Clotting = Positive feedback 1. A blood vessel Breaks 2. A Platelet plug forms 2. Serotonin is released and a vascular spam occurs, slowing blood to the area 3. Platelets also release Serotonin and other chemicals attracting other Platelets to the LOG Jam 3. Tissue secrete TF (Tissue Factor) interacting with PF3 a coat on platelets and the “Clotting Cascade” is set off. 4. The “Clotting Cascade” = Prothrombin  Thrombin + Fibrinogen = Fibrin + RBC’s forming a Clot. The Plug is then replaced by the The Clot Or as I like to call it “All hell breaks loose!”

So lets see that Simple: A Vessel Breaks
Vascular spasm occurs: Serotonin released blood flow slowed
TF+PF3 = Clotting Cascade
Prothrombin  Thrombin
Thrombin + Fibrinogen = Fibrin + RBC = Clot
Hour later the Clot squeezes and pulls the blood vessel together
Platelet plug forms (Gives off Serotonin + other attracting chemicals for more Platelets)
The Plug is replaced by “The Clot” (Fibrin + RBC’s)
Bleeding has Stopped If this were a paper cut…

Fibrin + RBC’s = Clot

2 Kinds of Unwanted Clots Thrombus: A blood clot in a unbroken blood vessel. From the Greek thrombos meaning a lump or clump, or a curd or clot of milk. Real Life: Snake bite (this is G Rated) Nice Shorts! Probably why the snake bit you in the 1 st place!!

2 Kinds of Unwanted Clots Embolus: Clot that travels through the bloodstream, lodges in a blood vessel and blocks it. Killing off surrounding tissue. This a Stroke There is also a Pulmonary Embolism = Heart Attack

Ways of stopping the Bleeding
A Band Aid and kiss ?
Raise the area above the heart. If not then..
Put a gauze on it, if the blood soaks through don’t sweat it put another on it.
Let it sit for 30 mins if it doesn’t stop its now serious.
If its seriously deep and you got a few things you can do.
Lets talk about those options shall we?

Control the Bleeding
Clotting Agents = QuickClot , HemCon and Celox . (pick em up in catalog)
Tourniquet = Released every 10-15 mins
Not so bad you can use
Crazy Glue (seriously)
Butterfly tape (Till you get stitches)
Stitches/Sutures …
YES!!! LETS LEARN ABOUT THAT!!!!
