Service learning across medical schools is non-standardized and the skills that they learn can vary. Project HEART, a volunteer-based outreach program focused on teaching cardiovascular health and cardiopulmonary resuscitation (CPR) at public high schools, was implemented to encourage greater community engagement and equilibrate skill acquisition across different service projects. This pilot study characterized the benefits of providing service learning opportunities to first-year medical students. First-year medical students at a single institution were recruited to Project HEART. Following service sessions, all students completed a retrospective pre/post survey. They provided self-reported scores on a five-point Likert-type scale, grading their didactic and communication skills before and after the event. Subjective feelings of community engagement were also queried. Overall, 30 students were recruited across nine different community programs. Following participation, significantly increased confidence was seen in performing hands-only CPR (p < 0.001), public speaking (p = 0.003), teaching effectively (p < 0.001), and explaining medical terminology to laypersons (p < 0.001). Volunteers had an increased sense of community engagement (p < 0.001) and 17/30 students expressed greater consideration towards specializing in cardiology, primary care, or entering academia after participation. The study supported the proposal that service learning may promote self-determined altruism, positively influence perceptions of community stewardship, and have positive subjective benefits on medical student education.

Objectives: The objectives of this study were to determine the suitability of the low-fidelity/low-cost simulator “Salvando a Rosita^®” in the acquisition of “hands-only CPR” skills by adult nursing degree students. Methods: A quasi-experimental quantitative study was carried out with a single experimental group that included 89 nursing degree students; it was conducted in November and December 2024 at the National University of Trujillo, Peru. Results: The STAI-TA score was 17.30, and the STAI-SA score was 37.00 points. Women showed a greater level of SA (p = 0.002). The required effort was described by women as being high and by men as light (p < 0.001). The compression rate was 125.7, and the percentage of compressions with an adequate depth was 89.6%. Overweight/obese individuals achieved more correct compressions (p < 0.01). The attitudes toward alerting emergency services, remaining calm while a person is in cardiac arrest, applying the CPR sequence automatically, and performing CCs were better after receiving training. The majority considered the “Salvando a Rosita^®” simulator to be useful for teaching “hands-only CPR” to students in the first cycles of a nursing degree. Conclusions: The “Salvando a Rosita^®” simulator was found to be an appropriate tool for teaching “hands-only CPR” to students in either the first cycles of health sciences or in other related professions.

Background/Objectives: Effective infant cardiopulmonary resuscitation (CPR) relies on high-quality chest compressions, yet the optimal technique for single-rescuer scenarios remains debated. Although widely used, the two-finger technique (TFT) is associated with an inadequate compression depth and increased rescuer fatigue. While the two-thumb encircling hands technique (TTHT) provides a superior compression depth, its application in single-rescuer scenarios is impractical. This study evaluates a novel technique (nT) as a potential alternative, aiming to optimize both compression efficacy and rescuer endurance. Methods: This randomized crossover study assessed the efficacy of the TFT, TTHT, and nT in a simulated infant CPR setting. Medical students trained in newborn and infant resuscitation performed all three techniques in a controlled environment using a high-fidelity neonatal simulator. We objectively measured and compared key CPR performance metrics, rescuer fatigue, and hand pain among the techniques. Results: The nT and TTHT outperformed the TFT in compression depth, rescuer endurance, and overall CPR quality. The nT achieved the highest adequate compression rate (92.4% vs. 78.6% for TTHT and 65.2% for TFT) while minimizing fatigue (RPE: 3.1 vs. 4.5 for TTHT and 6.2 for TFT) and hand pain (NRS: 1.8 vs. 3.9 for TTHT and 5.4 for TFT). TTHT produced the deepest compressions (mean: 44.2 mm vs. 42.9 mm for nT and 38.6 mm for TFT, p < 0.001). Rescuer anthropometric factors (sex, weight, and height) affected all techniques similarly, suggesting no inherent advantage based on body characteristics. Conclusions: Both the nT and TTHT outperformed the TFT, with the nT demonstrating superior rescuer endurance while maintaining high-quality compressions. Given its ergonomic benefits and effectiveness, the nT emerges as a promising alternative for single-rescuer infant CPR and warrants consideration for future resuscitation guidelines. Full article

Background: Layperson cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use are vital for improving survival rates after out-of-hospital cardiac arrest (OHCA), yet their application varies by community demographics. We evaluated the concerns and factors influencing willingness to perform CPR and use AEDs among laypersons in high-risk, low-resource communities. Methods: From April 2022 to March 2024, laypersons in Northern Manhattan’s Community District 12 completed surveys assessing their attitudes toward CPR and AED use before attending Hands-Only CPR training. Fisher’s Exact Test assessed differences in concerns and willingness to perform CPR and AED use across racial-ethnic groups and compared low-resource communities with high-resource groups consisting of non-clinical staff across eight ambulatory sites. Results: Among 669 participants from low-resource communities, 64% identified as Hispanic, 58% were under 40 years of age, and 67% were female. Significant knowledge gaps were identified: 62% had never learned CPR, and 77% were unfamiliar with AEDs. Top concerns about giving CPR included fear of incorrect performance (67%), causing harm (56%), and legal repercussions (53%). Willingness to perform CPR was most influenced by familiarity with the victim. The primary barrier to AED use was a lack of operational knowledge (66%). Non-Hispanic Black participants expressed significantly greater concerns than their Non-Hispanic White counterparts. Participants in high-resource settings (n = 309) showed higher training rates, albeit with similar apprehensions about CPR and AED use. Conclusions: Concerns regarding CPR and AED use stem from a lack of confidence and training, particularly predominant in certain racial-ethnic groups. Targeted, culturally sensitive community interventions could potentially address these barriers, enhance preparedness, and improve OHCA survival rates. Full article

Despite the increasing incidence of myocardial infarction among middle-aged adults, studies analyzing their recognition of early myocardial infarction symptoms and cardiopulmonary resuscitation training experiences are lacking. This study aimed to utilize data from the 2022 Korea Community Health Survey to assess the level of recognition of early myocardial infarction symptoms among middle-aged adults and identify factors affecting cardiopulmonary resuscitation performance based on training experiences. Secondary data analysis was conducted to assess 99,945 adults aged 40–64 years on their recognition of early myocardial infarction symptoms and the influence of cardiopulmonary resuscitation training experience on their performance ability. Data analysis was performed using multinomial logistic regression, followed by assessing the area under the curve and visualizing the receiver operating characteristic curve to evaluate the model’s performance. The recognition of early myocardial infarction symptoms improved; the cardiopulmonary resuscitation performance ability increased by 22%. The absence of training with mannequins and automated external defibrillators resulted in a 79% and 77% decrease in cardiopulmonary resuscitation performance ability, respectively. Enhancing the recognition of early myocardial infarction symptoms and providing hands-on cardiopulmonary resuscitation training is vital for improving cardiopulmonary resuscitation performance in middle-aged adults. Effective cardiopulmonary resuscitation training programs can facilitate the rapid identification of patients who have had a cardiac arrest, bolster emergency response capabilities, and enhance the overall social safety net.

Introduction: Numerous educational programs recommend implementing the teaching principles of BLS from an early age. The aim of this study was to evaluate selected parameters of the quality of resuscitation performed by children aged 10–14 years during simulated circulatory arrest in an adult. Materials and Methods: The project involved four stages, culminating in students performing thoracic compressions on an adult simulator for 2 min. A digital analysis of the quality, depth, relaxation and rate of compressions allowed us to formulate results and conclusions. The authors’ proprietary questionnaire form allowed for the correlation of criteria such as age, gender, body mass and past experience in first aid training of the participant. Results: A total of 149 girls and 130 boys were studied. The mean age was 12 years (SD ± 1.41). A directly proportional increase in body mass with participant age was observed (p < 0.000). Children as young as 10 years old achieved only 24.13% quality, while those at the age of 14 demonstrated a more than doubled value (67.61%). The minimum depth of chest compressions recommended for an adult (5–6 cm) was not reached in any age group. Girls from all grades achieved a mean quality of 44.69% (SD ± 32.57), while boys achieved a score of 60.23% (SD ± 31.74). On the other hand, in the case of evaluating thoracic relaxation, a significantly better result was achieved by girls compared to boys (66.14% vs. 56.78%; rho-Spearman test for p = 0.011). Conclusions: Age, sex and body mass play important roles in the quality of resuscitation provided by children. None of the age groups studied achieved the minimum mean depth during adult thoracic compressions under simulated conditions. It is recommended to modify school-based BLS classes to better match the exercises to students’ predispositions. Full article

The prognosis for patients with out-of-hospital cardiac arrest (OHCA) has been reported to be worse in the cold season. On the other hand, it is unclear whether a similar trend exists in OHCA patients who are treated with extracorporeal cardiopulmonary resuscitation (ECPR). This study was a retrospective multicenter registry study. We examined the association between ECPR and season. We compared the prognosis in four seasonal groups according to the day of occurrence. Multivariable logistic regression analysis was performed for the assessment of clinical and neurological outcomes. A total of 2024 patients with OHCA who received ECRP were included. There were no significant differences in in-hospital mortality (p = 0.649) and in the rate of favorable neurological outcome (p = 0.144). In the multivariable logistic regression, the seasonal factor was not significantly associated with worse in-hospital mortality (p = 0.855) and favorable neurological outcomes (p = 0.807). In this study, there was no seasonal variation in OHCA patients with ECPR. Full article

Background: The potential use of manikins made of environmentally friendly materials (biodegradable or easily recycled) could be a milestone in promoting cardiac arrest awareness and mass resuscitation training without the threat of generating large amounts of unprocessable waste. The main aim of the study was to compare the attitude of young adults from Asia and Poland towards cardiopulmonary resuscitation training forms and to evaluate the innovative concept of an ecological resuscitation manikin; Methods: This was a survey-based study conducted during two events in Thailand and Poland in 2023; Results: A total of 226 questionnaires were included in the final analysis. Asian respondents were significantly more likely to choose traditional training than Polish participants (78% vs. 58%, respectively). A manikin that is mainly biodegradable was the most common choice across the entire study group. Young Asians were significantly more likely to choose a traditional stationary course, while Polish respondents were highly significantly more likely to opt for hybrid training (online with practical training provided at the student’s home). Conclusions: In the total study group, young people from Poland and parts of Asia are most likely to participate in traditional on-site instructor-led training, but a comparison across groups showed a significant tendency for young Poles to choose a hybrid training option, i.e., a combination of online and hands-on training. Despite some differences, both study groups showed a strong interest in pro-environmental behavior and the use of more ecofriendly solutions than previously used in resuscitation training.

Background: Out-of-hospital cardiac arrest is considered a global problem. In the last few years, there has been a growing interest in telephone-cardiopulmonary resuscitation guided by a telecommunicator. Indeed, several studies have demonstrated that it increases the chances of survival rate. This study focuses on the key points the operator should follow when performing telephone-cardiopulmonary resuscitation. The main objective of this paper is to design an algorithm to improve the telephone-cardiopulmonary resuscitation response protocol. Methods: The available evidence and the areas of uncertainty that have not been previously mentioned in the literature are discussed. All the information has been analyzed by two discussion groups. Later, a consensus was reached among all members. Finally, a response algorithm was designed and implemented in clinical simulation. Results: All the witnesses were able to recognize the OHCA, call for emergency assistance, follow all the operator’s instructions, move the victim, and place their hands in the correct position to perform CPR. Discussion: The results of the pilot study provide us a basis for further experimental studies using randomization and experimental and control groups. Conclusions: No standardized recommendations exist for the operator to perform telephone-guided CPR. For this reason, a response algorithm was designed. Full article

Background: Chest compression and defibrillation are essential components of cardiac arrest treatment. Mechanical chest compression devices (MCCD) and automated external defibrillators (AED) are used separately in clinical practice. We developed an automated compression–defibrillation apparatus (ACDA) that performs mechanical chest compression and automated defibrillation. We investigated the performance of cardiopulmonary resuscitation (CPR) with automatic CPR (A-CPR) compared to that with MCCD and AED (conventional CPR: C-CPR). Methods: Pigs were randomized into A-CPR or C-CPR groups: The A-CPR group received CPR+ACDA, and the C-CPR group received CPR+MCCD+AED. Hemodynamic parameters, outcomes, and time variables were measured. During a simulation study, healthcare providers performed a basic life support scenario for manikins with an ACDA, MCCD, and AED, and time variables and chest compression parameters were measured. Results: The animals showed no significant in hemodynamic effects, including aortic pressures, coronary perfusion pressure, carotid blood flow, and end-tidal CO₂, and resuscitation outcomes between the two groups. In both animal and simulation studies, the time to defibrillation, time to chest compression, and hands-off time were significantly shorter in the A-CPR group than those in the C-CPR group. Conclusions: CPR using ACDA showed similar hemodynamic effects and resuscitation outcomes as CPR using AED and MCCD separately, with the advantages of a reduction in the time to compression, time to defibrillation, and hands-off time.

The spread of infectious diseases has accelerated the transition from face-to-face (F2F) to non-F2F (NF2F) education. To maintain the effect of successful NF2F education in cardiopulmonary resuscitation, reorganizing the curriculum to suit the NF2F educational environment is necessary. We propose an appropriate learning curriculum for NF2F basic life support (BLS) training for laypersons based on expert surveys and learners’ performance outcomes. This study included three stages and used multiple methods. A draft curriculum was created through a literature review and three-round Delphi approach, and then applied as a test for actual education. After the training, the final curriculum of the NF2F BLS training for laypersons was proposed by reflecting on the performance outcomes of learners and expert opinions. NF2F theoretical education was simplified into five content items: concept of chain of survival, legal protection for first aiders, importance of bystander cardiopulmonary resuscitation, how to recognize a patient in cardiac arrest and activate the emergency medical services system, and reduced training time. In the hands-on skills session, it was recommended to practice chest compressions using a simple intuitive feedback device and to use automated external defibrillators step-by-step more than in F2F training. In conclusion, NF2F training is a suitable option for BLS training methods in situations where F2F training is difficult. Full article

This study aims to present a novel deep learning algorithm for a sliding shock advisory decision during cardiopulmonary resuscitation (CPR) and its performance evaluation as a function of the cumulative hands-off time. We retrospectively used 13,570 CPR episodes from out-of-hospital cardiac arrest (OHCA) interventions reviewed in a period of interest from 30 s before to 10 s after regular analysis of automated external defibrillators (AEDs). Three convolutional neural networks (CNNs) with raw ECG input (duration of 5, 10, and 15 s) were applied for the shock advisory decision during CPR in 26 sequential analyses shifted by 1 s. The start and stop of chest compressions (CC) can occur at arbitrary times in sequential slides; therefore, the sliding hands-off time (sHOT) quantifies the cumulative CC-free portion of the analyzed ECG. An independent test with CPR episodes in 393 ventricular fibrillations (VF), 177 normal sinus rhythms (NSR), 1848 other non-shockable rhythms (ONR), and 3979 asystoles (ASYS) showed a substantial improvement of VF sensitivity when increasing the analysis duration from 5 s to 10 s. Specificity was not dependent on the ECG analysis duration. The 10 s CNN model presented the best performance: 92–94.4% (VF), 92.2–94% (ASYS), 96–97% (ONR), and 98.2–99.5% (NSR) for sliding decision times during CPR; 98–99% (VF), 98.2–99.8% (ASYS), 98.8–99.1 (ONR), and 100% (NSR) for sliding decision times after end of CPR. We identified the importance of sHOT as a reliable predictor of performance, accounting for the minimal sHOT interval of 2–3 s that provides a reliable rhythm detection satisfying the American Heart Association (AHA) standards for AED rhythm analysis. The presented technology for sliding shock advisory decision during CPR achieved substantial performance improvement in short hands-off periods (>2 s), such as insufflations or pre-shock pauses. The performance was competitive despite 1–2.8% point lower ASYS detection during CPR than the standard requirement (95%) for non-noisy ECG signals. The presented deep learning strategy is a basis for improved CPR practices involving both continuous CC and CC with insufflations, associated with minimal CC interruptions for reconfirmation of non-shockable rhythms (minimum hands-off time) and early treatment of VF (minimal pre-shock pauses).

Acute variceal bleeding (AVB) is a potentially fatal complication of clinically significant portal hypertension and is one of the most common causes of acute upper gastrointestinal bleeding. Thus, esophagogastric varices represent a major economic and population health issue. Patients with advanced chronic liver disease typically undergo an upper endoscopy to screen for esophagogastric varices. However, upper endoscopy is not recommended for patients with liver stiffness < 20 KPa and platelet count > 150 × 10⁹/L as there is a low probability of high-risk varices. Patients with high-risk varices should receive primary prophylaxis with either nonselective beta-blockers or endoscopic band ligation. In cases of AVB, patients should receive upper endoscopy within 12 h after resuscitation and hemodynamic stability, whereas endoscopy should be performed as soon as possible if patients are unstable. In cases of suspected variceal bleeding, starting vasoactive therapy as soon as possible in combination with endoscopic treatment is recommended. On the other hand, in cases of uncontrolled bleeding, balloon tamponade or self-expandable metal stents can be used as a bridge to more definitive therapy such as transjugular intrahepatic portosystemic shunt. This article aims to offer a comprehensive review of recommendations from international guidelines as well as recent updates on the management of esophagogastric varices. Full article

Background: Many first aid programs have been conducted in schools, and researchers have identified that interventions improved students’ knowledge, skills, and attitude. This study examines the content, practices, and assessment of first aid interventions at primary schools and evaluates their effectiveness. Methods: A systematic review was undertaken. We searched MEDLINE and Cochrane library databases from January 1990 to December 2021 using the search terms: ‘’first aid’’ AND ‘’primary school children’’. School-based first aid training targeting 6 to 10 years old studies in English were eligible for inclusion. Results: We included 11 studies that were approached by experimental (n = 6) and by observational studies (n = 5). Researchers conducted interventions in Europe (n = 9) and America (n = 2). An essential part of the teaching was hands-on practice. Most studies included in their program cardiopulmonary resuscitation (n = 8) and basic life support (n = 7). The main findings showed that trained children have significantly better knowledge of and skills in first aid than those before or without training. Children under 11 years old were not strong enough to achieve the proper depth of chest compressions. Depth of chest compressions correlates with children’s age, weight, height (n = 2), and body mass index (n = 3). Conclusions The effectiveness of resuscitative or non-resuscitative first-aid training for primary school children improved students’ knowledge and skills. Subsequent research could investigate children’s reactions in actual first aid conditions. Full article

Since a great number of infant cardiopulmonary arrests occur outside of the hospital, it is crucial to train laypersons in cardiopulmonary resuscitation techniques, especially those professionals that will work with infants and children. The main objective of this study was to evaluate the efectiveness of ventilations performed by professional training students. The secondary objective was to analyze the preference between different ventilation and chest-compression methods. The sample consisted of 32 professional training students, 15 preschool students, and 17 physical education students. The activity was conducted separately for each group, and we provided a 10 min theoretical training about infant basic life support followed by a 45 min practical training using a Laerdal Little Anne QCPR CPR manikin. A practical test in pairs was organized to record the ventilation as performed by the participants, establishing the difference between the efficacious and the non-efficacious ones. Furthermore, we handed out a survey before and after training to evaluate their knowledge. More than 90% of the students completely agreed with the importance of learning cardiopulmonary resuscitation techniques for their professional future. More than half of the sample considered that they perform the rescue breathings with the mouth-to-mouth method better. We observed that through mouth-to-mouth-nose ventilations, the number of effective ventilations was significantly higher than the effective ventilations provided by a self-inflating bag and mask (EffectiveMtoMN 6.42 ± 4.27 vs. EffectiveMask 4.75 ± 3.63 (p = 0.007)), which was the preferred method. In terms of the compression method, hands encircling the chest was preferred by more than 85% of students. Mouth-to-mouth nose ventilation is more efficient than bag-face-mask ventilation in CPR as performed by professional training and physical activity students. This fact must be considered to provide higher-quality training sessions to professional training students. Full article
