Bleeding, Shock, and soft-tissue injuries, Hemostatic agents (Chapter 14) Flashcards
Standard Precautions
- Wear gloves
- If appropriate, wear a surgical mask and eye protection
Shock
defined as failure of the circulatory system
Circulatory failure has many possible causes, but three primary causes are:
- Pump Failure
- Pipe Failure
- Fluid Loss
Pump Failure
- Cardiogenic Shock occurs if the heart cannot pump enough blood to supply the needs of the body
Results from a heart attack
Pipe failure
- caused by the expansion, constriction and ultimately the breakage of the vessel
-
Anaphylactic shock
- Rapid drop in blood pressure
- Spinal shock
-
Anaphylactic shock
Fluid Loss
- caused by excessive bleeding (hemorrhage) or loss of other body fluids
-
How do you know someone is bleeding?
- You can see, feel and smell it
-
How do you know someone is bleeding?
- Internal bleeding:
- Bruising
- Swelling
- Rigidity in the affected area
- Severe pain in the immediate area
An average adult has about _____ pints ( Liters) of blood circulating in the system
Loss of ______ or more pints can lead to shock
Someone experiencing Shocks feels ________
12pints (5.7 liters)
2 or more pints = shock
“impending doom”
General Treatment for ‘Shock’:
- Lay the person flat on his or her back on horizontal surface
- Control major bleeding
- Maintain the patients ABC’s
- Treat the causes of shock if possible
Maintain the patient’s body temperature
Controlling External Blood Loss:
Capillary Bleeding:
- Blood ooze outs
- most common type of blood loss
Venous Bleeding:
- Steady flow
- Direct pressure for at least 5 minutes
- second common type of blood type
Arterial Bleeding:
- Spurts or surges with each heartbeat
- Exert direct pressure and maintain pressure until EMS arrives
- Most serious type of bleeding
Tourniquets
indicated only in situations where extremity bleeding cannot be controlled by direct pressure or elevation
- Brachial, Femoral
- After applying, write TK and the time of application on the patient’s forehead (ex. TK: TIME)
- Rule of thumb: check for distal pulse (furthest away from tourniquet)
- *2-3 inches above the bleeding site*
- As tight as 3 fingers
Closed Wounds:
the only closed wound is the bruise (contusion)
Open Wounds:
- Abrasion —> scrape
- Puncture —> sharp object penetrates the skin
- Laceration —> cut
Avulsions / amputations —> tearing away of body tissue / entire body part is torn away
Dressing and Bandaging Wounds
- Control bleeding
- Prevent further contamination
- Immobilize the injured part
- Prevent movement of impaled objects
Dressing
VS
Bandaging
Dressing - an object placed directly on the wound (never remove dressing)
Bandaging- used to hold the dressing in place
Burn Depth:
superficial burns
partial-thickness burns
Full-Thickness burns
1st degree burns
2nd degree burns
3rd degree burns
Thermal Burns caused by _____
Respiratory Burns are located in any part of the _____
Chemical Burns are to be flush with ____ for at least ____ min
Electrical Burns enters _____ at one point, travels through and exits at the point of ________
caused by heat
a burn to any part of the airway
- strong substances
- Brush away any dry chemical
- Flush with water for at least 10 minutes
an electrical current enters the body at one point, travels through the body tissues and organs, and exits at the point of ground contact
QuikClot Combat Gauze LE
causes rapid localized coagulation and formation of a stable blood clot in a variety of wounds
- Up to 3 minutes of continuous pressure
