Randomized Controlled Trial
Smartwatches as chest compression feedback devices: A feasibility study.
Recently, there have been attempts to use smartphones and smartwatches as the feedback devices to improve the quality of chest compressions. In this study, we compared chest compression depth feedback accuracy between a smartphone and a smartwatch in a hands-only cardiopulmonary resuscitation scenario, using a manikin with a displacement sensor system. ⋯ The smartwatch-based chest compression depth feedback was more accurate than smartphone-based feedback.

Multicenter Study
Defibrillation success during different phases of the mechanical chest compression cycle.
Animal studies indicate higher termination of VF/VT (TOF) rates after shocks delivered during the decompression phase of the compression cycle for manual and mechanical CPR. We investigated TOF for shocks delivered in different compression cycle phases during load distributing band (LDB) mechanical CPR in the CIRC trial. ⋯ Shocks delivered in the compression phase of LDB chest compressions had lower TOF rates than shocks delivered while pausing the LDB device. More research is needed to see how defibrillation during chest compressions affect ROSC and survival.

Cardiopulmonary arrest is the most frequent cause of the unresponsive wakefulness syndrome: A prospective population-based cohort study in Austria.
The "Unresponsive wakefulness syndrome" (UWS) or previously termed vegetative state is a possible consequence of severe brain damage where individuals just open their eyes but show no conscious behavioural reaction. While head trauma has previously been considered the prevailing cause, clinical experience suggests shows that cardiopulmonary arrest plays an increasingly important role. We therefore attempted to study this hypothesis in a well-defined region of Austria. ⋯ Cardiopulmonary resuscitation has become the major cause of UWS which leads to an increasing incidence with age. These aspects may become even more prominent with the ageing of our population and need to be considered in the organisation of care.

To describe the echocardiographic parameters of the right ventricle (RV) in first 24h post-cardiac arrest (CA) in humans; to determine if the etiology of arrest predicts RV dysfunction; to quantify parameters of the right ventricle in the first 24h post-CA. ⋯ RV dysfunction is present in the majority of post-CA patient regardless of the etiology of arrest. Further studies are needed to investigate if there are relationships between echocardiographic findings and survival and to assess temporal findings of RV function post-CA.
