The 2010 American Heart Association (AHA) for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science has changed the basic life support (BLS) sequence from "A-B-C" to "C-A-B." The AHA explained that this change may shorten the initiation time for chest compressions. In this study, the 2010 AHA guidelines for BLS (2010-BLS) were studied through a simulation program and practiced on a manikin. The time saved in initiating initial chest compressions was calculated, and the significance of the new guidelines was evaluated. ⋯ Chest compressions were initiated earlier by health care providers who were re-educated according to the 2010 AHA guidelines.

Computed tomography (CT) has been shown to detect more injuries than plain radiography in patients with blunt trauma, but it is unclear whether these injuries are clinically significant. ⋯ Chest CT after a normal CXR result in patients with blunt trauma detects injuries, but most do not lead to changes in patient management.
