Roedd y gwaith o gynllunio'r uned wedi cael ei lywio gan anghenion clinigol. Mae wedi cael ei chynllunio felly i fodloni anghenion penodol oddeutu 20 – 25 o gleifion sydd ag anghenion cymhleth iawn. Cleifion yw’r rhain y mae angen dialysis rheolaidd arnynt, yn ogystal â chymorth allweddol amlddisbyblaethol gan y llu o wahanol arbenigwyr sy'n gweithio yn yr Ysbyty Athrofaol.
The new design has been clinically led to produce a unit designed to meet the specific demands of about 20 – 25 highly complex patients who not only require regular dialysis, but who also need key multidisciplinary input from the many specialties that are based within UHW.
