ABSTRACT
Tasks performed by search and rescue (SAR) teams can be physically demanding. SAR organizations are faced with mounting challenges due to increased participation in recreation in remote locations and more frequent extreme weather. We sought to describe the physiological response and the methods for data collection during helicopter emergency medical service (HEMS) winch rescue from remote wilderness in extreme heat. A flight paramedic sustained 81% of maximum heart rate (VO₂ ~44.8 mL/kg/min) for ~10 minutes at a rate of perceived exertion of 19/20, and a relative heart rate of 77.5% in 37.1°C. Maximal acceptable work time for this task was calculated at 37.7 minutes. Our data collection methods were feasible, and the data captured demonstrated the level of physiological strain that may be encountered during HEMS SAR operations in austere environments and hot climate. It is essential that SAR teams that perform physically demanding tasks use a scientific approach to adapt and evolve. This is necessary to ensure personnel are appropriately selected, trained, and equipped to respond in an era of increasing demand and extreme environments.

ABSTRACT
Venezuela is living in a delicate social and political crisis that has taken thousands of lives. Beginning in March 2017, a series of continuous and increasingly violent demonstrations has taken place, with a high number of civilian casualties. These demonstrations typically have been outside the range of action of the government prehospital services. In addition, the number of casualties frequently overwhelmed the abilities of the available rescue services. Out of the need for a first aid team that could operate in this violent scenario, First Aid UCV (Central University of Venezuela) was created. A large number of professionals with medical, rescue, and tactical medicine experience integrated this new team, modifying their training and practice to adapt to a scenario in which unarmed medical students and medical doctors performed extractions, provided first aid, and managed the transport of demonstration casualties, doing so even when team members were sometimes targeted by the government police and military forces. This method has had successful results in all 60 operations conducted to date, with a total of 5,000 casualties being extracted among civilians, the military, and the police force. Only one member of the team was injured during the operations, and no deaths were reported during the process.

Impact of a 10,000-m Cold-Water Swim on Norwegian Naval Special Forces Recruits
Melau J, Hisdal J, Solberg PA. 21(3). 55 - 59. (Journal Article)
|
|
ABSTRACT
Background: Special Operation Forces (SOF) operate regularly in extreme environmental conditions that may affect tactical and physical performance. The main aims of the present study were to elucidate the impact of a long cold-water swim on SOF recruits' dexterity, performance, and reaction time. Material and Methods: Eleven recruits from Norwegian Naval Special Operation Command (NORNAVSOC) that were participating in a 10,000-m open water swim with a dry suit in 5°C cold water volunteered to participate in this study. The exercise was part of their training. Grip strength, lower body power, and dexterity were measured before, immediately after, and 24 hours after the swim. In addition, core and skin temperatures were measured continuously during the swim and until 45 minutes after the swim. Results: After the swim, moderate to large reductions in core temperature, lower body power, and reaction time were observed. Moreover, very large to extremely large reductions in skin temperature, grip strength, and dexterity were also observed. Conclusion: These results demonstrate that exposure to a 10,000-m swim in 5°C water using standard equipment led to a significant drop in the recruits' temperature and performance. These findings could have a meaningful impact on the planning of training, operations, and gear used for SOF.
