Post Arrest Care/PEA Flashcards
What type of trauma arrest has a lower survival rate? Blunt or Penetrating?
Blunt
Causes of trauma arrest?
Central Blood Loss Tamponade Hypoxia Hypothermia Pneumothroax Aortic Rupture Electrocution Drowning
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.
Survival low
Failure of sodium-potassium pump
GI loss
Severe acidosis
Myocardial ischemia, infarction
Causes of young “healthy” arrest.
Brugada syndrome
Long QT Syndrome
Hypertrophic Cardiomyopathy
Commotio Cordis
“Trauma”
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
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?
Hypovolemia
Cardiac tamponade
Tension pneumothorax
Hypoxemia
Acidosis
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
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
