Advancing Drowning Prevention

Background
Every year, drowning claims approximately 236,000 lives worldwide, as reported by the World Health Organization. Recognizing drowning as a preventable public health issue, the United Nations and WHO have prioritised the development of effective water safety interventions. Leeds Trinity University embarked on groundbreaking research to understand buoyancy variations among individuals and how these differences can influence drowning risk.
The Challenge: Enhancing Buoyancy Understanding Without Traditional Constraints
Traditional buoyancy assessment methods, such as hydrostatic weighing and tuck float tests, are invasive and unpleasant, presenting significant health and safety risks.
Leeds Trinity University sought a non-invasive, precise alternative to study buoyancy, which is crucial for developing effective self-rescue water safety skills.
The Solution: Artec 3D Scanning Technology
Central Scanning provided Leeds Trinity University with the Artec Eva handheld scanner and Artec Studio software, enabling precise, non-invasive measurement of body volume distribution. This technology choice was inspired by Dr. Arthur Stewart’s research on offshore workers’ buoyancy, suggesting that detailed 3D body scans could offer valuable insights into individual flotation characteristics without the need for water immersion.
Process: Detailed Body Scanning for Accurate Data Collection
The research team, facilitated by Central Scanning’s technology, conducted detailed scans of 24 participants, each in minimal swimwear to reduce extraneous variables. These participants were scanned in various poses and lung volumes to simulate real-life scenarios where floating could be a life-saving skill. The project involved meticulous planning and execution, ensuring high-quality data capture for subsequent analysis.
Using the Artec Eva, the team performed four full-body scans per participant, adjusting for different lung volumes to simulate real-life drowning scenarios. This process resulted in 96 comprehensive body scans, which were then processed using Artec Studio. The software’s sophisticated measurement tools allowed researchers to calculate total and segmental body volumes precisely.
The scans initially produced vertical (anatomical) 3D models. To simulate the advised back-floating position, these models were converted into horizontal orientations using advanced animation software, then re-imported into Artec Studio for further analysis. This innovative approach enabled the team to measure respiratory airway freeboard – the critical distance of the mouth and nose from the water surface.
Outcome: Pioneering Advances in Drowning Prevention Research
Future Directions
The findings are being prepared for publication, with the potential to influence global water safety practices profoundly. The research was presented at an international drowning prevention conference, highlighting its significance. Central Scanning extends heartfelt thanks to Leeds Trinity University, the research participants, and all involved teams for their dedication and hard work.
