Definition

Pulseless electrical activity is defined as the absence of a pulse or cardiac contractility despite the presence of electrocardiographic activity. The most common causes are respiratory failure and hypovolemia.

Causes

Life Threatening Causes

Common Causes

The complete list of causes of PEA can be remembered using the mnemonic "The Hs and Ts".[1][2][3]

Management

Below is an algorithm summarizing the approach to a patient with pulseless electrical activity. Based on the 2010 American heart association ACLS algorithm for PEA[4]







Do's

  • Efficiency of CPR can be determined by
    • Monitoring of chest compression rate and depth
    • Adequacy of chest wall relaxation
    • Length and duration of pauses in compression and number and depth of ventilations delivered
    • Physiologic parameters; partial pressure of end-tidal CO2 [PETCO2], arterial pressure during the relaxation phase of chest compressions, central venous oxygen saturation [ScvO2]
  • Remember that the foundation of successful ACLS is good BLS , represented in prompt high-quality CPR with minimal interruptions.[5][6]
  • A new class I recommendation is the use of quantitative waveform capnography for confirmation and monitoring of endotracheal tube placement.
  • Supraglottic advanced airways continues to be an alternative to endotracheal intubation for airway management during CPR.

Don'ts

  • Don't routinely use cricoid pressure during airway management of patients in cardiac arrest.
  • Don't routinely administer atropine in the management of pulseless asystole.
