External Bleeding What to do: Check pulse below dsg site Radial Post Tib
External Bleeding What to do: If bleeding does not stop in 10 minutes: Press harder over a wider area for another 10 minutes.
External Bleeding What to do: If bleeding continues use pressure point above dsg site Pressure point: Brachial Femoral
brachial femoral
External Bleeding What NOT to do: Touch wound with bare hands
External Bleeding What NOT to do: Use direct pressure on an eye wound
External Bleeding What NOT to do: Remove a blood soaked bandage. (instead you should apply another on top.) Removing a blood soaked bandage is like removing a scab.

Shock Circulatory System Failure. 3 components in the Circulatory System: Pump: heart Pipes: vessels Fluid:blood
Shock Most seriously injured victims should automatically be treated for shock
Shock 3 Types: • Pump failure • Fluid Loss • Pipe Failure
Shock Pump failure: Failure of to pump sufficient blood. Ex: heart attack
Shock Fluid Loss: Loss of significant amount of fluid from body. Usually blood Could also be from fluid loss through: burns diarrhea vomiting
Shock Pipe Failure: Blood vessels enlarge and blood supply is not enough to fill them • Spinal cord damage • Drugs • Extreme fear, fright
Shock Pupils: dull or dilated Breathing, shallow, labored, rapid What to look for: Skin: pale, bluish, cold, clammy, profuse sweating Nausea, vomiting Pulse rapid, weak
Shock What to do: Lay down Cover with blanket Elevate legs (8-12 inches)
