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.
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 Electric Shock
Do not use antistatic or electrically conductive hoses or tubing with the ventilator
breathing system. This could result in electrical shock.
WARNING!
Risk of Cross-Contamination
Patient circuits might get contaminated by exhaled gases. To avoid cross-contamina-
tion, always use a properly cleaned or a new patient circuit when the Vivo 2 is to be
used by a new patient.
NOTE
For masks and accessories, always follow the manufacturer’s instructions.
2.5 Filter Usage — Warnings and Precautions
WARNING!
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 2 to operate at higher temperatures
than intended.
When operating the Vivo 2, make sure that the air inlet and filters are not obstructed
or occluded.
