what percentage of drop in body heat can cause blood clotting factors to lower and allow patient to bleed faster | 1% |
what is a hemostatic agent used for? | to help the blood to form a clot to help stop bleeding |

venous bleeding | dark red, flows slowly, easier to manage, if big enough it could pour out. |
capillary bleeding | dark red, oozes slowly/steadily |
