2.4 Patient Circuit —Warnings and Precautions
WARNING!
Risk of Insufficient Ventilation
Insufficient ventilation may cause transient hypoxia.
The Vivo 2 ventilator is intended to be used with patient circuits with intentional leak-
age and compliant to ISO 17510. Recommended leak rate: 20 to 50 liters per minute
at 10 cmH2O.
Failure to use a mask or accessory that minimizes rebreathing of carbon dioxide or
permits spontaneous breathing can cause asphyxiation.
Risk of Abnormal Exhalation Volume Measurement
The exhaled volume of the patient can differ from the measured exhaled volume due
to unintentional leaks around the mask.
For correct measurements, minimize unintentional leaks.
Risk of Reduced Safety and Performance
Accessories that have not been tested with the Vivo 2 might affect safety features and
performance negatively. Only use the Vivo 2 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 2.
The responsible organization is responsible for ensuring the compatibility of the ven-
tilator and all parts used to connect to the patient before use.
Risk of Reduced Performance
Filters and patient connected parts must be replaced regularly to ensure correct func-
tion of the Vivo 2.
18 Safety Information
Vivo 2 User’s Manual Doc. 007229 Y-2

Risk of Insufficient Ventilation
Insufficient ventilation may cause transient hypoxia.
Before use:
•Make sure that the patient circuit and joined parts are undamaged and correctly
connected, in order to avoid unwanted leakage.
•Make sure that the leakage port of the circuit or mask is not blocked or obstructed.
This port prevents rebreathing by flushing the exhaled air.
•For active exhalation valve circuits: Check the function of the exhalation valve and
that is not blocked or obstructed.
•The Vivo 2 should be turned on and the function of the leakage port should be
checked before use: The pressurized air from the Vivo 2 causes a continuous flow
of air through the leakage port, enabling flushing of exhaled air.
Risk of Insufficient Ventilation
Unapproved patient circuits may come loose.
To prevent disconnection of the patient circuit or patient circuit system during use,
especially during ambulatory use, only patient circuits in compliance with ISO 5367
or ISO 80601‐2‐74.
Risk of Suffocation
Periodically check for moisture in the patient circuit.
When present, remove the moisture. Before attempting to dry the circuit, disconnect
it from the Vivo 2 to ensure no water flows back into the Vivo 2.
The frequency at which these checks must be performed will depend on the patient’s
condition and the device used. The responsible caregiver should assess this on an
individual basis in accordance with the patient’s needs.
Risk of Suffocation
If the patient needs assistance to take off the patient interface, the patient shall not be
left alone. This is to avoid the risk of re-breathing of CO2 in case of accidental venti-
lator failure.
Do not breathe through the connected patient circuit unless the ventilator is turned
on and operating properly.
Risk of Suffocation
If the patient is using a full face mask (covering mouth and nose), the mask must be
equipped with a safety entrainment valve.
Risk of Constriction
Entanglement with cables or tubing constricting airways may cause asphyxiation.
Do not leave long lengths of air tubing or cables around the top of the bed. It could
twist around the patient’s head or neck while sleeping.
Safety Information 19
Doc. 007229 Y-2 Vivo 2 User’s Manual

Risk of Insufficient Ventilation
Insufficient ventilation may cause transient hypoxia.
The use of equipment such as endotracheal tubes, oral/nasal tubes, adaptors etc. with
small inner diameters or high resistance filters, humidifiers etc. increase 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.
This impact can be reduced by conducting a pre-use test.
Risk of Excessive Carbon Dioxide
Insufficient carbon dioxide removal may cause arterial acidemia.
For reducing the risk of rebreathing CO2, make sure that the leakage port is located
as near the patient interface as possible. This is extra important for treatments with
low pressure, as this reduces the flow through the leakage port.
WARNING!
Risk of Electric Shock
Do not use antistatic or electrically conductive hoses or tubing with the ventilator
breathing system. This could result in electrical shock.
WARNING!
Risk of Cross-Contamination
Patient circuits might get contaminated by exhaled gases. To avoid cross-contamina-
tion, always use a properly cleaned or a new patient circuit when the Vivo 2 is to be
used by a new patient.
NOTE
For masks and accessories, always follow the manufacturer’s instructions.
2.5 Filter Usage —Warnings and Precautions
WARNING!
Risk of Insufficient Ventilation
Insufficient ventilation may cause transient hypoxia.
Replace or clean the inlet filters as specified in the Maintenance chapter.
Using old or clogged filters may cause the Vivo 2 to operate at higher temperatures
than intended.
When operating the Vivo 2, make sure that the air inlet and filters are not obstructed
or occluded.
