MEDUVENT Standard EN 11
2 Safety
Hazardous therapy due to leaks during ventilation!
The measured MVi value indicates the volume the device is
administering to the patient. In the event of leaks during
ventilation, the measured MVi value will not match the tidal
volume actually administered. If this is not observed, the patient
might suffer serious or life-threatening injury.
Check that the mask or tracheal tube is correctly positioned.
Do not use the measured MVi value as an adequate means of
assessing ventilation.
Use external monitoring (etCO
2
, SpO
2
or expiratory volume
measurement).
Risk of infection resulting from failure to use hygiene filter!
If the device is used without a hygiene filter in a contaminated
environment, it might draw in contaminated ambient air. This
might cause the patient and the user serious or life-threatening
injury.
Always use a hygiene filter when operating the device in a
contaminated environment.
Reduced ventilation performance resulting from increased
device input resistance as a result of using the device in a very
dusty atmosphere!
If the device is operated in a very dusty atmosphere, it might draw
in dust and dirt from the ambient air, which might get into the
patient's lungs. Ventilation performance might also be reduced by
increased device input resistance. This can cause serious or life-
threatening injury to the patient, and damage the device.
Only operate the device with a hygiene filter.
Replace the hygiene filter after operating the device in a very
dusty atmosphere.
