pressure ulcer
B1CEFR level
40/100Rarity: uncommon
TechnicalRegister
A localised area of skin and underlying tissue damage caused by sustained pressure over a bony prominence.
The patient has developed a grade 2 pressure ulcer over the sacrum, so I've started two-hourly repositioning.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
