Renal units in Kent are now counting the benefit from the installation of heat exchangers to dialysis machines.
The project to retro-fit heat exchangers in dialysis machines at various renal units around East Kent Hospitals University Foundation Trust is nearing completion. Funding for 52 machines was secured in a ‘Dragons Den’ event back in June. Innovative ideas were presented to the Trust during the evening and successful schemes were awarded funding there and then. The pitch requested a capital outlay of £11,600 with a return expected within four years. It is estimated that the resulting total carbon saving annually should be in the order of 14 Tonnes CO2e. The heat exchangers were delivered by BBraun in August and the installation process started immediately.
Machines in the renal unit at William Harvey Hospital in Ashford were all modified by the end of August. Along with the existing stock of HDF (Haemodiafiltration) specification machines, with factory fitted heat exchangers, every machine in this unit can benefit from the device. Furthermore, the unit is now being used to evaluate their effectiveness. Monthly electrical meter readings are now monitored and compared with previous readings. Comparisons made over a six or twelve month period will be more representative, but the initial results from the first month or two are eagerly awaited.
