Study Notes
Pulseless Electrical Activity (PEA) and Asystole Overview
- PEA is characterized by any organized rhythm without a pulse, displaying QRS complexes that are similar but may vary in rate and regularity.
- Commonly reversible causes of PEA include hypovolemia and hypoxia.
Epinephrine Administration
- The proper dosing regimen for epinephrine in PEA or asystole is 1 mg administered IV/IO, repeated every 3 to 5 minutes.
ECG Interpretation
- An isoelectric ECG (flatline) might result from factors such as loose leads, lack of power to the monitor, or inadequate gain/amplitude settings.
Resuscitation Efforts
- Rigor mortis and clear do-not-attempt-resuscitation (DNAR) status are valid reasons to stop resuscitative efforts.
- Continuous efforts even after 20 minutes without success are grounded in clinical judgment, not strict time limits.
Advanced Airway Management
- In asystole, advanced airway insertion should be considered only if bag-mask ventilation is insufficient, prioritizing ventilation effectiveness over IV/IO access.
Amiodarone Use in PEA
- Amiodarone is not indicated for PEA; its use is reserved for ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT).
Treatment Protocols for PEA
- Treatment of PEA extends beyond standard algorithm interventions; healthcare providers must actively seek and address underlying causes for successful resuscitation.
Defibrillation in Asystole
- There is no evidence supporting the efficacy of defibrillation for asystole; attempts to shock are discouraged unless distinguishing between fine VF and asystole is necessary.
Rhythm Classification
- PEA and asystole are classified as non-shockable rhythms, which guides treatment approaches and interventions.
