Restarting an Infusion following an Air-in-Line Alarm
w
The Pump may be restarted by opening the door, assessing and removing any air from the tubing guide area and in
the infusion set on the patient side of the Pump (if required) according to hospital policy . Close the door and cancel
the air-in-line alarm . Restarting the infusion will reactivate the air-in-line system and will alarm if the preset air-in-
line limit is exceeded .
Air ingress and bubble formation within the administration set is a known risk of infusion therapy .
This risk is multiplied when (a) multiple infusions are being administered simultaneously, and (b) where drugs or fluids which are known
to have a tendency to degas, are being infused, with a potential consequence of an increase of air accumulation within a patient’s
circulation .
At an elevated risk of suffering potential consequences of air ingress are patient groups with Atrial Septal Defects . It is therefore
recommended for this group that in addition to the existing air in line detection mechanism of the Pump, an air venting filter is used on
the infusion set .
We advise you to also consider using an air venting filter:
a) for other patient groups known to be at an elevated risk of suffering potential consequences of air ingress, such as neonates and
b) for situations presenting a multiplied risk of air ingress, such as can be found in critical care areas (multiple parallel infusions) or
where drugs or fluids which are known to have a tendency to de-gas are being infused .
Where air venting filters cannot be used consider using anti siphon valves .
