Narrow-Complex PEA
Point of care ultrasound (POCUS) can quickly aid in identification of mechanical causes of PEA. A collapsed right ventricle suggests an inflow obstruction (i.e tamponade, pneumothorax, or hyperinflation) whereas a dilated right ventricle indicates outflow obstruction (i.e. Pulmonary emobolism).
Most Common Causes:
-Cardiac Tamponade
-Tension Pneumothorax
-Mechanical Hyperinflation
-Pulmonary Embolism
Treatment:
-Aggressive intravenous fluid administration
-Cardiac Tamponade –> Pericardiocentesis
-Tension Pneumothorax –> Needle decompression
-Mechanical Hyperinflation –> Adjust ventilator
-Pulmonary Embolism –> Thrombolytic therapy #Diagnosis #Management #CriticalCare #PEAArrest #NarrowComplex #Differential #Evaluation #Algorithm
