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 45 to operate at higher temperatures
than intended.
When operating the Vivo 45, make sure that the air inlet and filters are not obstructed
or occluded.
Risk of Insufficient Ventilation
Insufficient ventilation may cause transient hypoxia.
Do not use high resistance bacteria filter at the air outlet of the Vivo 45. High resist-
ance bacteria filters placed between the air outlet and the patient interface may inter-
fere with the operation of the patient disconnect function. It may also interfere with
the device trigger function.
When adding, changing or removing any kind of filter, always reassess the settings,
including alarm settings and perform a pre-use test.
WARNING!
Risk of Cross-Contamination
Deep tissue or mucosal contact with infectious agents may cause infections.
If the Vivo 45 is used by several patients, a low resistance bacteria filter shall be used
between the air outlet and the patient circuit, for preventing patient cross-contamina-
tion. Reuse of bacteria filter, patient circuit or mask may expose patients to conta-
gious agents.
2.6 Humidification
WARNING!
When adding or removing an HME (Heat and Moisture Exchanger, artificial nose) or
HCH (Hygroscopic Condenser Humidifier), always reassess the settings, including
alarm settings, and perform a pre-use test.
Risk of Suffocation
When the attachable humidifier is installed, the Vivo 45 must be located below the
patient and on a flat surface. This is to prevent personal injury from accidental spill-
age or from excess water or condensation flowing down the patient tube and into the
patient’s mask. Extra cautions should be taken for patients who are unable to guard
their airways or cannot pull off the mask.
When using the humidifier or a nebuliser any patient air filter will need more frequent
replacement to prevent increased resistance or blockage.
