Responding to Shock

Brooke and AnnmariePeriod 4

What is Shock?

A life-threatening condition occurs when the circulatory system fails to provide adequate oxygenated blood to all parts of the body

How Shock Occurs

An adequate amount of blood must be circulating in the body when this doesn’t happen, shock occurs.This shuts down all non-essential organs: the brain, heart and lungs

. Blood volume: the total amount of blood circulating within the body

Domino Effect

Injury causes severe bleedingHeart attempts to compensate for the disruption of blood flow by beating fasterAs blood volume drops, pulse weakensBlood vessels constrict in the arms, legs and skin, making the skin appear pale or ashen and feels cool

Due to stress, body perspires heavily and skin feels moist

Domino Effect (cont.)

Cells start to die in the arms and legsBrain then sends signal to return blood to arms and legsVital organs don’t receive enough bloodHeart tries to compensate by beating faster, more blood loss

Vital organs fail to function properlyDeath. 

Types of shock

Cardiogenic shockDistributive shockHypovolemic shockObstructive shock

Cardiogenic Shock

Failure of the heart to pump enough oxygenated bloodCan be too fast or too slow (ventricular tachycardia or ventricular fibrillation)Weak and ineffective contractions can be caused by damage from disease, trauma, poisoning, or respiratory problems

Distributive Shock

Abnormal dilation of the blood vesselsCan be caused by spinal cord, brain trauma, infection, or anaphylaxis

Hypovolemic Shock

Severe bleeding or loss of fluid from the bodyInefficient blood shock

Obstructive shock

Caused by an obstruction of blood flow

Other Reasons

Injury to the chestInsufficient oxygen enters the bloodstream

Signals

Usually caused by severe bleedingApprehension, anxiety, restlessness or irritabilityAltered level of consciousnessNausea/vomitingPale, ashen or grayish, cool, moist skin

Rapid breathingExcessive thirst

How to Care

Check and call firstOpen and clear the airwayControl external bleedingImmobilize injuries

Lie down the victim in a comfortable positionElevate feet to direct blood to essential organsKeep at normal body temperature, use a blanket or shading device if necessaryDo not give food or water (even if the victim shows excessive thirst)Calm and reassure the victimMonitor breathing and watch for changes in condition

Summary 

Shock is a life-threating condition that must be cared for immediately.

If not cared for immediately, the body will shut due to the Domino Effect.To recognize shock, first look for severe bleeding (most common signal) and see if the person is conscious. Then check the skin to see if it is turning ashen, pale or moist.Once you have checked and called, care by opening the airway, controlling external bleeding, immobilizing injuries, and laying the victim on his/her back in a comfortable position. If you can, elevate the legs, cover with a blanket/shading device, and calm/reassure. Remember to monitor breathing and not allow the victim to eat/drink.

Scenario

You are at Medieval Times with some friends watching a jousting tournament. Suddenly, you notice that one of the knights is accidently been impaled by his opponent’s

lance in the stomach area. He is on his back on the floor and has already lost a lot of blood. The staff clears the area of the horses and any sharp objects. When you check the man and he is fading in and out of consciousness. His skin is turning pale and ashen, and it seems very moist. His breathing is rapid and he seems to show signs of nausea. What do you do next?

Review

What is Shock?What is the Domino Effect?What are the 4 different types of shock?Name 2 signals of shock.Should give water to the victim if they have excessive thirst?
