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 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
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.
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 CO , make sure that the leakage port is located
2
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.
