Previous pilot experience has shown the ability of visually impaired and blind people (BP) to learn basic life support (BLS), but no studies have compared their abilities with blindfolded people (BFP) after participating in the same instructor-led, real-time feedback training. Twenty-nine BP and 30 BFP participated in this quasi-experimental trial. Training consisted of a 1 h theoretical and practical training session with an additional 30 min afterwards, led by nurses with prior experience in BLS training of various collectives. Quantitative quality of chest compressions (CC), AED use and BLS sequence were evaluated by means of a simulation scenario. BP’s median time to start CC was less than 35 s. Global and specific components of CC quality were similar between groups, except for compression rate (BFP: 123.4 + 15.2 vs. BP: 110.8 + 15.3 CC/min; p = 0.002). Mean compression depth was below the recommended target in both groups, and optimal CC depth was achieved by 27.6% of blind and 23.3% of blindfolded people (p = 0.288). Time to discharge was significantly longer in BFP than BP (86.0 + 24.9 vs. 66.0 + 27.0 s; p = 0.004). Thus, after an adapted and short training program, blind people were revealed to have abilities comparable to those of blindfolded people in learning and performing the BLS sequence and CC.

To evaluate nursing students’ CPR skills using mouth-to-mouth (MMV) and bag-valve-mask (BMV) ventilation techniques on manikin simulators for infant and adult victims after practical and theoretical training. A quasi-experimental randomised cross-over design study with 44 nursing students was carried out. The participants attended a 5-hour theoretical and practical CPR training session using MMV and BMV on adult and infant manikins. A month later, four 4-minute CPR tests were performed in pairs. Two tests were performed on the infant manikin and two on the adult, using the two ventilation techniques (MMV and BMV). No significant differences between the tests were observed in the quality of chest compression (p > 0.008). Significantly higher values of effective ventilations were observed with MMV as compared with BMV in both age groups: Adult (MMV: 98 ± 7% / BMV: 84 ± 17% / p = 0.003) and Infant (MMV: 97 ± 11% / BMV: 76 ± 26% / p = 0.001). CPR quality was significantly higher when using MMV on the infant (68 ± 16%; p < 0.001) than in the other tests. The nursing students did not manage to master BMV with either victim. New complementary strategies to help them grasp the necessary BMV skills will be required.

Abstract Background The aim of this manikin study was to evaluate the quality of cardiopulmonary resuscitation (CPR) with restricted patient access during simulated avalanche rescue using over-the-head and straddle position as compared to standard position. Methods In this prospective, randomised cross-over study, 25 medical students (64% male, mean age 24) performed single-rescuer CPR with restricted patient access in over-the-head and straddle position using mouth-to-mouth ventilation or pocket mask ventilation. Chest compression depth, rate, hand position, recoil, compression/decompression ratio, hands-off times, tidal volume of ventilation and gastric insufflation were compared to CPR with unrestricted patient access in standard position. Results Only 28% of all tidal volumes conformed to the guidelines (400–800 ml), 59% were below 400 ml and 13% were above 800 ml. There was no significant difference in ventilation parameters when comparing standard to atypical rescuer positions. Participants performed sufficient chest compressions depth in 98.1%, a minimum rate in 94.7%, correct compression recoil in 43.8% and correct hand position in 97.3% with no difference between standard and atypical rescuer positions. In 36.9% hands-off times were longer than 9 s. Conclusions Efficacy of CPR from an atypical rescuer position with restricted patient access is comparable to CPR in standard rescuer position. Our data suggest to start basic life-support before complete extrication in order to reduce the duration of untreated cardiac arrest in avalanche rescue. Ventilation quality provided by lay rescuers may be a limiting factor in resuscitation situations where rescue ventilation is considered essential.

Several professional groups, which are not health professionals, are more likely to witness situations requiring basic life support (BLS) due to the nature of their job. The aim of this study was to assess BLS learning after 150 min of training in undergraduate students of sports science and their retention after eight months. Participants trained on BLS (150-min session: 30 theory, 120 practice). After training (T1) and after 8 months (T2), we evaluated their performance of the BLS sequence and two minutes of cardiopulmonary resuscitation (CPR). At T1, the 23 participants presented a mean score of 72.5 ± 21.0% in the quality of the CPRs (compressions: 78.6 ± 25.9%, ventilation: 69.9 ± 30.1%). More than 90% of the participants acted correctly in each step of the BLS sequence. At T2, although the overall quality of the CPR performed did not decrease, significant decreases were observed for: correct hand position (T1: 98.2 ± 8.8, T2: 77.2 ± 39.7%), compression depth (T1: 51.4 ± 7.9, T2: 56.0 ± 5.7 mm), and compression rate. They worsened opening the airway and checking for breathing. In conclusions, participants learned BLS and good-quality CPR after the 150-min training session. At eight months they had good retention of the BLS sequence and CPR skills. Training on airway management and the position of the hands during CPR should be reinforced.

: The acquisition of competencies in basic life support (BLS) among university students of health sciences requires specific and updated training; therefore, the aim of this review was to identify, evaluate, and synthesise the available scientific knowledge on the effect of training in cardiorespiratory resuscitation in this population. A comprehensive literature search was conducted in MEDLINE, CUIDEN, Web of Science, Wiley Online Library, CINAHL, and Cochrane, including all randomised clinical trials published in the last ten years that evaluated basic life support training methods among these students. We selected a total of 11 randomissed clinical trials that met the inclusion criteria. Participants were nursing and medicine students who received theoretical and practical training in basic life support. The studies showed a great heterogeneity in training methods and evaluators, as did the feedback devices used in the practical evaluations and in the measurement of quality of cardiorespiratory resuscitation. In spite of the variety of information resulting from the training methods in basic life support, we conclude that mannequins with voice-guided feedback proved to be more effective than the other resources analysed for learning.

Background: Out-of-hospital cardiac arrest is an important cause that leads to hospital admission and death. Improving lay people’s knowledge and skills in basic life support (BLS) may lead to reduced death associated with out-of-hospital cardiac arrest. “BLS NU KKU” is a BLS training program developed from up-to-date literature as a smartphone application used to train lay people in the community. Objective: To evaluate BLS-related knowledge and skills of participants before and after BLS training. Materials and Methods: A one group pretest-posttest design was used to implement the present study in Khon Kaen, Thailand. Participants were 350 individuals age 18 and older. An 8-hour BLS training session was offered to 10 groups of 35 participants over the period of 10 months between November 2018 and August 2019. Self-administered questionnaires were used to assess BLS knowledge and Cardiopulmonary resuscitation (CPR) skills. Results: The mean score for BLS-related knowledge significantly increased after the BLS training (mean = 15.05, SD = 2.51) compared to the scores before the training (mean = 10.47, SD = 3.43) (p<0.05). BLS skills improved from 0% to 100% (p<0.001) will all skills rated with mostly “excellent” and “good”. Satisfaction with the training program was also rated mostly with “excellent” and “good”. Conclusion: The BLS training program effectively improved participants’ knowledge and skills for basic life support. This program should be disseminated to train lay people in other settings.

Background Serious games enrich simulation-based health care trainings and improve knowledge, skills, and self-confidence of learners while entertaining them. Objective A platform which can combine performance data from a basic life support (BLS) serious game app and hands-on data based on the same scoring system is not available in the market. The aim of this study was to create such a platform and investigate whether performance evaluation of BLS trainings would be more objective compared to conventional Objective Structured Clinical Examination (OSCE) examinations if these evaluations were carried out with the platform which combines OSCE scoring criteria with sensor data retrieved from the simulator’s sensors. Methods Participants were 25 volunteers (11 men [44.0%] and 14 [56.0] women) among Acıbadem Mehmet Ali Aydınlar University students without prior knowledge of the BLS protocol. A serious game module has been created for teaching learners the European Resuscitation Council Basic Life Support 2015 protocol. A second module called the hands-on module was designed for educators. This module includes a checklist used for BLS OSCE examinations and can retrieve sensor data such as compression depth, compression frequency, and ventilation volume from the manikin (CPR Lilly; 3B Scientific GmbH) via Bluetooth. Data retrieved from the sensors of the manikin enable educators to evaluate learners in a more objective way. Performance data retrieved from the serious gaming module have been combined with the results of the hands-on module. Data acquired from the hands-on module have also been compared with the results of conventional OSCE scores of the participants, which were obtained by watching the videos of the same trainings. Results Participants were considered successful in the game if they scored 80/100 or above. Overall, participants scored 80 or above in an average of 1.4 (SD 0.65) trials. The average BLS serious game score was 88.3/100 (SD 5.17) and hands-on average score was 70.7/100 (SD 17.3), whereas the OSCE average score was 84.4/100 (SD 12.9). There was no statistically significant correlation between success on trials (score ≥80/100), serious game, hands-on training app, and OSCE scores (Spearman rho test, P>.05). The mean BLS serious game score of the participants was 88.3/100 (SD 5.17), whereas their mean hands-on training app score was 70.7/100 (SD 17.3) and OSCE score was 84.4/100 (SD 12.9). Conclusions Although scoring criteria for OSCE and hands-on training app were identical, OSCE scores were 17% higher than hands-on training app scores. After analyzing the difference of scores between hands-on training app and OSCE, it has been revealed that these differences originate from scoring parameters such as compression depth, compression frequency, and ventilation volume. These data suggest that evaluation of BLS trainings would be more objective if these evaluations were carried out with the modality, which combines visual OSCE scoring criteria with sensor data retrieved from the simulator’s sensors.

AIMS: To evaluate the learning retention of participants of a Basic Life Support course in a dental unit of a university hospital.METHODS: This study combined quantitative and qualitative methods in a quasi-experimental design, in which the same subjects were compared before and at two moments after an intervention, which consisted of a training course in Basic Life Support. The participants were employees of the Oral Health Unit of the University Hospital of Brasília. Three evaluations were performed: pre-test, post-test and late post-test, in order to assess participants' learning retention. In a second stage of the research, interviews were conducted with the participants approved in the retention learning test.RESULTS: At all, 66 professionals participated in the course and carried out the theoretical pre-test and the theoretical and practical post-test. One year and five months after the course, 10 participants were submitted to the late post-test, also theoretical and practical. Regarding the theoretical knowledge, the mean was 6.3±2.31 points in the pre-test, 8.3±1.25 points in the post-test and 5.1±1.44 points in the late post-test. Late post-test results revealed also that 70% of participants met the minimum theoretical knowledge requirement for approval (5 of 10 points) but only 20% passed the practical retention assessment. The two participants who passed the practical evaluation had repeated the training after the initial course.CONCLUSIONS: Basic Life Support training based on simulation resulted in practical and theoretical learning in cardiopulmonary resuscitation. However, the effect did not persist after one year and five months, except for participants who repeated the training during this period, indicating that the long term retention of this learning requires more opportunities for training or practice. Further studies are needed to investigate the ideal workload, the number of repetitions required during training and the appropriate frequency of training, as well as to obtain information about the influence of prior knowledge of the participants and the practice after training in retention of skills.
