Question 3

Likely etiologies of Narrow Complex PEA (4)

Answer 3

Cardiac Tamponade
Tension Pneumothorax
Mechanical hyperventilation
Pulmonary Embolism

Question 4

Likely etiologies of Wide Complex PEA? (2)

Answer 4

Severe hyperkalemia (CaCl and NaHCO3)
Sodium Channel toxicity (NaHCO3)

Question 5

Define Sustained ROSC

Answer 5

Sustained ROSC is deemed to have occurred when chest compressions are
not required for 20 consecutive minutes and signs of circulation persist
