Summary: After the implementation of the HeartRescue project, improvements in bystander CPR and first-responder defibrillation were seen in both Black and White patient groups, but survival to discharge only significantly increased for White patients.

Summary: The COVID-19 pandemic has significantly affected the prehospital care processes for out-of-hospital sudden cardiac arrest, including an increase in home-based cardiac arrest, a decrease in bystander defibrillation rate, and a longer EMS call-to-arrival time.

Summary: This study investigated the annual patterns of prognosis and treatment in pediatric patients with out-of-hospital cardiac arrest (OHCA) in Japan. Despite the increase in rates of bystander-initiated CPR and pre-hospital adrenaline administration, there was no significant change in one-month survival.

Summary: The Danish Cardiac Arrest Registry aims to monitor and evaluate the quality of prehospital cardiac arrest treatment and facilitate research. It records descriptive and qualitative variables related to out-of-hospital cardiac arrest and provides important data for assessing treatment protocols and patient outcomes. The registry is one of the oldest and most comprehensive national clinical registries in Denmark, playing a crucial role in improving the care for patients suffering from out-of-hospital cardiac arrest.

Summary: The study highlights the association between air pollutants, particularly PM2.5/PM10 and heavy metal content, with incidences of OHCA. Nickel and arsenic exposure are linked to the initial shockable rhythm and effectiveness of CPR in OHCA patients, while overall mortality is also related to pollutant levels.

Summary: This study aimed to investigate the feasibility of delivering AEDs by drones in real-life cases of OHCA. The results showed that the AED delivery success rate was 92%, with 64% of cases where drones arrived before ambulances, resulting in a median time benefit of 01:52 minutes. However, further improvements are needed to increase dispatch rate and time benefits.

Summary: This study identified a significant association between initial serum pH value and 1-month survival among pediatric out-of-hospital cardiac arrest (OHCA) patients. Patients with lower initial pH values had lower survival rates.

Summary: This network meta-analysis aimed to evaluate the effect of early coronary angiography (CAG) compared with selective CAG (late and no CAG) for patients after out-of-hospital cardiac arrest without ST-elevation myocardial infarction (NSTE-OHCA). The meta-analyses showed that early CAG was associated with a statistically significant increase in overall survival compared to selective CAG. However, this effect was not observed in the subgroup analysis of randomized controlled trials (RCTs). The network meta-analysis based on non-randomized studies (NRS) indicated a significant increase in survival with late CAG compared to early CAG.

Summary: This study found that extreme heat and extreme cold are associated with an increased risk of out-of-hospital cardiac arrest (OHCA), while temperature variation does not show a significant association. The elderly and males appear to be more vulnerable to the effects of temperature extremes. However, due to limited geographical coverage, further confirmation of these findings in different regions is urgently needed.

Summary: The study found that bystander physical limitations contribute to delayed chest compressions, resulting in lower chances of receiving CPR, longer time to initiate compressions, and lower survival rates.

Summary: This study explores the characteristics and motivational factors for joining a smartphone-based CPR lay responder system. The results show that motivation mainly depends on intrinsic factors, such as an inner belief of doing good, but there are also extrinsic factors, such as earning rewards. Focusing information campaigns on intrinsic factors is crucial for successful recruitment, and CPR instructors and workplaces play a key role.

Summary: This study evaluated the usefulness of a chatbot as an assistant during CPR care by laypersons. The results showed that the chatbot was able to guide users in recognizing cardiac arrest and performing chest compressions, and the majority of participants performed well throughout the process.

Summary: This study analyzed the association between physical activity level and the quality of CPR performed by laypeople in an eight-minute scenario. Results showed that participants with higher physical activity levels had better compression depth performance during CPR. However, after controlling for other factors, the association between physical activity level and CPR performance was no longer significant.

Summary: This study in Okayama, Japan described the characteristics, prevalence, and outcomes of out-of-hospital cardiac arrest (OHCA) patients with do not attempt resuscitation (DNAR) orders, as well as the factors associated with emotional stress experienced by emergency medical technicians (EMTs) when treating them. The results showed that approximately 30% of EMTs experienced high levels of stress when treating DNAR patients. The establishment of a prehospital emergency system incorporating physician medical direction and updated guidelines may help reduce the psychosocial stress of EMTs.

Summary: This study visualized the closure of vocal cords during apnea, in between breaths, and during breath holds in preterm infants using ultrasonography. The closure of vocal cords impaired the effect of respiratory support.
