Does Spontaneous Cardiac Motion, Identified With Point-of-Care Echocardiography During Cardiac Arrest, Predict Survival?

The authors included 15 studies evaluating the accuracy of outcome prediction by detection of spontaneous cardiac motion among 1,695 patients in cardiac arrest. Ten of these studies took place in the ED, 3 in the out-of-hospital setting, and 2 in a combination of out-of-hospital and ED settings. Two studies recruited trauma patients, 7 studies recruited nontrauma patients, and the remaining studies either recruited mixed populations or did not specify their patient recruitment methods. Seven studies used ultrasonography performed by advanced performers (defined as attending physicians, senior residents, or residents with formal advanced ultrasonographic training), with 6 studies conducted by intermediate-experience performers (defined as all other providers) and 2 studies using providers with both intermediate and advanced experience.
