Drowning literature have highlighted the submersion time as the most powerful predictor in assessing the prognosis. Reducing the time taken to provide a flotation device and prevent submersion appears of paramount importance. Unmanned aerial vehicles (UAVs) can provide the location of the swimmer and a flotation device.
The objective of this simulation study was to evaluate the efficiency of a UAV in providing a flotation device in different sea conditions, and to compare the times taken by rescue operations with and without a UAV (standard vs UAV intervention). Several comparisons were made using professional lifeguards acting as simulated victims. A specifically-shaped UAV was used to allow us to drop an inflatable life buoy into the water.
During the summer of 2017, 28 tests were performed. UAV use was associated with a reduction of time it took to provide a flotation device to the simulated victim compared with standard rescue operations (p < 0.001 for all measurements) and the time was reduced even further in moderate (81 ± 39 vs 179 ± 78 s; p < 0.001) and rough sea conditions (99 ± 34 vs 198 ± 130 s; p < 0.001). The times taken for UAV to locate the simulated victim, identify them and drop the life buoy were not altered by the weather conditions.
UAV can deliver a flotation device to a swimmer safely and quickly. The addition of a UAV in rescue operations could improve the quality and speed of first aid while keeping lifeguards away from dangerous sea conditions.
溺水文献强调了浸水时间是评估预后的最有力预测因素。减少提供漂浮装置和防止浸水所需的时间似乎至关重要。无人驾驶飞行器 (UAV) 可以提供游泳者的位置和漂浮装置。
本模拟研究的目的是评估 UAV 在不同海况下提供漂浮装置的效率，并比较有无 UAV（标准与 UAV 干预）的救援行动所花费的时间。使用专业救生员作为模拟受害者进行了多次比较。使用特定形状的 UAV 可以让我们将充气救生圈投入水中。
在 2017 年夏天，进行了 28 次测试。与标准救援行动相比，UAV 的使用与提供漂浮装置给模拟受害者的时间缩短有关（所有测量均为 p < 0.001），并且在中度（81 ± 39 与 179 ± 78 s；p < 0.001）和波涛汹涌的海况下（99 ± 34 与 198 ± 130 s；p < 0.001）进一步缩短了时间。UAV 找到模拟受害者、识别他们并放下救生圈的时间不受天气条件的影响。
UAV 可以安全快速地将漂浮装置送到游泳者手中。在救援行动中增加 UAV 可以提高急救的质量和速度，同时使救生员远离危险的海况。
