We have permanent OR coolers with continuous temp monitoring (temptrak). Units are sent to and returned from the OR via pneumatic tubes. We are taking the temps of returned units (tempcheck) and discard units over 10 degrees. Way too many units are recording temps slightly over 10 and being wasted.I believe that the whole transporting process (taking units out of the coolers, placing in the tubes, traveling thru the tube system, removal of units from pneumatic tube and finally taking the temps) is causing otherwise fine units to go over 10 degrees during the transporting process. Is it necessary to check the temps of returned units that have been stored in continuously monitored coolers? It seems so silly, as we accept units back from the regular floors within 30 minutes of issue without any refrigeration or temperature checking.
