AB Pressure  ulcers  are  caused  by  pressure  applied  to  susceptible  tissues.  Tissue  susceptibility  may  be  increased  in  the  presence  of  maceration  and  by  friction  and  shear  forces.Comorbid  conditions,  especially  immobility  and  decreased  tissue  perfusion,  increase  the  risk  of  pressure  ulcers.Most  pressure  ulcers  develop  over  bony  prominences,  most  commonly  the  sacrum,  heels,  and  trochanteric  areas.Most  pressure  ulcers  develop  in  acute  hospitals;  the  risk  is  greatest  in  orthopedic  and  intensive  care  unit  patients.Pressure  ulcers  can  be  stage  I  (blanchable  hyperemia),  stage  II  (extension  of  the  ulcer  through  the  epidermis),  stage  III  (full-thickness  skin  loss  with  damage  or  necrosis  of  subcutaneous  tissue),  or  stage  IV  (full-thickness  wounds  with  extensive  destruction,  tissue  necrosis,  or  damage  to  muscle,  bone,  or  supporting  structures).Pressure  ulcers  do  not  necessarily  progress  from  stage  I  through  stage  IV.
