Independent Peer-Reviewed Research
Results: Thirty-one subjects had arm circumferences ≥30cm. All 540 applications were effective.
Conclusions: The OMNA Marine Tourniquet can be self-applied effectively, including one-handed applications.

Limb Position Change Affects Tourniquet Pressure
Results: Sitting thigh occlusion pressures leg bent were higher than straight.
Conclusions: Passive limb position changes can cause significant changes in tourniquet pressure. Therefore, tourniquet adequacy should be reassessed after any limb position change.
Results: The mean percentage loss of tensile strength for the CAT tourniquet webbing was −19% at 3-months and −87% at 6-months. In contrast, the mean percentage loss of tensile strength for the OMT tourniquet webbing was −2% at 3-months and −16% at 6-months.
Conclusions: The OMNA Marine Tourniquet Gen 2 webbing demonstrated significantly more photodegradation resistance and maintenance of tensile strength compared to the CAT Tourniquet Gen 7 webbing.
Results: The ratcheting marine-designed OMNA ranked the highest for application easiness on both the upper and lower extremities.
Conclusions: Civilian extremity tourniquet self-application on both upper and lower extremities can be accomplished in cold weather conditions despite using cold-weather gloves and technical clothing after receiving brief training. The ratcheting marine-designed OMNA ranked the highest for application ease.
Results: Regarding the upper extremity, OMNA achieved the highest score of 8.5 out of 10. Overall, OMNA was the best performer.
Conclusions: Out of the 5 TQs tested, 60% of subjects preferred OMNA. The study concluded that self-application of commercial TQs are feasible over cold-water anti-exposure suits in the Antarctic climate.
Results: For occluded, tightening system secure applications, from "touch tightening system" to "Done" was fastest with self-securing tightening systems tightening from a tight strap.
Conclusions: Optimal design features for fast, occlusive, secure tourniquet applications are self-securing strap/ redirect systems with an easily identified and easily used clip and self-securing tightening systems.
Results: With the T-OMNA, 46% of the lifeguards successfully stopped the MH compared to 21% with the T-CAT (P = .015). The approach swim time was 135 seconds with the T-OMNA and 131 seconds with the T-CAT (P = .42). The total time (swim time plus tourniquet placement) was 174 seconds with the T-OMNA and 177 seconds with the T-CAT (P = .55). The adjustment time (from securing the Velcro to completing the manipulation of the windlass or ratchet) for the T-OMNA was faster than with the T-CAT (six seconds versus 19 seconds; P < .001; effect size [ES] = 0.83). The perceived fatigue was high, with a score of seven out of ten in both tests (P = .46).
Conclusions: Lifeguards in this study demonstrated the ability to use both tourniquets during aquatic rescues under conditions of fatigue. The tourniquet with the ratcheting-fixation system controlled hemorrhage in less time than the windlass rod-based tourniquet, although achieving complete bleeding control had a low success rate.
OMNA Marine Tourniquet Application
Instructions For Use
Current OMT Estimated CoTCCC Recommendation Score = 40.7
Estimated score is based on published research, real world use reports, and CoTCCC Tourniquet criteria. The minimum score for recommendation is 40 out of 50 + a majority vote by the CoTCCC. OMNA is currently working to meet all efficacy and logistics criteria.
