Good Morning to you all, Another query to my colleagues on the mailbase please regarding our IL GEM 4000's;- Firstly, we are still having problems with cartridge failures on our 4000 analysers. Ours seem to be a mixture of initial CVP failures or a parameter "fixing" which never resolves (resulting in a crtridge having to be replaced), or various solution A//B errors. We have been told that no other sites have this many problems. I wondered if this were true, particularly as factors such as CVP failures could only be due to us installing the cartridge in correctly, which is actually difficult to do wrong. This means there is a consdierable down time when these analysers need to have their cartridge replaced, the data copied, and be re-calibrated. Secondly, we have recently had an issue on SCBU where some completely erroneous results were obtained on 3 separate occasions, but when the internal data for the analyser was reviewed, nothing was amiss, according to IL. I have wondered whether this might be due to the thick film technology that I understand is used on these sensors, and may be due to the presence of free haemoglobin? This could have arisen as a result of haemolysis while taking these (capillary) samples, but the if this was the case, I still am extremely concerned that result such as undetectable glucose, lactate, and inappropriate pO2 and pH levels could be reported and potentially acted upon. If any of you have any experiences or could pass this e-mail on to colleagues who may be involved, I would be most grateful.
