Shock and BLS Resuscitation Flashcards
what is shock or hypoperfusion?
Insufficient supply of oxygen and other nutrients to body cells resulting from inadequate circulation of blood
what is hypovolemic shock?
shock caused by the loss of blood or fluid from the intravascular space resulting in a low blood volume
what is distributive shock?
shock associated with a decrease in intravascular volume cause by massive systemic vasodilation and an increase in the capillary permeability
what is cardiogenic shock?
poor perfusion resulting from ineffective pump function of the heart
what is obstruction shock?
a poor perfusion state resulting from a condition that obstructs forward blood flow
What is hemorrhagic (hypovolemic) shock?
shock from the loss of whole blood from the intravascular space
what are the 5 functions of blood?
- transportation of gases (O2 and CO2)
- nutrition
- excretion
- protection
- regulation
perfusion
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
hypoperfusion
inability of the body to adequately circulate blood to the body’s cells to supply them with oxygen and nutrients. Also known as shock. A life threatening condition.
shock
inability of the body to adequately circulate blood to the body’s cells to supply them with oxygen and nutrients. Also known as hypoperfusion. A life-threatening condtion.
What are the steps to treat shock?
- maintain airway
- intimate oxygen therapy
- control external bleeding
- if local protocols call for it, contact medical direction and apply a pneumatic antishock garment (PASG)
- if no possibility of spinal injury, elevate legs 8-12 in.
- prevent loss of body heat by covering patient with blankets
- transport immediately
- consider meeting with ALS en route
- reassure patient
What are the 3 stages of shock?
- compensated shock
- decompensated shock
- irreversible shock
List some important indicators of internal bleeding
- injuries to the surface of the body
- bruising, swelling
- pain over vital organs
- painful, swollen, or deformed extremities
- bleeding from mouth, rectum, vagina, or any other orifice
- tender, rigid, or distended abdomen
- vomiting a coffee-ground-like substance or bright red vomitus
- dark, tarry stools or bright red color in stool
- signs and symptoms of shock
compensated shock
when the patient is developing shock but the body is still able to maintain perfusion
decompensated shock
the second stage of shock, which begins at the point when the body can no longer compensate for the low blood volume or lack of perfusion. Late signs as falling blood pressure develop.
