Risk of Insufficient Ventilation
Insufficient ventilation may cause transient hypoxia.
Do not use high resistance bacteria filter at the air outlet of the Nippy 4. High resistance
bacteria filters placed between the air outlet and the patient interface may interfere 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. A pre-use test is recommended.
WARNING!
Risk of Cross-Contamination
Deep tissue or mucosal contact with infectious agents may cause infections.
If the Nippy 4 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-contamination.
Reuse of bacteria filter, patient circuit or mask may expose patients to contagious 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 Nippy 4 must be located below the
patient and on a flat surface. This is to prevent personal injury from accidental spillage
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 a humidifier or a nebuliser any patient air filter will need more frequent
replacement to prevent increased resistance or blockage.
The ventilator accuracy can be adversely affected by the gas added by the use of a pneu-
matic nebuliser.
WARNING!
Risk of electric shock
If using the protective cover or the carry bag, first remove the attachable water chamber.
Water spillage may cause electric shocks.
WARNING!
The use of a heated wire patient circuit decreases condensation in the patient circuit.
In case of invasive application, the use of an appropriate external heated humidifier or
HME is recommended.
