From the US Army - Tourniquet Recommendations
(July/August 2004)

Recent testing of many different types of potential battlefield tourniquets by the US Army’s Institute of Surgical Research (USAISR) was fully independent from the manufacturers of all of the tourniquets tested. In USAISR testing, Delfi EMT pneumatic tourniquets were successfully applied and successfully stopped blood flow in all trials on all volunteers. There were no failures of any kind using the Delfi EMT pneumatic tourniquet and pain scores were dramatically lower than all other devices tested.

"[Based on the US Army’s Institute of Surgical Research test results] ... it is recommended that the [Delfi] EMT pneumatic tourniquet be considered for issue to combat medics. Further, it is recommended that the [Delfi] EMT be issued for all medical evacuation vehicles and echelon I-III medical facilities."

"The [Delfi] EMT pneumatic tourniquet was wider and thus significantly less painful than any device tested and is much less likely to induce nerve damage".
