Search and rescue (SAR) operations constitute a significant proportion of Norwegian ambulance helicopter missions, and they may limit the service's capacity for medical operations. We compared the relative contribution of the different helicopter resources using a common definition of SAR-operation in order to investigate how the SAR workload had changed over the last years.
We searched the mission databases at the relevant SAR and helicopter emergency medical service (HEMS) bases and the Joint Rescue Coordination Centre (North) for helicopter-supported SAR operations within the potential operation area of the Tromsø HEMS base in 2000-2010. We defined SAR operations as missions over land or sea within 10 nautical miles from the coast with an initial search phase, missions with use of rescue hoist or static rope, and avalanche operations.
There were 769 requests in 639 different SAR operations, and 600 missions were completed. The number increased during the study period, from 46 in 2000 to 77 in 2010. The Tromsø HEMS contributed with the highest number of missions and experienced the largest increase, from 10 % of the operations in 2000 to 50 % in 2010. Simple terrain and sea operations dominated, and avalanches accounted for as many as 12 % of all missions. The helicopter crews used static rope or rescue hoist in 141 operations.
We have described all helicopter supported SAR operations in our area by combining databases. The Tromsø HEMS service had taken over one half of the missions by 2010. Increased availability for SAR work is one potential explanation.
The number of SAR missions increased during 2000-2010, and the Tromsø HEMS experienced the greatest increase in workload.
搜索与救援（SAR）行动在挪威救护直升机任务中占很大比例，可能会限制该服务的医疗行动能力。我们使用SAR行动的通用定义比较了不同直升机资源的相对贡献，以调查过去几年中SAR工作量的变化情况。
我们在相关的SAR和直升机紧急医疗服务（HEMS）基地以及联合救援协调中心（北部）的任务数据库中搜索了2000 - 2010年特罗姆瑟HEMS基地潜在行动区域内直升机支持的SAR行动。我们将SAR行动定义为在距海岸10海里范围内的陆地或海上任务，包括初始搜索阶段、使用救援吊升设备或固定绳索的任务以及雪崩救援行动。
在639次不同的SAR行动中有769次请求，完成了600次任务。在研究期间数量有所增加，从2000年的46次增加到2010年的77次。特罗姆瑟HEMS执行的任务数量最多，且增长幅度最大，从2000年占行动的10%增至2010年的50%。简单地形和海上行动占主导，雪崩救援行动占所有任务的12%。直升机机组人员在141次行动中使用了固定绳索或救援吊升设备。
我们通过整合数据库描述了我们区域内所有直升机支持的SAR行动。到2010年，特罗姆瑟HEMS服务承担了一半以上的任务。SAR工作可用性增加是一个可能的解释。
2000 - 2010年期间SAR任务数量增加，特罗姆瑟HEMS的工作量增长最大。
