Factors effecting the clotting process

Hypothermia acidosis hemodilution medications blood pressure

What is the lethal triad

Hypothermia - body loses oxygen and glucose to produce, leads to acidosis Acidosis: buildup of lactic acid from anaerobic metabolism causing coagulopathy Coagulopathy: inability to clot properly

When do you convert TQs

If evacuation to a definitive facility delayed (at least 2 hrs), you can reduce tissue damage Wound has been exposed and assessed Tactical situation allows Enough time before evacuations

Psychogenic shock

Increase stimulation of vagus nerve causes vasodilation and hypotension and leads to a dramatic fall in cardiac output. (syncope)

What are the two types of extracellular fluid

Interstitial fluid: surround tissue cells, includes cerebrospinal and synovial fluid Intravascular fluid: found in vessels, plasma of the blood

Do you use crystalloid in combat environment

It is no the fluid of choice for combat trauma casualties that require intravascular volume expansion due to hemorrhage

How does the ResQGARD work

It makes it a little harder to inhale and increase the negative pressure in the check. This pulls more blood back into the heart that results in increase filling of the heart will enhance cardiac output on subsequent cardiac contractions.

Moderate to sever pain, casualty is in hemorrhagic shock or respiratory distress

Ketamine 50mg IV/IM (30 min) or 30mg slow IV/IO (20 min) Stop giving when nystagmus develops Narcan 0.4mg iv/im if needed Zofran 4-8mg iv/im every 8 hrs as needed
