Q:l ifl pressurel isl relievedl andl blowl flowl returns,l thel skinl turnsl red.l Thel effectl ofl thel rednessl isl vaso____l alsol knownl asl hyperemia
*l youl assessl hyperemial byl pressingl al fingerl overl thel affectedl area.l Ifl itl blanchesl (lighter)l andl erythemal returnsl whenl youl removel yourl finger,l blanchel hyperemial hasl occured
Answer:
dilationl (bloodl vessell expansion)
Q:l non-blanchablel erythema
Answer:
Stagel 1l Pressurel Injury:l
thel erythematousl areal doesl notl blanchl (orl becomel lighter)
Q:l Pressurel Duration
Answer:
Lowl pressurel overl prolongedl periodl ofl timel &/orl Highl pressurel overl al shortl periodl ofl time -pressuresl occurl quicklyl (1-2hrs)
Clinicall implicationsl ofl pressurel durationl includel evaluatingl thel amountl ofl pressurel (checkingl thel skinl forl non-blanchingl hyperemia)l andl determiningl thel amountl ofl timel thatl al patientl toleratesl pressurel (checkingl tol bel surel afterl relievingl pressurel thatl thel affectedl areal blanches)
Q:l Tissuel Tolerance
Answer:
thel abilityl ofl thel tissuel tol endurel pressurel dependsl onl thel integrityl ofl thel tissuel andl thel supportingl structures
