debride

harbors bacteria

what needs to be addressed first with bacteria control?

high bacteria levels

antimicrobials

why do dead spaces need to be packed?

they promote build-up and bacterial growth

what does increased cellular activity during wound healing create?

intensified metabolic demand fro nutrients

a dry cell is a ...

DEAD cell

what does arterial compromise cause?

decreased oxygen to wound bed
