Decreased vital organ function due to decreased oxygenation. Usually due to a problem with blood and bloodflow.

oxygen delivery to cells depends on
Oxygen delivery to cells depends on:
  • Adequate blood volume
  • Effective heart
  • Good blood vessel function
mechanisms of shock
Mechanisms of Shock
  • Hypovolemic – Low volume of body fluids
  • Cardiogenic – pump failure
  • Low Resistance (vasogenic) – blood vessels are excessively dilated

- Psychogenic shock

- Anaphylactic shock

signs symptoms of shock
Change in LOC

Rapid, weak pulse

Rapid, shallow breathing

Cool,clammy skin



N & V

Dilated, glassy eyes

Signs & Symptoms of Shock

-crimson and flows

  • Capillary

-red (not bright but not crimson)

and ebbs

control of bleeding
Control of Bleeding
  • STEP I
    • Direct Pressure
      • Also use ice and elevation if possible

Control of Bleeding
  • Step II
    • Keep doing step I
    • Apply a tourniquet
  • Pinch nostrils (direct pressure)
  • Have victim sit up with head forward
  • Apply an ice pack to either the bridge of the nose or between the upper lip and bottom of nose

Ice pack to area

Treat shock

Signs and symptoms

Pain and tenderness



Signs of shock

Internal Bleeding


Closed or Open

closed wounds
Closed Wounds
  • Contusion—skin is red
  • Bruise- black and blue
  • Hematoma- raised bruise


  • Wash wound
  • Apply ice pack
open wounds

Open Wounds

Infection as well as bleeding

abrasion treatment
Abrasion Treatment
  • Clean wound
  • Apply dressing and bandage
  • Watch for infection
incision treatment
Incision Treatment
  • Control bleeding
  • Clean wound (gently!)
  • Apply dressing
  • Watch for infection
  • May need physician evaluation
laceration treatment
Laceration Treatment
  • Same as incision
puncture wound treatment
Puncture Wound Treatment
  • Stabilize impaled or penetrating object (exception for the cheek)
  • Get medical evaluation
  • Watch for infection (likely – why?)
avulsion treatment
Avulsion Treatment
  • Control bleeding
  • Clean and dress
  • Seek physician evaluation
  • Watch for infection
  • If complete avulsion (amputation), take avulsed tissue to physician for reattachment!
care of the avulsed tissue
Care of the avulsed tissue
  • Wrap tissue in clean cloth
  • Put wrapped tissue in plastic bag
  • Put plastic bag in a bag of ice
