IEC 60601-1 and IEC 62353 must be observed specifically for medical devices with
an electrical connection. According to these directives, these devices must only be
repaired by the manufacturer or an entity explicitly authorized by the manufacturer for
this purpose.
Check that no condensation accumulates near the Y piece of the inspiration tube
which could leak into the flow sensor.
Make sure that there are no water droplets in the pressure measurement lines.
After using the special alarm suppression state, make sure that the alarm is reactivated
before leaving the patient.
FRITZ STEPHAN GMBH recommends that the ventilator is not operated with a low
battery (capacity <10%) because the device will switch off immediately in the event
of a power failure.
Incorrectly selected trigger thresholds and large leaks may cause auto-triggering! In
this case, the trigger threshold has to be manually adjusted.
When adding system components or sub-assemblies to the ventilation system of the
ventilator, the pressure gradient across the ventilation system, measured at the patient
connection port, may negatively affect the performance data of the ventilator.
