We recently got a new freezer for the Blood Bank. I am performing my first validation. I am comparing the NIST against the digital display as well as the chart and our own, seperate thermometer. I cannot find any documentation to support how much difference is acceptable between the NIST and the digital read/our thermometer/ etc. Some places I have read say 0.5 degrees which seems very tight to me. Another facility I work for uses 1.0 degree difference which seems more acceptable and able to obtain but I have not found any supporting documentation anywhere!
Can someone help me? When validating, what difference is acceptable between the NIST and the other thermometers, be it the probes in the unit or your own internal thermometers?
Need some guidance on validation of blood warmers. Recently our clinical engineering bought 24 new blood warmers, same model and brand of what we have already used and validated. We have just recently validated 6 of the 24 new ones with running blood through them and taking whole blood potassium levels at hourly intervals.
The question we cannot agree on is do we need to validate every single blood warmer or is the 6 that we have done a sufficient sampling to be able to make a blanket statement that the warmers are ok for patient use. Anyone have any evidence based answers to this? At this point I'll take just some good advice! Thanks in advance.
We have just received the OrthoWorkstation to replace our ID-MTS. What kind of validation did you use? How many positive and negatives for parallel testing? Just trying to get an idea before I get started. The manual has no recommendations as to how to validate. Also, what kind of thermometers are you using for it? I know we are going to have to get a new one to fit inside one of the gel cards.
Has anyone installed a new blood bank refrigerator recently? I know we need to do IQ, OQ, and PQ. Does anyone have plans that they have used successfully that you would be willing to share. Did you perform temperature mapping or have it performed by vendor or third party?
