STAT Tourniquet_ 21 of 24 applications FAIL

“ “Crisis Medicine“: We tested 24 self-applied high on the thigh STAT tourniquets on volunteers, verifying occlusion of arterial vascular flow by doppler ultrasound in the posterior tibial artery. We had 3 successful applications, 2 devices had mechanical failure (the locking mechanism slipped and would not allow continued tightening). Of the tested devices, 21 failed to achieve vascular occlusion.
