Immediate- casualties whose injuries are critical but who will require only minimal time or equipment to manage and who have good prognosis for survival.
|
|
|
What is an example of a Priority 1 casualty in a non-tactical environment?
|
a casualty with a compromised airway or massive external hemorrhage
|
|
|
What is Priority 2 for sorting in a non-tactical environment?

|
casualty with a long bone fracture
|
|
|
What is Priority 3 for sorting in a non-tactical environment?
|
Minor- "walking wounded" who have minor injuries that can wait for treatment or who may assist in litter bearing
|
|
|
What is Priority 4 for sorting in a non-tactical environment?

|
What is Hypovelmic Shock?
|
a loss of intravascular volume. Also known as hemorrhagic shock.
|
|
|
What is the average adult blood volume?
|
5-6 liters
|
|
|
How much blood loss creates a life-threatening condition?
|
1 liter or 25-40% of the person's total blood volume
|
|
|
This happens when the vascular container (blood vessels) dilate (enlarge) without proportional increase in fluid volume...
|
Distributive (Vasogenic) shock
|
|
|
Is caused by the failure of the nervous system to control the diameter of blood vessels...
|
Neurogenic shock
|
|
|
Is caused by the presence of severe infection which leads to vasodilation...
|
Septic shock
|
|
|
Is caused by stimulation of the vagus nerve produces bradycardia which can lead to fainting...
|
Psychogenic shock
|
|
|
Is caused by the heart failing to pump blood adequately to all vital parts of the body...
|
Cardiogenic shock
|
|
|
What are the 3 stages of shock?
|
compensated, decompensated, irreversible
|
|
|
What is compensated shock?
|
the blood pressure is maintained, but there is a narrowing of the pulse
|
|
|
What is decompensated shock?
|
the blood pressure is falling because the blood volume has dropped 15-25%. Signs and symptoms are much more obvious
|
|
|
What is irreversible shock?
|
shock has progressed to terminal stage. arterial blood pressure is abnormally low. does not normally result in recovery.
|
|
|
How many classifications of Hemorrhagic shock are there?
|
4
|
|
|
What is Class 1 Hemorrhagic shock?
|
body is able to compensate to maintain homeostasis
|
|
|
What is Class 2 Hemorrhagic shock?
|
circulating blood is reduced, compensatory mechanisms such as the sympathetic nervous system are able to maintain blood pressure and tissue perfusion
|
|
|
What is Class 3 Hemorrhagic shock?
|
unfavorable signs beging to appear. tachycardia, tachypnea, and confusion become obvious
|
|
|
What is Class 4 Hemorrhagic shock?
|
severe stage of shock! only minutes to live. survival depends on immediate control of hemorrhage
|
|
|
What relieves distressing pain and assists in preventing shock?
|
Morphine
|
|
|
Adult dose of morphine...
|
10-20mg which may be repeated in no less than 4 hours
|
|
|
When do not give morphine?
|
head injury, chest injury, wounds of airways, massive hemorrhage, respiratory impairment, evidence of severe shock, LOC
