Flashcards in Post Arrest Care/PEA Deck (12):
Causes of trauma arrest?
What type of trauma arrest has a lower survival rate? Blunt or Penetrating?
Define electrical phase of cardiac arrest.
Time: beginning of arrest and ending 3-4 minutes post arrest.
Disordered electrical conduction in heart; IMMEDIATE DEFIBRILLATION
Define metabolic phase of cardiac arrest.
Time: beginning 10 minutes after onset of cardiac arrest.
Failure of sodium-potassium pump
Myocardial ischemia, infarction
Causes of young "healthy" arrest.
Long QT Syndrome
Initial response to cardiac arrest.
BSI SCENE SAFE
Unresponsive, apneic, pulseless, peripheral pulses absent
Question events prior to arrest
Establish how long patient has been down
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
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
What are causes for PEA?
Massive pulmonary embolism
Ventricular wall rupture
What are the reversible causes H's?
Hypovolemia, hypoxia, hydrogen ion (acidosis), Hyper and hypokalemia, Hypoglycemia, hypothermia
What are reversible causes T's?
Toxins, Tamponade (cardiac), Tension pneumothorax, Thrombosis (coronary and pulmonary) and trauma
