the reason for the alarms is that the b-braun pumps accumilated air alarm counts bubbles down to 0.1 micro litres all other manufactuers i contacted state they count bubbles down to 0.45 micro litres. when i was shown the eu requirements for air it states all bubbles less than 0.45 mico litres can be ignored. when i mentioned counting bubbles down to 0.1 microlitres they all said this would cause nonsense alarms. our cancer department got so frustrated with the brauns they chucked them out and went back to baxter.
