Mae'r system yn cynnwys lluniau enghreifftiol o niwed i'r croen i helpu staff i benderfynu ar hyd a lled y niwed y maent yn gweld ar eu cleifion i benderfynu'n fwy cywir ar y driniaeth orau, ac i atal niwed pellach. Mae'r arweiniad hwn yn seiliedig ar ganllawiau Nyrsys Hyfywedd Meinwe Cymru Gyfan, felly mae’n helpu i safoni llwybrau gofal.
The system includes illustrative examples of skin damage to help staff determine the extent of damage they are seeing in their patients to more accurately determine the best treatment, and to prevent further damage. The guidance is based on the All Wales Tissue Viability Nurse guidance thus supporting standardisation in the care pathway.
