JSOM OMNA Marine Tourniquet - Stop The Bleed TCCC TECC

ABSTRACT

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 environ- ments. This study evaluated self-application effectiveness and pressures. Methods: Triplicate secured, occlusion, and comple- tion pressures were measured during 60 subjects pulling down or up thigh applications and nondominant, single-handed arm applications. Arm pressure measurements required circumfer- ences 30cm. Results: Thirty-one subjects had arm circumfer- ences 30cm. All 540 applications were effective; 376 of 453 applications had known secured pressures >150mmHg (89 of 93 arm). Thigh down versus up pulling directions were not different (secured, occlusion, and completion pressures and ladder tooth advances). Occlusion pressures were 348mmHg (275–521mmHg) for combined thighs and 285mmHg (211– 372mmHg) for arms. Completion pressures were 414mmHg (320–588mmHg) for combined thighs and 344mmHg (261– 404mmHg) for arms. Correlations between secured pressures and occlusion ladder tooth advances (clicks) were r2 = 0.44 for combined thighs and 0.68 for arms. Correlations between occlusion pressures and occlusion clicks were poor (r2 = 0.24, P < .0001 for combined thighs and r2 = 0.027, P = .38 for arms). Conclusions: The OMNA Marine Tourniquet can be self-applied effectively, including one-handed applications. Occlusion and completion pressures are similar to reported 3.8cm-wide Ratcheting Medical Tourniquet pressures.
