To determine whether an accessory to the Bair Hugger warming unit (BHWU), a piece of equipment intrinsic to the forward surgical team, could be designed and used to warm and to maintain large volumes of intravenous fluids at an optimal infusion temperature in an austere environment.
The X-1 is a simple, collapsible, 5-gallon nylon cooler with handles, modified with a port for the BHWU hose and a one-way flutter valve vent.
The warming of intravenous fluids to the optimal infusion temperature was accomplished with the BHWU and X-1. The warming time was influenced by the ambient temperature, the starting temperature of the fluids, and the number of bags being warmed. The warmed fluid could be stored and maintained in the X-1. The heat retention of the fluids was influenced by the ambient temperature, the number of bags warmed, and the insulating properties of the X-1.
The BHWU can be used with the compact X-1 to warm and to store large volumes of intravenous fluids at the optimal infusion temperature in the field environment and was successfully used by a forward surgical team in Afghanistan, during Operation Enduring Freedom, for the treatment of combat-wounded soldiers.
确定前送手术团队所使用的一种设备——贝尔胡格保暖装置（BHWU）的附件，是否能够在简易环境中被设计并用于将大量静脉输液加热并维持在最佳输注温度。
X-1是一个简单的、可折叠的5加仑尼龙冷却器，带有把手，经过改造，设有一个用于BHWU软管的端口和一个单向摆动阀通风口。
使用BHWU和X-1可将静脉输液加热至最佳输注温度。加热时间受环境温度、液体起始温度以及被加热袋子数量的影响。加热后的液体可储存在X-1中并保持温热。液体的保温效果受环境温度、被加热袋子数量以及X-1的隔热性能影响。
BHWU可与紧凑的X-1配合使用，在野外环境中将大量静脉输液加热并储存于最佳输注温度，在持久自由行动期间，阿富汗的一支前送手术团队成功地使用该装置治疗战斗受伤士兵。
