Health-related quality of life, teachers’ opinion of academic performance and self-perceived health are indicators of well-being in the adolescent stage. Some variables, such as those related to the quality of family and parental relationships, may influence these indicators and thus condition well-being during this stage of life and beyond. In this research, the aforementioned variables are analyzed jointly. It is a cross-sectional study in which 1375 adolescent schoolchildren between 11 and 18 years of age participated. Different instruments such as KIDSCREEN-10 and the questionnaire used in the international study Health Behaviour in School-Aged Children were used. The results obtained allow us to conclude that HRQoL, the teacher’s opinion of performance and the perception of health status improve as adolescents perceive a more favorable family climate, also helped by good relations between parents. Finally, it is proposed to continue with the efforts made in the school, family environment and other areas because of the enormous potential for generating quality of life in the adolescent stage and the consequent positive repercussions this has on adulthood.

The aim of this study was to evaluate the knowledge of first aid (FA) of primary and pre-school teachers and the parents of children in these education stages. A questionnaire already used in previous publications was employed and consisted of 4 sections: 1) general information; 2) assessment of FA knowledge; 3) questions about FA, and 4) attitudes about FA. The questionnaire was sent by e-mail in Google Forms format to different education centres of the Autonomous Community of Galicia. The centres were asked to send them to the school staff and parents of the pupils so that they could be completed. A total of 470 questionnaires were analysed (177 teachers; 242 parents and 51 teachers with children). More than half (268, 57%) of the participants stated to have knowledge of FA. In the case of the teachers, a relationship was found between having this information and teaching these contained in the classroom (P=.008). Only 4 participants managed to arrange the basic life support sequence, and none of them correctly answered the questions on cardiopulmonary resuscitation. More than 95% of the sample considered it necessary to include FA in the school curriculum and in the study plans of degrees destined for teacher training. The majority of teachers and parents had training in FA, although none of them responded correctly to the questions related to basic life support. The inclusion of these contents in school curricula would be recommendable, but it requires training the teaching staff beforehand. The inclusion of these contents in university study plans should be a measure to take into account.

Purpose Drowning is a high-priority public health problem around the world. The European Resuscitation Council Guidelines for Resuscitation 2015 put special emphasis on special environments like open waters. Stopping the drowning process as soon as possible and starting an early cardiopulmonary resuscitation (CPR) improve survival. Inflatable rescue boats (IRBs) are used around the world in the water rescue of drowning victims. Our objective was to test the quality of CPR performed by surf-lifeguards while sailing on an IRB. Methods A quasi-experimental simulation trial was conducted in Tenerife (Canary Islands—Spain) on September 2015. Ten surf-lifeguards were asked to perform a 2 min CPR on manikins in four different scenarios: (1) onshore, (2) on adrift boat, (3) on a boat sailing at 5 knots and (4) on a boat sailing at 10 knots. CPR was performed individually and was measured by means of CPRmeter (Laerdal, Norway) located on the standard manikin. Repeated measures analysis of variance was used in order to analyse the differences between scenarios. Results The composite of all CPR variables was over 84% in all conditions, but it was lower when CPR was performed on board: onshore (96.49±3.58%) versus adrift (91.80±3.56, p=0.04), sailing at 5 knots (88.65±5.54, p=0.03) and sailing at 10 knots (84.74±5.56, p=0.001). Conclusion Surf-lifeguards are able to deliver good-quality CPR even on a moving IRB, but their performance is lower than onshore. This fact should be considered in real cases to balance the risk and benefits of CPR on board.

Background: Providing high-quality chest compressions and rescue breaths are key elements in the effectiveness of cardio­pulmonary resuscitation. Aim: To investigate the effects of a strength training programme on the quality of prolonged basic cardiopulmonary resuscitation on a manikin. Methods: This was a quasi-experimental trial. Thirty-nine participants with prior basic life support knowledge were randomised to an experimental or control group. They then performed a test of 10 min of chest compressions and mouth-to-mouth ventilation on manikins equipped with a skill reporter tool (baseline or test 1). The experimental group participated in a four-week strength training programme focused on the muscles involved in chest compressions. Both groups were subsequently tested again (test 2). Results: After training, the experimental group significantly increased the mean depth of compression (53.7 ± 2.3 mm vs. 49.9 ± 5.9 mm; p = 0.003) and the correct compression fraction (68.2 ± 21.0% vs. 46.4 ± 29.1%; p = 0.004). Trained subjects maintained chest compression quality over time better than the control group. The mean tidal volume delivered was higher in the experimental than in the control group (701.5 ± 187.0 mL vs. 584.8 ± 113.6 mL; p = 0.040) and above the current resuscitation guidelines. In test 2, the percentage of rescue breaths with excessive volume was higher in the experi­mental group than in the controls (31.5 ± 19.6% vs. 15.6 ± 13.0%; p = 0.007). Conclusions: A simple strength training programme has a significant impact on the quality of chest compressions and its maintenance over time. Additional training is needed to avoid over-ventilation of potential patients.
