When it comes to fault reporting you are right the "bed" is broken plus the assset number is all that is needed. But when it comes to planning equipment replacement or contracts you need to know exactly what you have.
I have been going through GMDN and they seem to have got rid of the code for a simple ripple mattress e.g. Huntleigh Nimbus etc. There are overlays and specialist mattresses like low air loss and fluidise. I went to report this as needing a new number and realised they would charge me 200euros for the privilege.
Am I right?
