ABCDE approach to victims by lifeguards: How do they manage a critical patient? A cross sectional simulation study.

INTRODUCTION: Decision-making in emergencies is a multifactorial process based on the rescuer, patient, setting and resources. The eye-tracking system is a proven method for assessing decision-making processes that have been used in different fields of science. Our aim was to evaluate the lifeguards' capacity to perform the ABCDE (Airway-Breathing-Circulation-Disability-Exposure) approach when facing a simulated critically ill-drowned victim. METHODS: A cross-sectional simulation study was designed to assess the skills and sequence of the ABCDE approach by 20 professional lifeguards. They had to assess a victim and act according to his/her clinical status by following the ABCDE primary assessment approach. The two kinds of variables were recorder: those related to the quality of each step of the ABCDE approach and the visual behaviour using a portable eye-movement system. The eye-tracking system was the Mobile Eye system (Bedford, USA). RESULTS: None of the study participants were able to complete correctly the ABCDE approach. Lifeguards spent more time in the Circulation step: Airway (15.5±11.1 s), Breathing (25.1±21.1 s), Circulation (44.6±29.5 s), Disability (38.5±0.7 s). Participants spent more time in viewpoints considered as important (65.5±17.4 s) compared with secondary ones (34.6±17.4 s, p = 0.008). This was also represented in the percentage of visual fixations (fixations in important viewpoints: 63.36±15.06; fixation in secondary viewpoints: 36.64±15.06; p = 0.008). CONCLUSION: Professional lifeguards failed to fully perform the ABCDE sequence. Evaluation by experts with the help of eye-tracking technology detected the lifeguards' limitations in the assessment and treatment of an eventual critically ill victim. Such deficits should be considered in the design and implementation of lifeguards' training programmes.

Psychomotor Limitations of Overweight and Obese Five-Year-Old Children: Influence of Body Mass Indices on Motor, Perceptual, and Social-Emotional Skills.

The present research aimed to study the psycho-motor performance of five-year-old children with different body mass indices (BMI). A total of 694 pre-school children in the province of Albacete-Spain participated. Their performance in motor, perceptual, and social-emotional skills was analyzed using a standardized observation sheet (Checklist of Psychomotor Activities-CPA) and then compared according to their BMI using non-parametric statistical methods (Mann-Whitney test). Separate comparisons were made for girls and boys. Results indicated significant differences in performance amongst the groups of girls in all the motor and perceptual activities, and in the social relationships component of the social-emotional factor. These differences seemed to penalize motor activities, perceptual skills, and social relationships in overweight and obese girls compared to normal weight girls. In the case of boys, there were significant differences in laterality and visual-motor coordination (favoring overweight boys). Differences in respiratory control were also found, but in this case, penalizing obese boys compared to normal weight boys. Knowledge of possible psychomotor limitations in obese children could allow psychologists and healthcare professionals to design more focused interventions.

Learning and Treatment of Anaphylaxis by Laypeople: A Simulation Study Using Pupilar Technology.

An anaphylactic shock is a time-critical emergency situation. The decision-making during emergencies is an important responsibility but difficult to study. Eye-tracking technology allows us to identify visual patterns involved in the decision-making. The aim of this pilot study was to evaluate two training models for the recognition and treatment of anaphylaxis by laypeople, based on expert assessment and eye-tracking technology. A cross-sectional quasi-experimental simulation study was made to evaluate the identification and treatment of anaphylaxis. 50 subjects were randomly assigned to four groups: three groups watching different training videos with content supervised by sanitary personnel and one control group who received face-to-face training during paediatric practice. To evaluate the learning, a simulation scenario represented by an anaphylaxis' victim was designed. A device capturing eye movement as well as expert valuation was used to evaluate the performance. The subjects that underwent paediatric face-to-face training achieved better and faster recognition of the anaphylaxis. They also used the adrenaline injector with better precision and less mistakes, and they needed a smaller number of visual fixations to recognise the anaphylaxis and to make the decision to inject epinephrine. Analysing the different video formats, mixed results were obtained. Therefore, they should be tested to evaluate their usability before implementation.

El comportamiento visual de bloqueadoras juveniles de voleibol y su relación con la precisión de su respuesta / / Comportamento visual dos juvenis de bloqueio voleibol e sua relação com a precisão de sua resposta / Visual behaviour of youth volleyball blockers and its relationship with their response accuracy

El presente estudio examina el comportamiento visual de jóvenes jugadoras de voleibol en la acción del bloqueo. El objetivo fue analizar las estrategias de búsqueda visual y las principales localizaciones de las fijaciones en el transcurso de la acción, estableciendo relaciones entre éstas y el porcentaje de aciertos. 29 jugadoras de voleibol (17,4 ± 0,9 años de edad) debían decidir la dirección de la colocación durante la visualización de secuencias de vídeo proyectadas a tamaño real. Se registraba su decisión mediante el movimiento de las jugadoras, que fue grabado por una cámara de vídeo a 25 fps y se analizó fotograma a fotograma. El comportamiento visual de las jugadoras se obtuvo mediante un sistema de seguimiento de la mirada (Mobile Eye de ASL), y se analizó en función de las dos direcciones de la colocación: zona 3 y zona 4. Se calculó el coeficiente de correlación de Pearson entre el Porcentaje de aciertos totales y las diferentes variables de comportamiento visual, y se aplicó la estadística inferencial para comprobar las diferencias en función de la zona. Las jugadoras estaban más sincronizadas con la información relativa al balón que con la contenida en la colocadora, siendo esa la fuente de información en la que principalmente basaron sus decisiones. La fijación de la zona Balón-Muñeca en los momentos cercanos al contacto puede ser la clave para lograr una correcta anticipación en esta acción, ya que permitiría extraer información del balón y del brazo de la colocadora al mismo tiempo mediante la visión periférica (AU)

The present study examines the visual behavior of young volleyball players during block action. The aim was to analyze visual search behaviour and the main locations during the action, establishing relationships between them and the percentage of correct answers.29 female volleyball players (17,4 ± 0,9 years old) should decide the direction of the setting while the viewed video sequences projected in actual size. The players registered their decision through their movement, which was recorded by a video camera at 25 fps and analyzed frame by frame. Visual behavior of the players is obtained through a system of eye tracking (ASL Mobile Eye), and analyzed according to the two different ball destinations: Zone 3 and Zone 4. Pearson correlation coefficient was calculated between the percentage of total hits and the different variables of visual behavior, and inferential statistics were applied to test for differences depending on the area. Players were more attuned to the information on the ball with that contained in the setter, and this is the source of information on which they based their decisions primarily. Fixing the ball-wrist area in early contact times may be the key to a correct anticipation in this action, as it would allow extracting information of the ball and the arm of the setter while using peripheral vision (AU)
