SI Question - dark blood

Pomegranate · 01-05-2008, 04:13 AM

Hi, sorry this isn't urgent. I have got the bleeding to stop. Just wondering, a couple of times now when cutting I have cut and then dark blood has sort of started pumping/flowing sort of out of the wound. I managed to get it to stop within about 10 minutes, just wondering what this was. It was bleeding as normal then when I went and cut over it again, it started suddenly pumping this dark blood. Just curious, thanks.

Hi hun..

Sounds like you hit a small vein..

dark blood steadily flowing = venous blood.
bright red blood spurting in time with heartbeat=arterial blood.

Take care hun and try to stay safe...

More likely to be a venule(little vein branch) as Arterioles (little artery)still pump blood plus this will be bright red where as venules have a constant flow of darker coloured blood.
