Guideline-directed therapy during the first minutes of resuscitation may be life saving. This study assessed the performance of American Heart Association (AHA) guidelines by trained departmental staff in the period between discovery of collapse and emergency team arrival. ⋯ Trained departmental staff performed poorly in the moments between patient discovery and arrival of the emergency team. Since patient outcomes were comparable to those described in the literature, poor resuscitation performance may be commonplace in hospitals where ward personnel are expected to deliver advanced life support prior to arrival of the emergency team.

Randomized Controlled Trial
The quality of chest compressions by trained personnel: the effect of feedback, via the CPREzy, in a randomized controlled trial using a manikin model.
Even after training, the ability to perform effective cardiac compressions has been found to be poor and to decrease rapidly. We assessed this ability with and without a non-invasive feedback device, the CPREzy, during a 270s CPR session in an unannounced, single-blinded manikin study using 224 hospital employees and staff chosen at random and using a non-cross over design. The two groups self-assessed their knowledge and skills as adequate. ⋯ If compressions were effective initially, the time until >50% of compressions were less than 4 cm deep was 75+/-81s in the control group versus 194+/-87 s in the CPREzy group (P=0.0001 [-180 to -57.5]). After a few seconds of training in its use, our candidates used the CPREzy effectively. Against the background knowledge that estimation of compression depth by the rescuer or other team members is difficult, and that performing effective compressions is the cornerstone of any resuscitation attempt, our data suggests that a feedback device such as the CPREzy should be used consistently during resuscitation.

We sought to evaluate the knowledge of probable outcome by medical personnel for in-hospital and out-of-hospital cardiac arrests, and self-reported history of CPR training referrals for family members of cardiac patients. ⋯ This study demonstrates that medical experience is not associated with accurate estimates of cardiac arrest survival. Overwhelmingly, medical personnel believe family members should be trained to perform CPR, however, few refer family members for CPR training.

To evaluate the outcome and the factors concerned with of out-of-hospital cardiac arrest patients according to the location of the collapse. ⋯ Although the majority of out-of-hospital cardiac arrests occur at private residences, arrests in public or in the work place had a higher chance of being found in ventricular fibrillation and survival than those at private residences. In order to establish a system to improve the outcome of out-of-hospital cardiac arrest, a well-considered strategy considering the location of arrest is necessary.

Cerebral resuscitation is the most important goal of advanced life support. Currently, there are no objective monitoring methods available to gauge the effectiveness of advanced life support on cerebral resuscitation. We assessed the utility of bispectral index (BIS) monitoring during cardiopulmonary resuscitation as a marker of cerebral resuscitation. ⋯ Illustrative data are presented, outlining the process of evaluation undertaken. A major component of the BIS tracing during external chest compressions appears to be due to movement artefact. Our pilot data indicate that with current technology, BIS monitoring is not a clinically reliable marker of the efficacy of external chest compressions.
