Breas Nippy 4 - Usage of Filters

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.
This impact can be reduced by conducting a pre-use test.
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.
The ventilator is equipped with a rebreathing alarm. The alarm is not a substitute for
operator vigilance in ensuring that the leakage port remains clear at all times. Periodically
check the patient circuit during therapy.
In general, as pressure decreases, the potential of rebreathing increases. Lower pressures
produce less flow through the leakage port which may not clear all CO
2
from the circuit
to prevent rebreathing.
Risk of Excessive Carbon Dioxide
Insufficient carbon dioxide removal may cause arterial acidemia.
For reducing the risk of rebreathing CO
2
, make sure that the leakage port is located as
near the patient interface as possible. This is even more important for treatments with
low pressure, as this reduces the flow through the leakage port.
WARNING!
Risk of Cross-Contamination
Patient circuits might get contaminated by exhaled gases. To avoid cross-contamination,
always use a properly cleaned or a new patient circuit when the Nippy 4 is to be used by
a new patient.
NOTE
For masks and accessories, always follow the manufacturer’s instructions.
2.5 Usage of Filters
WARNING!
Always use the ventilator with patient air inlet filters installed. Only use the ventilator
with accessories recommended by Breas Medical.
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 Nippy 4 to operate at higher temperatures
than intended.
When operating the Nippy 4, make sure that the air inlet and filters are not obstructed or
occluded.
