AbstractCardiac arrest is a condition frequently encountered byphysicians in the hospital setting including the EmergencyDepartment, Intensive Care Unit and medical/surgicalwards. This paper reviews the current literature involvingthe use of ultrasound in resuscitation and proposes analgorithmic approach for the use of ultrasound duringcardiac arrest. At present there is the need for a means ofdifferentiating between various causes of cardiac arrest,which are not a direct result of a primary ventriculararrhythmia. Identifying the cause of pulseless electricalactivity or asystole is important as the underlying cause iswhat guides management in such cases. This approach,incorporating ultrasound to manage cardiac arrest aids inthe diagnosis of the most common and easily reversiblecauses of cardiac arrest not caused by primary ventriculararrhythmia, namely; severe hypovolemia, tensionpneumothorax, cardiac tamponade, and massivepulmonary embolus. These four conditions are addressedin this paper using four accepted emergency ultrasoundapplications to be performed during resuscitation of acardiac arrest patient with the aim of determining theunderlying cause of a cardiac arrest. Identifying theunderlying cause of cardiac arrest represents the one ofthe greatest challenges of managing patients withasystole or PEA and accurate determination has the

We include several clinical imagesdemonstrating examples of cardiac tamponade, massivepulmonary embolus, and severe hypovolemia secondaryto abdominal aortic aneurysm. In conclusion, this protocolhas the potential to reduce the time required to determinethe etiology of a cardiac arrest and thus decrease the timebetween arrest and appropriate therapy.
