Term
arterial bleeding
Definition
bleeding from an artery, which is characterized by bright red blood and as rapid, profuse, and difficult to control. spurting blood
Term
capillary bleeding
Definition
bleeding from capillaries, which is characterized by slow, oozing flow of blood.
Term
cardiogenic shock
Definition
shock, or lack of perfusion, brought on not by blood loss, but bu inadequate pumping action of the heart. it is often the result of a heart attack or congestive heart failure.
Term
compensated shock
Definition
when the patient is developing shock but the body is still able to maintain perfusion
Term
decompensated shock
Definition
occurs when the bod can no longer compensate for low blood volume or lack of perfusion. Late signs such as decreasing blood pressure become evident. 
Term
hypoperfusion
Definition
inability of the body to adequately circulate blood to the bodys cells to supply them with oxygen and nutrients. 
Term
hypovolemic shock
Definition
shock resulting from blood loss. 
Term
irreversible shock
Definition
when the body has lost the battle to maintain perfusion to vital organs. even if adequate vital signs return, the patient my die days later due to organ failure.
Term
neurogenic shock
Definition
hypoperfusion due to nerve paralysis resulting in the dialation of blood vessels that increase the volume of the circulatory system beyond the point where it can be filled.
Term
perfusion
Definition
the supply of oxygen to and removal of wastes from the cells and tissues of the body as a result of the flow of blood through the capillaries 
Term
pressure dressing
Definition
a bulky dressing held in position with a tightly wrapped bandage to apply pressure to help control bleeding.
Term
shock
Definition
the inability of the body to adequately circulate blood to the bodys cells to supply them with oxygen and nutrients. a life threatening condition. 
Term
tourniquet
Definition
a device used for bleeding control that constricts all blood flow to and for the extremity 
Term
venous bleeding
Definition
bleeding from a vein, which is characterized by dark red or maroon blood and as a steady flow, easy to control. 
Term
hemorrhage 
Definition
bleeding internal or external
Term
methods of emergency care of external bleeding
Definition

1.Direct pressure

-BSI

-use a sterile dressing

-pressure bandage 

-you may only remove a dressing once it is placed and the bleeding does not stop

-id bleeding continues add more dressings

-after bleeding has stopped maintain pressure with a bandage

2. Elevation

-gravity is our friend

-do not elevate a broken extremity.

-if there is no blood there to bleed, it wont bleed.

3. pressure points

-brachial and femoral

4. splinting.

-bleeding is associated with broken bones

-broken bones cut muscles  and other tissues.

5. air splints.

6. MAST-PASG

7. oxygen 

8. tourniquet

-only use if necessary.

-if used always use a wide flat material.

-never loosen a tourniquet

-never cover a tourniquet

-write TK in a visible area.

9. IV of NS or LRS palpate to b/p of 90 systolic 

Term
steps in emergency care of signs and symptoms of internal bleeding
Definition

1. maintain the ABC's and provide support as needed.

2. administer high-concentration oxygen by nonrebreather mask, if oxygen administration has not already begun.

3. control any external bleeding. If you suspect internal bleeding in an injured extremity, apply an appropriate splint. 

4. provide prompt transport to an appropriate medical facility.

Term
treating hypovolemia shock
Definition

"the goal is to decrease the body's demand for oxygen and to increase the supply of oxygen"

-keep the patient still

-maintain an open airway

-restore breathing and circulation as necessary

-control bleeding

-administer high concentration oxygen.

-splint fractures as necessary 

-prevent loss of body heat.

-do not give anything to eat or drink

-loosen all restrictive clothing.

-elevate legs

-IV of NS or LRS to titrate to BP

Term
how much blood and how much has to be lost for shock to occur
Definition

average adult has 6 liters of blood, the loss of 10%=shock

 

child has 3 liters of blood, the loss of 200-300 mL= shock

 

infant has 200-300 mL of blood, the loss of less that 30 mL=shock

Term
occulsive
Definition
airtight. 
Term
clotting/coagulation
Definition

--3 step process

-Vascular phase

=vasoconstriction

-platelet phase

=tunica intima damaged

*turbulant blood flow

*frictional damage to 

 platelets.

-coagulation phase

=release of enzymes 

*fibrin release.

 

-normal coagulation=7 to 10 min

 

Term
factors that affect clotting 
Definition

-movement of the wound site

-aggressive fluid therapy

-low body temperature

-medications that thin blood

Term
signs of internal bleeding
Definition

-signs of shock that are unexplainable.

-fractures

-mechanism

-ecchymossis- bruising

-hematomas

-hemoptysis- vomitting blood

-esophageal varices

-blood coming out of other orifices

-tenderness.

-injuries to the surface of the body, which could indicate underlying injuries.

-bruising, swelling or pain over vital organs.

-painful, swollen or deformed extremities.

-a tender, rigid or distended abdomen.

 

Term
when should you consider bleeding serious?
Definition

-the patient has poor general appearance.

-associated with a significant mechanism.

-assessment reveals signs and symptoms of shock. 

-you note a significant amount of blood loss.

-you cannot control the bleeding.

Term
care for nosebleeds
Definition

nosebleeds=epistaxis

1. BSI

2. lean forward with the head tilted forward. 

3. pinch the fleshy part of the nostrils together for at least 15 seconds(preferred) 

-place a 4x4 under the upper lip

-apply ice over the nose

4. Keep the patient calm and quiet.

Term
stages of shock
Definition

-compensated shock- the patient may have an altered LOC, anxiety or restlessness, pale clammy and cool skin, rapid, thready and weak pulse, increased breathing rate, nausea and vomiting, thirst, pallor with cyanosis about the lips and an impending sense of doom.

-decompensated shock

the patient may present all the signs of compensated shock plus a falling BP systolic of 90 or lower, labored irregular breathing, ashen mottled or cyanotic skin, thready or absent peripheral pulses, dull eyes, dilated pupils, no urine output, and low LOC

-irreversible shock

this is a terminal stage. any treatment at this point will not save the patient. There respiratory rate is dropping, low to no LOC. patients may "recover" but it is temporary this is the body's last attempt at homeostasis.

Term
treating cardiogenic shock
Definition

-there is usually only chest pain associated with this type of shock.

-normal treatments may be harmful.

-if chest pain->nitro, ASA

-high flow 02

-IV of NS TKO

-calm reassurance.

Term
Treating neurogenic shock
Definition

-supportive methods

-immobilization

-high flow 02

-airway management 

-conserve body heat

 

 

Term

treating metabolic shock

 

Definition

-secure airway

-appropriate oxygen

-assist in ventilations if necessary

-determine illness

Term
treating anaphylactic shock
Definition

-supply respiratory rate

-assist in ventilations as necessary

-determine cause

-administration of epinephrine 

-administer 02

-transport

-IV of NS TKO

Term
treating psychogenic shock
Definition

-determine the duration of unconsciousness

-record V/S and mental status

-suspect head injury if the patient id confused or slow to regain consciousness. 

-transport

Term
Treating septic shock
Definition

-administer 02 en route 

-transport

-airway management and ventilation support

-keep warm

 

Term

to keep open

Term

IV term

keep vein open

Term

LRS

 

Definition

lactated ringers solution

you administer this to patients with blood loss. 

Term
NSS
Definition

normal saline solution

used to replace plasma.

Term
sympathetic nervous system
Definition

associated with the autonomic nervous system.

 

-releases catecholamines 

-promotes a "fight or flight" response.

-diverts blood flow away from the GI and skin via vasoconstriction. 

-blood flow to skeletal muscles, the lung is not only maintained but enhanced by as much as 1200%

-dilates the bronchioles, which allows for greater alveolar oxygen exchange.

-increases heart rate. 

-dilates pupils and relaxes lens allowing more light to enter the eyes.

Term
parasympathetic nervous system
Definition

associated with the autonomic nervous system.

 

-rest and digest.
