Risk of Reduced Performance
Filters and patient connected parts must be replaced regularly to ensure correct function
of the Vivo 3.
Risk of Insufficient Ventilation
Insufficient ventilation may cause transient hypoxia.
Before use:

Risk of Insufficient Ventilation
Incompatible patient circuits may come loose.
To prevent disconnection of the patient circuit or patient circuit system during use, espe-
cially 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 3 to ensure no water flows back into the Vivo 3.
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 indi-
vidual basis in accordance with the patient's needs.
Risk of Suffocation
If the patient needs assistance to remove the patient interface, the patient shall not be
left alone. This is to avoid the risk of re-breathing of CO
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 Suffocation or Barotrauma
In HFNT mode, do not use a sealed patient interface.
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. They could
twist around the patient's head or neck while sleeping.
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 func-
tion. It may also interfere with the device trigger function.
14 Safety Information
User Manual
Make sure that the patient circuit and joined parts are undamaged and correctly
connected, in order to avoid unwanted leakage.
The leakage port of the patient circuit or patient interface prevents rebreathing by
flushing the exhaled air. It should be located as near the patient interface as possi-
ble (this is even more important for treatments with low pressure). Make sure that
it is not blocked or obstructed.
The Vivo 3 should be turned on and the function of the leakage port should be
checked before use:
in case of accidental ventilator
