Lifeguard

Coastal environments present dynamic challenges necessitating rapid and efficient responses during aquatic emergencies. Lifeguards, as pivotal links in the intervention chain, rely on various tools, with rescue time being paramount. The choice of fins, specifically long versus short ones, plays a critical role in optimizing lifeguard performance during rescues. This randomized cross-over study explores the impact of flipper size on ocean rescues, employing a sample of 14 lifeguards. Long fins (LFs) and short fins (SFs) were compared in terms of rescue time (RT) and physiological load (PL)...

INTRODUCTION: Current literature on stingray envenomations focuses on the incidence, presentation, and complications of these injuries, with some studies providing such data for specific geographic locations. This is the first study to evaluate the influence of environmental factors and human characteristics on stingray envenomation patterns in San Diego, California. METHODS: Incident reports of injuries documented by the San Diego Fire-Rescue Department/Lifeguard Division (SDFR-LG) during 2017 were analyzed...

BACKGROUND: The development of skin cancer is closely related to high exposure to UV radiation. Lifeguards are at an increased risk of excessive sun exposure. Objectives The main objective of this study was to measure the exposure of Barcelona's beach lifeguards to UV radiation. METHODS: Measurements in the work chair were taken every 30 minutes on a typical working day from 10:45 am to 19:15 pm. These measurements were carried out on four different days. These data were used to calculate the erythematous doses received during working hours, as well as those potentially received throughout the summer season...

(1) Objective: The objective was to evaluate the quality of cardiopulmonary resuscitation (CPR, chest compressions and ventilations) when performed by a lone first responder on an infant victim via the over-the-head technique (OTH) with bag-mask ventilation in comparison with the standard lateral technique (LAT) position. (2) Methods: A randomized simulation crossover study in a baby manikin was conducted. A total of 28 first responders performed each of the techniques in two separate CPR tests (15:2 chest compressions:ventilations ratio), each lasting 5 min with a 15 min resting period...

INTRODUCTION: In recent years, climate change and human activity have modified marine biotopes, including the widening distribution of harmful algal blooms (HABs). Bloom events predominated by microalgae of the genus Ostreopsis have been described on the French Mediterranean coast, but in 2021 an unprecedented bloom occurred on the French Basque coast. The objective of this study is to describe the health impact of the Ostreopsis spp bloom that occurred on the French Basque coast in 2021...

BACKGROUND: A technique called in-water resuscitation (IWR) was devised on a surfboard to ventilate persons who seemingly did not breathe upon a water rescue. Despite IWR still raises uncertainties regarding its applicability, this technique is recommended by the International Liaison Committee for Resuscitation (ILCOR). Thus, this study aimed to evaluate the feasibility of IWR with a rescue board before and during towing and, to compare rescue times and rescue-associated fatigue levels between rescues with rescue breath attempts and without (SR)...

INTRODUCTION: Control of massive hemorrhage (MH) is a life-saving intervention. The use of tourniquets has been studied in prehospital and battlefield settings but not in aquatic environments. OBJECTIVE: The aim of this research is to assess the control of MH in an aquatic environment by analyzing the usability of two tourniquet models with different adjustment mechanisms: windlass rod versus ratchet. METHODOLOGY: A pilot simulation study was conducted using a randomized crossover design to assess the control of MH resulting from an upper extremity arterial perforation in an aquatic setting...

BACKGROUND: Challenging situations in clinical practice negatively affect nursing students' perceptions of the nursing profession and their professional learning and development. DESIGN: The study is based on quantitative, metaphorical and picture-drawing analysis...

Drowning remains a prominent global pediatric health concern, necessitating preventive measures such as educational initiatives for children and caregivers. In this study, we aimed to assess the feasibility and educational effectiveness of an interactive puppet show centered on teaching water safety to children and parents. A 30 min original theater performance, featuring two actors and three puppets (a girl, a crab, and a lifeguard), was conducted. Subsequently, 185 children (aged 4 to 8) and their 160 parents (134 mothers and 26 fathers) participated in this quasi-experimental study...

Soil sampling for environmental DNA in remote and semi-remote locations is often limited due to logistical constraints surrounding sample preservation, including no or limited access to a freezer. Freezing at - 20 °C is a common DNA preservation strategy, however, other methods such as desiccation, ethanol or commercial preservatives are available as potential alternative DNA preservation methods for room temperature storage. In this study, we assessed five preservation methods (CD1 solution, 95% Ethanol, Dry & Dry silica gel packs, RNAlater, LifeGuard) along with freezing at - 20 °C, against immediate extraction on organic and mineral soils for up to three weeks of preservation...

OBJECTIVE: The Los Angeles County Fire Department Lifeguard Division responds to water rescues and medical and dive emergencies across 72 miles of Southern California coastline and Catalina Island. Limited advanced life support resources make cardiac arrest resuscitations logistically challenging during transport to shore or the hyperbaric chamber. This proof-of-concept study looked to determine if an i-Gel (Intersurgical Complete Respiratory Systems, Wokingham, Berkshire, UK) supraglottic airway device would either become dislodged or compromise ventilations during prolonged resuscitation at high speeds over open water with an ongoing automatic chest compression device (ACCD)...

INTRODUCTION: Lifeguards must maintain alertness and monitor an aquatic space across extended periods. However, lifeguard research has yet to investigate a lifeguard's ability to maintain performance over time and whether this is influenced by years of certified experience or the detection difficulty of a drowning incident. The aim of this study was to examine whether lifeguard experience, drowning duration, bather number, and time on task influences drowning detection performance. METHOD: A total of 30 participants took part in nine 60-minute lifeguard specific tasks that included 11 drowning events occurring at five-minute intervals...

BACKGROUND: Surfers play a critical role in coastal drowning prevention, conservatively estimated to make as many rescues as beach lifeguards. The Surfer Rescue 24/7 (SR24/7) program is a coastal safety intervention in Australia and New Zealand that teaches surfers safe rescue skills and promotes prevention activities. This multi-part, mixed-methods study aimed to evaluate the impact of the SR24/7 program. METHODS: The study consisted of three parts employing quantitative and qualitative methods: a retrospective survey of course participants, in-depth interviews with course participants who had conducted rescues, and an analysis of self-reported skills confidence ratings before and after the program...

According to the International Life Saving Federation (ILS), integrating lifeguards in the local or regional emergency medical service (EMS) is a necessity to prevent drowning and improve prehospital treatment in selected situations. This review describes the organisation of lifeguards in Denmark, focusing on essential skills and equipment to assist prehospital EMS in drowning, out-of-hospital cardiac arrest, and search and rescue operations. Standardised requirements for the medical education of lifeguards are warranted to improve prehospital treatment and integration in the EMS...

Surfing is a globally popular recreational sport with limited epidemiologic data. Currently, there is a paucity of literature regarding injury profiles and mechanisms of orthopaedic-related injuries. This study analyzed trends, etiologies, and diagnoses of upper extremity orthopaedic-related surfing injuries presenting to United States (US) emergency departments. The National Electronic Injury Surveillance System database was accessed to query upper extremity surfing-related injuries presenting to US emergency departments from January 1, 2002 to December 31, 2021...

Sun exposure is harmful to the skin and increases the risk of skin aging and skin cancer. Here we examined the effects of daily exposure to sun radiation on the skin microbiome in order to determine whether skim microbiome bacteria can contribute to protection from solar damage. Skin swabs were collected from ten lifeguards before and after the summer to analyse the skin microbiome. The results indicates that specific skin microbiome bacteria were enriched following the seasonal sun exposure. Especially interesting were two bacterial families - Sphingomonas and Erythrobacteraceae - which may have the ability to protect against UV radiation as they produce potentially protective compounds...

The aim of this study was to compare the quality of standard infant CPR with CPR in motion (i.e., walking and running) via performing maneuvers and evacuating the infant from a beach. Thirteen trained lifeguards participated in a randomized crossover study. Each rescuer individually performed three tests of 2 min each. Five rescue breaths and cycles of 30 chest compressions followed by two breaths were performed. Mouth-to-mouth-and-nose ventilation was carried out, and chest compressions were performed using the two-fingers technique...

Flooding is a significant cause of human and economic loss in the African region, including in South Africa. Flood mitigation and response in South Africa is challenging due to a range of environmental, infrastructure, and policy constraints. Lifeguards represent a potential additional workforce to bolster flood mitigation and response. This study aimed to explore the feasibility and acceptability of online flood safety training for water safety professionals in South Africa, as well as assess the current flood response capacity and future needs of this group...

BACKGROUND: Rip currents are strong, narrow, fast-flowing currents of water that occur on many beaches and in Australia contributing to 26 drowning deaths and several thousand lifeguard/lifesaver rescues each year. Educating the public about the rip current hazard is a primary focus of beach safety practitioners, but there has been a lack of qualitative research exploring the firsthand experiences of being caught in a rip current to assist in this regard. The aim of this study was to analyse interviews of rip current survivors to understand more about how people react when unintentionally caught in a rip current in order to help guide future public education to mitigate rip current drowning...
