipment (e.g. resuscitation bag) is available, and that
one of the following configurations is used for surveillance of venti-
lator-dependent patient breathing:
– Dual limb patient circuit and insert with integrated exhalation valve:
The Vivo 65’s internal measurement and monitoring of exhaled vol-
ume must be supervised.
– Single limb with leakage patient circuit: The Vivo 65’s monitoring of
exhaled volume must be supervised
– Single limb with exhalation valve patient circuit: The CO2sensor or
an external EtCO2monitor (capnometer) must be used. The CO2
sensor must be connected between the patient and the exhalation
valve to be able to measure exhaled gases. The CO2monitor shall ful-
fil the ISO 80601-2-55 standard (Medical electrical equipment - Par-
ticular requirements for the basic safety and essential performance of
respiratory gas monitors).

2.2 Electrical Safety
• Do not operate the Vivo 65 if it has a damaged power cord or casing.
• To avoid electrical shock, disconnect the electrical supply to the
Vivo 65 before cleaning. Do not immerse the Vivo 65 into any fluids.
• If a multiple portable socket-outlet is used, it must not be placed on
the floor.
• Do not use more than one multiple portable socket-outlet or exten-
sion cord.
• 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 sys-
tem with an isolation from mains voltage which complies with the
requirements of IEC 60601-1.
• The aspects of electromagnetic compatibility must be considered.
The Vivo 65 should not be used adjacent to or stacked with other
equipment; if adjacent or stacked use is necessary, the Vivo 65 should
be observed to verify normal operation in that configuration. Mobile
or transportable radio transmitters may interfere with the Vivo 65.
Guidance for safe installation of the Vivo 65 can be found in “Emis-
sion and Immunity Declaration” on page 192.
• If a portable AC power supply is used, make sure that the voltage var-
iations are within the operating limits of the Vivo 65.
See “Power Supply” on page 188 for AC operating limits.
• Use of accessories, transducers and cables other than those specified
or provided by Breas could result in increased electromagnetic emis-
sions or decreased electromagnetic immunity of this equipment and
result in improper operation.

• Avoid using RFID devices closer than 1 meter to the Vivo 65.
• Avoid using the Vivo 65 within 1 meter of electronic article surveil-
lance (EAS) system antennae.
• Unsteady indicated values for delivered volumes or pressures and the
occurrence of alarm conditions without apparent cause may be an
indication of a loss of performance due to electromagnetic distur-
bances. Follow the instructions above and the guidance provided in
“Emission and Immunity Declaration” on page 192 to mitigate the
effects of electromagnetic disturbances.
• The Vivo 65, any accessories and all replaced parts must be disposed

tions.

13Safety Information
Vivo 65 users manual
Doc. 006088 En-US U-1b
2.4 Usage of Patient Circuit
• The Vivo 65 can be used with the following circuits:
– Dual limb circuit (Adult use, 22 mm), connected to an integrated
active exhalation valve
– Dual limb circuit (Pediatric use, 15 mm), connected to an integrated
active exhalation valveSingle limb circuit (with optional single limb
insert) for an external active exhalation valve
– Single limb circuit (with optional single limb insert) for an external
leakage port
– Circuit with mouthpiece interface
• For the Vivo 65 to deliver treatment according to settings, it is impor-
tant that the selection of the patient circuit type is correctly set.
• The pressurized air from the Vivo 65 causes a continuous flow of air
to exhaust from the leakage ports or exhalation valve, flushing
exhaled gas from the circuit. The Vivo 65 should be turned on and
the function of the leakage port or exhalation valve should be
checked before use.
• Do not breathe in the connected patient circuit unless the Vivo 65 is
turned on and operating properly.
• Do not use patient hoses or tubes made of static or electrically con-
ductive material.
• Always use a new patient circuit when the Vivo 65 is to be used by a
new patient.
• Always make sure that the patient circuit and joined parts are undam-
aged and correctly connected, in order to avoid unwanted leakage.
• Always perform a pre-use test when the patient circuit or insert is
replaced or modified.
• Patient connected parts and all filters must be replaced regularly to
ensure correct function of the Vivo 65. All replaced parts must be
disposed of according to local environmental regulations regarding
the disposal of used equipment and parts.

14 Safety Information
Vivo 65 users manual Doc. 006088 En-US U-1b
• Patient circuits used with the Vivo 65 shall have the following char-
acteristics:
– Length: Max 6 feet (2 meters).
– Connector: 22 mm.
– Resistance: Max 2 mbar at 40 l/min.
If an active exhalation valve is used:
– Inner diameter of the exhalation valve control pressure tube: 3 mm.
– The exhalation valve must be of the type that is open (letting the
exhaled patient air out) when unpressurized by the control pressure.
By conducting a pre-use test (see “Performing the Pre-use Test” on
page 40), the compatibility of the complete patient circuit configura-
tion with the Vivo 65 can be verified. If a pre-use test is successfully
performed the circuit configuration meets the required characteris-
tics.
• The leakage from the mask or leakage port should be at least 12 l/
min at 4 cmH2O, to prevent rebreathing of exhaled air. The recom-
mended leakage is 20 to 50 l/min at 10 cmH2O pressure.
• Periodically check for moisture in the patient circuit. When present,
remove the moisture. Before attempting to dry the circuit, disconnect
it from the Vivo 65 to ensure no water flows back into the Vivo 65.
• When using the Vivo 65 invasively, the low volume alarm and the low
breath rate alarm must be carefully set, to ensure safe use.
• The use of equipment such as endotracheal tubes, oral/nasal tubes,
adaptors, etc. with small inner diameters or high resistance filters
(such as humidifiers) increases the resistance in the patient circuit
which may interfere with the operation of the patient disconnect
function. It may also interfere with the device trigger function. The
impact can be reduced by conducting a pre-use test properly. (See
“Performing the Pre-use Test” on page 40.)
• In case of invasive application, the use of an appropriate external
heated humidifier or HME (Heat and Moisture Exchanger, artificial
nose)/HCH (Hygroscopic Condenser Humidifier) is recommended.

15Safety Information
Vivo 65 users manual
Doc. 006088 En-US U-1b
• Make sure that the exhalation valve or the leakage port is never
blocked or obstructed.
• Do not leave long lengths of air tubing around the top of the bed. It
could twist around the patient’s head or neck while he or she is sleep-
ing.
• Always follow the instructions of the mask manufacturer.
• The Vivo 65 is equipped with a rebreathing alarm. The alarm is not a
substitute for operator vigilance in ensuring that the leakage port or
exhalation valve remains clear at all times. Periodically check the
patient circuit during therapy.
• In general, as pressure decreases, the potential of rebreathing
increases. Lower pressures produce less flow through the leakage
port which may not clear all CO2from the circuit to prevent
rebreathing.
• To reduce the risk of rebreathing CO2, make sure that the leakage
port or active exhalation valve is present as close as possible to the
patient connection.
• Contact Injuries: Skin irritation may occur due to prolonged expo-
sure to either a mask (if used) or the SpO2module.
The Vivo 65 and its packaging do not contain any natural rubber latex.

16 Safety Information
Vivo 65 users manual Doc. 006088 En-US U-1b
2.5 Usage of Filters
• Always use the Vivo 65 with patient air inlet filters installed. Only use
the Vivo 65 with accessories recommended by Breas.
• Replace or clean the filters regularly to ensure correct function of the
Vivo 65. Failure to replace or clean a dirty filter may cause the
Vivo 65 to operate at higher temperatures than intended. A dirty fil-
ter may be caused by dust or animal hair in the home environment.
• When operating the Vivo 65, make sure that the air inlet and filters
are not obstructed or occluded.
• The use of a high resistance bacterial filter on the output of the device
may interfere with the operation of the patient disconnect function.
It may also interfere with the device trigger function. The impact can
be reduced by conducting a pre-use test properly. (See “Performing
the Pre-use Test” on page 40.)
• When adding or removing any kind of filter, always perform a pre-
use test.

17Safety Information
Vivo 65 users manual
Doc. 006088 En-US U-1b
2.6 Humidification
• Humidification must only be used if this has been prescribed by your
physician. The Vivo 65 therapy settings must always be prescribed by
a physician or other licensed health care professional, and be carried
out by authorized clinical personnel.
• When using an external heated humidifier, it should be located below
the Vivo 65 and the patient to prevent injury from accidental spillage.
• When using a humidifier or nebulizer, any patient air filter will need
more frequent replacement to prevent increased resistance or block-
age.
• During transportation of the Vivo 65, the humidifier must be discon-
nected.
• If the condensation in the patient circuit is excessive, the use of a
heated humidifier may require the installation of a water trap in the
circuit. The water trap prevents any condensated water in the patient
circuit from running into the patient airways and causing personal
injury.
• When adding or removing a HME (Heat and Moisture Exchanger,
artificial nose) or HCH (Hygroscopic Condenser Humidifier), always
perform a pre-use test.
• Any humidifier connected to the Vivo 65 must comply with
ISO 8185.
• Any HME connected to the Vivo 65 must comply with ISO 9360.
• The use of an HME or an external humidifier may require readjust-
ment of the Vivo 65 low-pressure alarm.
• Certain HMEs and HCHs are sufficient to provide humidification
when the Vivo 65 is used invasively. Check specific suppliers’ recom-
mended use.
The Vivo 65 has been tested and validated with the Fisher & Paykel
MR850 heated humidifier.

18 Safety Information

responsible for the performance and safety of the Vivo 65. Further-
more, no guarantees will be valid.

19Safety Information
Vivo 65 users manual
Doc. 006088 En-US U-1b
2.8 Usage of Oxygen
• Always follow the oxygen provider’s instructions.
• The presence of oxygen can speed up combustion of inflammable
materials.
• At a fixed flow rate of supplemental oxygen flow, the inhaled oxygen
concentration will vary, depending on the pressure delivered, the
patient’s breathing pattern, mask selection and leak rate. To monitor
the oxygen concentration the FiO2sensor (part no. 006347) is rec-
ommended.
• When oxygen is used with the Vivo 65, the oxygen flow must be
turned off when the Vivo 65 is not operating. Oxygen delivered into
the patient tubing may accumulate within the machine enclosure.
Oxygen accumulated in the machine enclosure will increase the risk
of fire.
• Do not use a humidifier between the oxygen source and the ventila-
tor, in order to humidify the oxygen flow.
• Ventilate the room adequately.
• Do not smoke in a room where oxygen is being used.
• Naked light bulbs and other sources of ignition must be kept a mini-
mum of 6 feet (2 meters) away from the oxygen cylinder or any part
of the patient circuit.
• Supplemental oxygen with a flow up to 15 l/min can be added by an
oxygen source with rotameter such as oxygen cylinder or a central
oxygen supply system.
• Do not use aerosols or solvents close to the oxygen supply, even
when the oxygen supply is shut off.

20 Safety Information
Vivo 65 users manual Doc. 006088 En-US U-1b
• Supplemental oxygen flow must not exceed 15 l/min. or 100 kPa.
• The oxygen concentration in the delivered air has influence on the
volume measurement of the Vivo 65. This measurement is based on
a normal oxygen concentration of 21%. If the oxygen concentration
is higher, the monitored inspired volume will deviate from the actual
volume as follows:
– 40% oxygen concentration: -2.5% deviation
– 60% oxygen concentration: - 5% deviation
– 80% oxygen concentration: -7.5% deviation
