And in this area, there is a lot of inflammation.

So our body is trying to respond to that central area.

It knows that there's something wrong here.

But there's very low levels of blood flow.

There's a lot less perfusion in this zone because of damage that was sustained and our body's response of kind of clamping down to try and protect that area.

Okay.

Which has the effect that if that area is not addressed, then the damage from the burn can actually extend out over the next 24 to 48 hours.

Okay.

How can it do that?

Because that area, that zone of stasis, is not getting enough blood flow.

If that blood flow is not restored to that area, then that area is also going to die because of a lack of blood flow.

Okay.

Does that kind of make sense?

I think so, yeah.

And then outside of that zone is called the zone of hyperemia.

And this is non-damaged tissue where perfusion hasn't been affected.

And this is all like viable tissue, essentially.

So in the first 48 hours, it's important to be able to find those areas and see how much tissue can be salvaged, especially, and I'm talking really in the case of deep partial thickness.

So like those more severe second degree burns or third degree or full thickness burns, right?

Okay.
