Pressure Responses of Tourniquet Practice Models to Calibrated Force Applications.

Background: Tourniquet training sometimes involves models, and a certification process is expected to use something other than human limbs; therefore, investigating model- and limb-pressure responses to force application is important.

Methods: Pressure response to force was collected for a 3.8cm-wide nonelastic strap and a 10.

Limb Position Change Affects Tourniquet Pressure.

Background: Limb position changes are likely during transport from injury location to definitive care. This study investigated passive limb position change effects on tourniquet pressure and occlusion.

Methods: Triplicate buddy-applied OMNA® Marine Tourniquet applications to Doppler-based occlusion were done to sitting and laying supine mid-thigh (n=5) and sitting mid-arm (n=3).

OMNA Marine Tourniquet Self-Application.

Background: The OMNA Marine Tourniquet is a 5.1cm-wide, simple redirect buckle, hoop-and-loop secured, ratcheting tourniquet designed for storage and use in marine environments. This study evaluated self-application effectiveness and pressures.

Clothing Effects on Limb Tourniquet Application.

Background: Sometimes tourniquets are applied over clothing. This study explored clothing effects on pressures and application process.

Methods: Generation 7 Combat Application Tourniquets (C-A-T7), Generation 3 SOF® Tactical Tourniquets-Wide (SOFTTW), Tactical Ratcheting Medical Tourniquets (Tac RMT), and Stretch Wrap And Tuck Tourniquets (SWATT) were used with different clothing conditions (Bare, Scrubs, Uniform, Tights) mid-thigh and on models (ballistic gel and yoga mats).

Characterizing a System for Measuring Limb Tourniquet Pressures.

Background: Pressure is an important variable in emergency use limb tourniquet science. This study characterizes one system for measuring tourniquet-applied pressure.

Methods: A neonatal blood pressure cuff bladder was inflated to target pressures over atmospheric.
