Early bystander cardiopulmonary resuscitation (CPR) is essential for survival from out-of-hospital cardiac arrest (OHCA). Young people are potentially important bystander CPR providers, as basic life support (BLS) training can be distributed widely as part of the school curriculum. ⋯ Young Norwegians are motivated to perform bystander CPR, but barriers are still seen when more detailed cardiac arrest scenarios are presented. By providing students with good quality BLS training in school, the upcoming generation in Norway may strengthen the first part of the chain of survival in OHCA.

The aim of this study was to study exercise-related cardiac arrests on the tennis court and investigate the impact of early initiation of cardiopulmonary resuscitation on survival rate and outcome. ⋯ Cardiac arrest on the tennis court is a predominantly witnessed event with a respectively high rate of bystander CPR, which reflects in a high successful survival rate.

In the present study, we investigated trans-nasal cooling in settings of pulseless electrical activity (PEA). We hypothesized that early trans-nasal cooling during CPR improves outcomes when cardiac arrest is associated with PEA. ⋯ When selective trans-nasal cooling was initiated during CPR in the animal model of prolonged cardiac arrest with PEA, CPP was higher and the likelihood of return of spontaneous circulation was improved.

We showed previously that ivabradine (IVA), a selective inhibitor of the cardiac pacemaker I(f) current, achieved protection against ischaemia-induced ventricular fibrillation (VF) in pigs by increasing the VF threshold (VFT). This was correlated to the heart rate reduction (HRR), the limitation of monophasic action potential shortening and the reduction of the hypoxic area. This study investigated myocyte ultrastructure and regional myocardial blood flow (RMBF), potentially involved in these cardioprotective effects of IVA. ⋯ IVA exerts a cardioprotection from ischaemia-induced VF by increasing RMBF and preserving cardiomyocyte and mitochondrial ultrastructure, which opens new perspectives regarding potential targets that would be involved in the anti-ischaemic effects of IVA.
