Cleaning the Flow Head
Not applicable to later models using a moulded flow head/outlet pipe.
Depending on the age of the NIPPY+ it may be fitted with a flow head which
uses a stainless steel gauze to restrict the airflow slightly and cause a flow of
air through the flow transducer. If dirt or dust is allowed to build up on the
gauze, the flow calibration may be affected.
Inspect the gauze type of flow head when servicing the NIPPY+.
Remove the flow head from the ventilator before cleaning.
Any contaminates should be cleaned off very carefully . Ultrasonic cleaning is
preferred but if this is not available the gauze may be cleaned using a small
soft bristled brush dipped in isopropyl alcohol. Allow to dry before use.
Always check the flow calibration after cleaning.
