Can focused echocardiographic evaluation in life support (FEEL) be used to predict resuscitation outcome or termination of resuscitation (TOR)? A prospective trial

Patients and methods We performed a prospective, observational study of nonconsecutive, non-trauma, adult, out of hospital cardiac arrest (OHCA) patients. This study conducted in emergency department of single tertiary university hospital. Echo performed every 2 minute simultaneously with pulse check within 10 second throughout the arrest, which was managed by the usual advanced cardiac life-support treatment guidelines. We obtained sub-xiphoid or parasternal long axis view of echo. We defined echocardiographic evidence of cardiac kinetic activity as any detected motion of the myocardium, ranging from visible ventricular fibrillation to coordinated ventricular contractions.
