Hi Richard,
Well ,one of our tech guys here has found one of the problems,(he's still awaiting the nobel prize for it),he has found that some of the giving sets in certain batches has a coating on the outside of the tubing, because they use ultrasound to detect 'air in line',this coating is stopping the ultrasound penetrating through and causing false alarms i.e. 'air in line'
Company does know,but have heard nothing from them as such at the moment, its something to do with the way in which they steralize the sets before use!
Hi Liz
no problem i have a meeting this Friday i will let you know.
would still like to hear from anybody experiencing the same problem or not.
