BACKGROUND: Evidence supporting the benefits of autonomous learning of basic life support, such as rapid outcomes and cost-effectiveness, is increasing. Reports supporting the autonomous learning of cognitive skills in basic life support exist. However, there is currently no report supporting the autonomous learning of psychomotor skills in basic life support.
OBJECTIVE: This study aimed to assess how using a research-developed pillow-made mannequin affects autonomous learning of psychomotor skills in basic life support training.
METHODS: Randomized controlled trial.
METHODS: This study was conducted in a nursing school in Turkey.
METHODS: Sixty-one (n = 61) third-year formal science undergraduate students.
METHODS: At XXX University, 61 nursing students were divided into Intervention (n = 31) and Control Groups (n = 30). Students in both groups received basic life support training, including live demonstrations. Intervention Group students practiced with the mannequin for 15 days. Skill assessments were conducted by two independent evaluators using a real mannequin 15 days later and six months later. Researchers used a checklist to assess psychomotor skills.
RESULTS: The sociodemographic characteristics of both student groups were similar. There was no significant difference in cognitive knowledge levels after the blended training (p > 0.05). However, at both post-intervention assessments, after 15 days and after 6 months, significant skill differences emerged in \"placing the index finger on the ends of the sternum,\" \"combining the thumbs in the middle,\" \"defining the lower sternum as a massage point,\" \"placing the base of the chest\" \"placing the weaker hand at the massage point,\" \"placing the body perpendicular to the ribcage,\" and \"performing 30 compressions.\" Cohen\'s kappa value was calculated as 0.932.
CONCLUSIONS: Use of the mannequin facilitates autonomous learning of psychomotor skills and promotes accurate application.
BACKGROUND: ClinicalTrials.gov ID: NCT05346003, 08/02/2022.

BACKGROUND: Ischemic post-conditioning (IPoC) has been shown to improve outcomes in limited pre-clinical models. As down-time is often unknown, this technique needs to be investigated over a range of scenarios. As this tool limits reperfusion injury, there may be limited benefit or even harm after short arrest and limited ischemia-reperfusion injury.
METHODS: Eighteen male Wistar rats underwent 7 min of asphyxial arrest. Animals randomized to IPoC received a 20 s pause followed by 20 s of compressions, repeated four times, initiated 40 s into cardiopulmonary resuscitation. If return of spontaneous circulation (ROSC) was achieved, epinephrine was titrated to mean arterial pressure (MAP) of 70 mmHg. Data were analyzed using t-test or Mann-Whitney test. Significance set at p ≤ 0.05.
RESULTS: The rate of ROSC was equivalent in both groups, 88%. There was no statistically significant difference in time to ROSC, epinephrine required post ROSC, carotid flow, or peak lactate at any timepoint. There was a significantly elevated MAP with IPoC, 90.7 mmHg (SD 13.9), as compared to standard CPR, 76.7 mmHg (8.5), 2 h after ROSC, p = 0.03.
CONCLUSIONS: IPoC demonstrated no harm in a model of short arrest using a new arrest etiology for CPR based IPoC intervention in a rat model.

UNASSIGNED: Poor knowledge of Basic Life Support (BLS) can lead to hesitation in delivering prompt intervention, thus increasing mortality in people with cardiac arrest. We set out to determine level of knowledge of Basic Life Support among doctors and nurses working in a teaching hospital in Nigeria.
UNASSIGNED: Self-administered questionnaires were employed in a descriptive, cross-sectional study to assess knowledge of doctors and nurses. The overall knowledge score and, separate scores for doctors and nurses were calculated. Data was analyzed using IBM SPSS version 20.
UNASSIGNED: Two hundred and fifty participants (18-59) years were evaluated. There were more females (153, 61.2%) and more nurses (149, 59.8%). Sixty (24%) of the participants had received at least one previous BLS training. One hundred and one (40.4%) participants scored ≥50%. The overall average score was 43.6%. The average score for doctors and nurses were 45.1% and 42.7% respectively. Knowledge in some domains were very low viz: sequence in cardiopulmonary resuscitation (2.8%), compression-to-breath ratio (2.8%) and compression rate (32.3%). There was no significant difference in knowledge score by profession, gender, previous exposure to BLS training, number of years post-qualified and number of years in service.
UNASSIGNED: Healthcare workers in Nigeria have poor knowledge of BLS. They require training and re-training in BLS via creative and innovative means that are best suited for resource poor countries.

UNASSIGNED: To evaluate the effectiveness of Rapid Cycle Deliberate Practice (RCDP) compared to traditional instruction or other forms of learning on resuscitation training outcomes and on clinical and/or patient-related outcomes.
UNASSIGNED: As part of the continuous evidence evaluation process of the International Liaison Committee on Resuscitation it was conducted this review and searched Medline, Embase and Cochrane from inception to Feb 12th, 2024. Risk of bias assessment was performed with the Risk of Bias in Non-randomized Studies of Interventions assessment tool and the Revised Cochrane risk-of-bias tool for randomized trials. The GRADE approach was used to evaluate the overall certainty of evidence for each outcome.
UNASSIGNED: 4420 abstracts were retrieved by the initial search and 10 additional studies were identified through other resources. Sixty-five studies were selected for eligibility and nine simulated studies met the inclusion criteria. A meta-analysis was performed on three outcomes: time to chest compressions, time to defibrillation and time to first epinephrine given, which showed that RCDP had significantly shorter time to defibrillation and time to administration of epinephrine than controls. The overall certainty of evidence was very low across all outcomes due to risk of bias, inconsistency, indirectness, and imprecision.
UNASSIGNED: It may be reasonable to include RCDP as an instructional design feature of basic and advanced life support training. However, substantial variations of delivering RCDP exist and there is no uniform use of RCDP. Further research is necessary on medium/long-term effects of RCDP training, and on the effects on different target groups of training.

BACKGROUND: Performing CPR (Cardiopulmonary Resuscitation) is an extremely intricate skill whose success depends largely on the level of knowledge and skill of Anesthesiology students. Therefore, this research was conducted to compare the effect of the scenario-based training method as opposed to video training method on nurse anesthesia students\' BLS (Basic Life Support) knowledge and skills.
METHODS: This randomized quasi-experimental study involved 45 nurse anesthesia students of Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran in 2022-2023. The practical room of the university formed the research environment. The participants were randomly divided into three groups of scenario-based training, video training, and control. Data were collected by a knowledge questionnaire and a BLS skill assessment checklist before and after the intervention.
RESULTS: There was a significant difference between the students\' scores of BLS knowledge and skill before and after the educational intervention in both SG (scenario group) (p < 0.001) and VG (video group) (p = 0.008) (p < 0.001). However, no significant difference was observed in this regard in the CG (control group) (p = 0.37) (p = 0.16). Also, the mean scores of BLS knowledge and skills in the SG were higher than those in the VG (p < 0.001).
CONCLUSIONS: Given the beneficial impact of scenario-based education on fostering active participation, critical thinking, utilization of intellectual abilities, and learner creativity, it appears that this approach holds an advantage over video training, particularly when it comes to teaching crucial subjects like Basic Life Support.

UNASSIGNED: To explore literature, policies or procedures available to care providers on how to deliver CPR and BLS to people with a disability, for whom the current standard guidelines are not fit for purpose.
UNASSIGNED: A scoping review was conducted using four databases, namely, CINHAL, PubMed, Scopus, Medline and Google Scholar. Keywords used included, disab*, wheelchairs, cardiopulmonary, resuscitation, \"basic life support\", life support care, and bystander CPR. 1119 papers were retrieved and 1043 were screened following removal of 76 for duplication. 18 full text articles were reviewed and 5 met the inclusion criteria.
UNASSIGNED: The five articles were from three counties and included one case study, three expert opinion papers and one intervention study. Four of the papers advocated in favour of improved CPR and BLS guidelines and three of the papers discussed techniques and ideas for supplementation of standard CPR and BLS.
UNASSIGNED: The scoping review has uncovered a paucity of evidence explaining delivery of CPR and BLS for people with disability and highlights the need for further research. In the absence of further evidence, it is reasonable for educators to provide ideas and discussion about supplementing CPR and BLS for people with disability to carers.
People with disability and wheelchair users are at a high risk for premature or preventable deaths.Improved first aid responses are proposed to be a mitigating factor for premature and preventable deaths.Improved first aid responses will afford people with disability and wheelchair users the same opportunities for care and rehabilitation as people without disability.Formal and informal carers do not currently have prescriptive guidelines to improve their knowledge on responding to emergency events for people with disabilities.Development of improved guidelines is recommended to reduce fear and anxiety for formal and informal carers whilst also increasing their confidence to respond to emergency situations.

UNASSIGNED: A defibrillator should be connected to all patients receiving cardiopulmonary resuscitation (CPR) to allow early defibrillation. The defibrillator will collect signal data such as the electrocardiogram (ECG), thoracic impedance and end-tidal CO2, which allows for research on how patients demonstrate different responses to CPR. The aim of this review is to give an overview of methodological challenges and opportunities in using defibrillator data for research.
UNASSIGNED: The successful collection of defibrillator files has several challenges. There is no scientific standard on how to store such data, which have resulted in several proprietary industrial solutions. The data needs to be exported to a software environment where signal filtering and classifications of ECG rhythms can be performed. This may be automated using different algorithms and artificial intelligence (AI). The patient can be classified being in ventricular fibrillation or -tachycardia, asystole, pulseless electrical activity or having obtained return of spontaneous circulation. How this dynamic response is time-dependent and related to covariates can be handled in several ways. These include Aalen\'s linear model, Weibull regression and joint models.
UNASSIGNED: The vast amount of signal data from defibrillator represents promising opportunities for the use of AI and statistical analysis to assess patient response to CPR. This may provide an epidemiologic basis to improve resuscitation guidelines and give more individualized care. We suggest that an international working party is initiated to facilitate a discussion on how open formats for defibrillator data can be accomplished, that obligates industrial partners to further develop their current technological solutions.

Introduction: The performance of bystander cardiopulmonary resuscitation (CPR) improves survival among cardiac arrest victims. Near-peer teaching of Basic Life Support (BLS) may be an effective way to deliver resuscitation education. This article aims to assess the effectiveness of a student pharmacist-led American Heart Association (AHA) BLS course on high school students\' knowledge and skill achievement. Methods: Student pharmacists were trained as AHA instructors and delivered BLS certification courses to high school students. Participants completed pre- and post-assessments adapted from the course learning objectives. Skills performance was evaluated using the AHA\'s standardized forms. Participants completed questions regarding their perceptions of the pharmacist\'s role in BLS and confidence in pursuing a career in healthcare. Results: There were 321 participants with the majority in 11th or 12th grade (86.6%) and attending public school (99.1%). After completing the training, the mean percentage of correct assessment responses increased from 41.2% to 89% (p <0.0001). All participants correctly performed BLS skills. Most participants strongly agreed or agreed that the course changed their perspective of the pharmacist\'s role during BLS (74.8%) and increased their confidence in their decision to pursue future careers in healthcare (61.7%). Conclusion: Student pharmacist-led BLS training, using near-peer delivery, improves high school students\' knowledge and skill achievement. This strategy promotes high school students\' positive perceptions regarding pharmacists and their role in BLS, as well as their confidence in pursuing careers in healthcare.

To elucidate the relationship between the interval from cardiopulmonary resuscitation initiation to return of spontaneous circulation (ROSC) and neurologically favourable 1-month survival in order to determine the appropriate duration of basic life support (BLS) without advanced interventions. This population-based cohort study included patients aged ≥ 18 years with 9132 out-of-hospital cardiac arrest of presumed cardiac origin who were bystander-witnessed and had achieved ROSC between 2018 and 2020. Patients were classified into two groups based on the resuscitation methods as the \"BLS-only\" and the \"BLS with administered epinephrine (BLS-AE)\" groups. Receiver operating characteristic (ROC) curve analysis indicated that administering BLS for 9 min yielded the best neurologically outcome for patients with a shockable rhythm [sensitivity, 0.42; specificity, 0.27; area under the ROC curve (AUC), 0.60] in the BLS-only group. Contrastingly, for patients with a non-shockable rhythm, performing BLS for 6 min yielded the best neurologically outcome (sensitivity, 0.65; specificity, 0.43; AUC, 0.63). After propensity score matching, multivariate analysis revealed that BLS-only resuscitation [6.44 (5.34-7.77)] was associated with neurologically favourable 1-month survival. This retrospective study revealed that BLS-only intervention had a significant impact in the initial minutes following CPR initiation. Nevertheless, its effectiveness markedly declined thereafter. The optimal duration for effective BLS-only intervention varied depending on the patient\'s initial rhythm. Consequently, advanced interventions should be administered within the first few minutes to counteract the diminishing effectiveness of BLS-only intervention.
