EC Chp 25 Bleeding and Shock Flashcards
Understanding Bleeding and Shock
Perfusion (adequate circulation of blood)
the supply of oxygen to and removal of wastes from the body’s cells and tissues as a result of the flow of blood through the capillaries
Hypoperfusion (Shock)
the body’s inability to adequately circulate blood to the body’s cells to supply them with oxygen and nutrients
Blood has several functions what are they?
Transportation of gases
Nutrition circulation to other body cells from intestines
Excretion of wastes
Protection with white blood cells and antiboies
Regulation
Heart, blood vessels and blood are
The 3 main components of the circulatory system
hemorrhage is also known as
severe bleeding
external bleeding is bleeding that happens….
outside of the body visible on the surface of the skin
Arterial bleeding is an example of external bleeding and signs of it are
spurting blood
pulsating flow
bright red
Venous Bleeding is another external bleeding. what Types of signs would you see?
steady, slower flow then arterial and darker red color
Junctional Hemorrhage happens in areas where veins and arteries tend to be less well protected. where are these places?
occurs where the appendages of the body connect to the trunk. Ex: neck, both armpits and sides of groin
when is capillary bleeding at risk of high infection
when the it occurs over large areas
Bleeding can also be accelerated if patients have underlying conditions and take medications for them. these meds are what and used for what?
blood thinners and used for patients with history of stroke or heart problems. Ex. asprin, warfarin, clopidogrel, pradaxa
We also know that hypothermia has what affect on the body
it affects the body’s ability to clot
First step in most cased in bleeding control is to
COMPRESS the wound with DIRECT PRESSURE
with a pressure dressing using several gauze pads and roller bandage you must ensure you…
create enough pressure to control the bleeding
What must you always do after controlling bleeding for an exteremity using a pressure dressing
check for a distal pulse to make sure the dressing has not been applied too tightly
Do NOT use the elevating technique in an injury when…
you suspect a possible musculoskeletal injury
Hemostatic agents are
products as powders, dressings, gauze or bandages designed to stop bleeding.
For large cavity been formed from trauma direct pressure is not typically effective. You can address the issue by
filling the cavity with dressings or unrolled bandages and hemostatic agent as its for wound packing and an agent
When Obvious bleeding and rapid soaking through of dressing are happening even with direct pressure what should you do?
apply a tourniquet! that closes off all blood flow to and from the extremity
Tourniquets are only use on extremity injuries. Where should you place it approximately
approximately 2 inches above the bleeding wound
If a tourniquet is not available you can use…
a cravat, or improvised materials, but should be 2 inches wide and several layers thick.
