Using the Pulseless Arrest Algorithm for Managing PEA

Using the Pulseless Arrest Algorithm for Managing PEA

Oct 6, 2017
Version control: This document is current with respect to 2015 American Heart Association Guidelines for CPR and ECC. These guidelines are current until they are replaced on October 2020. If you are reading this page after October 2020, please contact ACLS Training Center at support@acls.net for an updated document.
Patients with PEA have poor outcomes. Their best chance of returning to a perfusing rhythm is through the quick identification of an underlying reversible cause and correct treatment. As you use the algorithm to manage the PEA patient, remember to consider all the H's and T's, particularly hypovolemia, which is the most common cause of PEA. Also look for drug overdoses or poisonings.
Begin with the primary survey to assess the patient's condition:
  1. Pulseless Electrical Activity (PEA) occurs when you see a rhythm on the monitor that would normally be associated with a pulse, however the patient is pulseless.
  2. The rhythm can be anything, at any heart rate
  3. There is something preventing the heart from generating a pulse, such as being empty (Hypovolemia) something pushing against it (Tamponade)
  4. Re-assess the patient frequently for the return of pulses
Follow the ACLS Pulseless Arrest Algorithm
  1. Begin CPR as soon as pulselessness is recognized. Continue CPR at a rate of 100 to 120 per minute throughout the resuscitation without interruptions of more than 10 seconds to evaluate for pulses.
  2. Compressors should be switched every 2 minutes to ensure efficacy of compressions
  3. Ventilate the patient using a Bag Valve Mask (or advanced airway if already in place) at a rate of 10 per minute
  4. Waveform capnography should be utilized to monitor efficacy of compressions (should generate at least 10) and the return of pulses (will cause an increase in capnography to 40)
  5. Obtain IV/IO access
  6. Administer Epinephrine 1 mg IV/IO every 3-5 minutes
  7. Find and treat underlying causes.
Two management priorities are maintaining high quality CPR and searching simultaneously for a treatable cause of the patient's PEA. Stop CPR only when absolutely necessary for pulse and rhythm checks. Establishing IV/IO access is a priority over advanced airway management. If an advanced airway is placed, change to continuous chest compressions without pauses for breaths. Give 10 breaths per minute and check rhythm every 2 minutes.
As soon as an underlying cause is identified, it should be treated. For example, if hypovolemia is identified as a possible cause of cardiac arrest, volume replacement should be started promptly. If tamponade, pericardialcentesis should occur rapidly. Without the treatment of the cause of arrest, neuro intact survival becomes unlikely.

BASIC LIFE SUPPORT FOR INFANT

PHRONESIS MEDICARE INTERNATIONAL BLS overview for infant Basic life support (BLS) is a basic level of medical care used to help sustain a person who is experiencing cardiac arrest or respiratory failure, until they can be given full medical care by an advanced responder. BLS can be used in any scenario where breathing or heartbeat has been compromised, such as drowning, heart attack, or severe shock (eg, severe loss of blood). BLS is more comprehensive than CPR alone, since it covers additional steps that are not expected from a layperson, as well as techniques for working with other rescuers. The techniques used for BLS vary slightly depending on whether the victim is an adult, child, or infant. This module explains the techniques and procedure for performing BLS on an infant. The adult and child procedures are covered in separate modules. Note: The term 'infant' in this context refers to neonates outside the delivery room setting, up to 12 months old. Children 12...

Types of paramedics

Types of Paramedics Paramedics provide emergency medical response to more than 6 million people in an area of more than 227,000 square kilometres. In 2015-16, paramedics in Victoria responded to about 589,847 emergency road incidents – that’s one every 55 seconds. Paramedic expertise is not just applied at the scene of a patient. Paramedics are involved in the coordination of ambulance resources and dispatch as duty managers, clinicians and communications support personnel. Paramedics are also involved in our Secondary Triage Service which deals with 000 calls classified as low medical priority, where the patient’s condition indicates that an ambulance may not be necessary and an alternative service can be provided. This helps free up ambulances for life-threatening cases. The clinical, pharmacological and medical skills of our paramedics are of a very high standard. External surveys show that 97 per cent of patients are satisfied or very satisfied with overall with our ser...

State of emergency medical services in Nigeria

EMERGENCY MEDICAL SERVICES (LASEMS AND LASAMBUS) EMERGENCY MEDICAL SERVICES (LASEMS AND LASAMBUS) Increasing urbanization and industrialization of Lagos State has led to an appreciable increase in the number of road traffic, industrial and marine accidents and medical emergencies, hence the strengthening of the inherited base hospital care i.e. Lagos State Emergency Medical Service (LASEMS) and establishment of the pre-hospital care service i.e. Lagos State Ambulance Service (LASAMBUS) in March 2001. Both services run on a 24/7 basis and have led to significant improvement in the response time and quality of care with attendant improvement in morbidity and mortality rates occasioned by medical emergencies. These services cover: • Awareness campaign on the preventive aspect of medical emergencies including home/road traffic/industrial accidents; and how to access services. • Training of personnel in pre-hospital and hospital-based management of trauma and medical emergencies, and effec...
