Ch 10: Shock Flashcards
Shock
A series of body responses to compensate for inadequate blood flow to the vital organs.
Types of Shock
Anaphylactic Cardiogenic Hypovolemic Neurogenic Psychogenic Respiratory Septic
Anaphylactic Shock
Life threatening allergic reaction to a substance
Cardiogenic Shock
Failure of the heart to effectively pump blood to all parts of the body
Hypovolemic Shock
Sever lack of blood and fluid in the body
Neurogenic Shock
Failure of the nervous system to control size of blood vessels, causing them to dilate.
Psychogenic Shock
Factors such as emotional stress cause blood to pool in the body in areas away from the brain because of vessels dilating.
Respiratory Shock
Failure of the lungs to transfer sufficient oxygen into the bloodstream
Septic Shock
Poisons caused by severe infection that cause blood vessels to dilate
How Shock Develops
The heart adjusts its speed and force of its contractions to meet the body’s changing demands for oxygen
Because the heart is beating faster, breathing must also speed up
The body is unable to adjust properly due to illness or injury and shock occurs
The body ensures adequate blood flow to the vital organs by shunting blood from the extremities, causing changes to the patients vitals
Signs and Symptoms of Shock
Early Stage:
- Pale, Cool, Moist Skin
- Tachypnea
- Weak Tachycardia
- Altered LOC
- Nausea
- Changes to Blood Pressure
Late Stage:
- Listlessness / Confusion
- Slow, shallow irregular breathing
- Hypotension
- Rapid, weak, irregular pulse
- Pale, cold, clammy skin
- Dilated pupils
Care for Shock
- Assess patient ABCD’s and provide care for any vital emergencies and bleeding
- Provide care for specific conditions
- Patient rest comfortably
- Maintain normal body temperature
- Administer Oxygen
- Keep patient’s stomach empty
- Obtain advanced medical care
- Provide ongoing survey and care
