Shorter pauses in cardiopulmonary resuscitation (CPR) are associated with better health outcomes after out-of-hospital cardiac arrest (OHCA). Our primary objective was to examine the effect of a RapidShockTM defibrillator software upgrade compared with standard defibrillator software on the length of perishock pause during care for OHCA among adults. Secondary objectives were to assess the effects of RapidShockTM on other CPR pauses. ⋯ Overall, we observed that the use of "RapidShockTM" defibrillator software was associated with shorter CPR pauses compared with the "Standard" software. Additional studies are required to examine whether further reductions in CPR pauses may be achieved and to investigate associations between shorter CPR pauses and health outcomes.

Many American police organizations respond to out-of-hospital cardiac arrest (OHCA). This study sought to: 1) explore variation in the role of police in OHCA across emergency medical systems and 2) identify factors influencing this variation. ⋯ Police serve numerous on-scene and supplementary roles in OHCA response across jurisdictions. Their roles were influenced by multiple factors at each site. Future studies may help to better understand the value of and how to optimize police engagement in OHCA response.

Out-of-hospital cardiac arrest (OHCA) poses major public health issues. Pre-arrest heart function is a prognostic factor, but the specific contribution of pre-arrest echocardiographic evaluation in predicting OHCA outcome remains limited. ⋯ In adult, nontraumatic, EMS-treated OHCA patients, a higher LVEF 6 months prior to OHCA was associated with improved survival at hospital discharge.

Early defibrillation with an automated external defibrillator (AED) can effectively improve the survival rate of patients with out-of-hospital cardiac arrest (OHCA). Placing AEDs in public locations can reduce the defibrillation response interval from collapse to defibrillation. Most public AEDs are currently placed in a stationary way (S-AED) with limited coverage area. Bus mounted AED (B-AED) can be delivered directly to the demand point. Although B-AEDs are only available during bus operating hours, they provide greater coverage area. When the number of available AEDs is insufficient, better coverage may be achieved by placing a portion of AEDs as B-AEDs. Our purpose is developing a model to determine the optimal locations of B-AEDs and S-AEDs with a predetermined number of available AEDs. The goal is to maximize the total coverage level of all demand points. ⋯ With a given number of available AEDs, combinational deployment of B-AEDs and S-AEDs significantly improves the coverage level. B-AEDs are recommended when AEDs are insufficient. If more AEDs are available, better coverage can be obtained with reasonable location of S-AEDs and B-AEDs.

Intensive care unit cardiac arrest among very elderly critically ill patients - is cardiopulmonary resuscitation justified?
The proportion of very elderly patients in the intensive care unit (ICU) is expected to rise. Furthermore, patients are likely more prone to suffer a cardiac arrest (CA) event within the ICU. The occurrence of intensive care unit cardiac arrest (ICU-CA) is associated with high mortality. To date, the incidence of ICU-CA and its clinical impact on outcome in the very old (≥ 90 years) patients treated is unknown. ⋯ The occurrence of ICU-CA in very elderly patients is rare but associated with high mortality. Providing CPR in this cohort did not lead to long-term survival at our centre. Very elderly patients admitted to the ICU likely benefit from supportive care only and should probably not be resuscitated due to poor chance of survival and ethical considerations. Providing personalized assurances that care will remain appropriate and in accordance with the patient's and family's wishes can optimise compassionate care while avoiding futile life-sustaining interventions.
