Causes of trauma arrest?

Central
Blood Loss
Tamponade
Hypoxia
Hypothermia
Pneumothroax
Aortic Rupture
Electrocution
Drowning

1

What type of trauma arrest has a lower survival rate? Blunt or Penetrating?

Blunt

2

Define electrical phase of cardiac arrest.

Time: beginning of arrest and ending 3-4 minutes post arrest.

Disordered electrical conduction in heart; IMMEDIATE DEFIBRILLATION

3

Define metabolic phase of cardiac arrest.

Time: beginning 10 minutes after onset of cardiac arrest.

Survival low

Failure of sodium-potassium pump

GI loss

Severe acidosis

Myocardial ischemia, infarction

4

Causes of young "healthy" arrest.

Brugada syndrome

Long QT Syndrome

Hypertrophic Cardiomyopathy

Commotio Cordis

"Trauma"

5

Initial response to cardiac arrest.

BSI SCENE SAFE

Assesment:
Unresponsive, apneic, pulseless, peripheral pulses absent

Question events prior to arrest

Establish how long patient has been down

6

What are points to be remembered about post arrest?

Do not be concerned if post-arrest patient does not show any signs of response

Approach problems one at a time

Induced therapeutic hypothermia

7

What are some consideration for field termination of CPR?

Rigor mortis, fixed dependent lividity, decapitation, decomposition, incineration are all situations in which you should withhold resuscitation.

Withhold resuscitation efforts if patients have a out-of-hospital advance directive

8

What are causes for PEA?

Hypovolemia

Cardiac tamponade

Tension pneumothorax

Hypoxemia

Acidosis

Massive pulmonary embolism

Ventricular wall rupture

9

What are the reversible causes H's?

Hypovolemia, hypoxia, hydrogen ion (acidosis), Hyper and hypokalemia, Hypoglycemia, hypothermia

10

What are reversible causes T's?

Toxins, Tamponade (cardiac), Tension pneumothorax, Thrombosis (coronary and pulmonary) and trauma

11

Why is a patient in cardiac arrhythmia and normal SPO2 ranges (93 - 100%) not in need of oxygen?

Hyperoxygenated patient will have free radical release
