Ultrasound is becoming increasingly available and incorporated into emergency medicine. Focused echocardiographic evaluation in resuscitation (FEER) is a training program available to emergency doctors in order to ensure adequate application of echocardiography in the cardiac arrest setting. The FEER protocol provides an algorithm, whereby a ?quick view? can be provided in 10 seconds during minimal interruptions in chest compressions. Performing ultrasound in the cardiac arrest setting is challenging for emergency doctors. The International Liaison Committee on Resuscitation recommend the ?quick look? echocardiography view can be obtained during the 10-second pulse check, minimizing the disruption to cardiopulmonary resuscitation.
