Product Overview

Low Titer Type O Whole Blood (LTOWB) is the resuscitative fluid of choice for hemorrhagic shock per CoTCCC guidelines — providing red blood cells, platelets, and clotting factors in balanced physiologic proportion without the logistical requirements of cold-chain stored component therapy. The NAR LTOWB Administration Set-V is the recipient half of NAR's walking blood bank solution, designed to pair with the Collection Set-V (83-0031) for a complete field transfusion capability.

The 'V' in the product designation indicates the Valkyrie program lineage — the USMC MARSOC walking blood bank system that validated prescreened LTOWB as a systematic far-forward resuscitation capability. The Ranger O Low-Titer Blood (ROLO) program in the 75th Ranger Regiment pioneered a similar approach for Army Special Operations. These programs validated that prescreened type O low-titer donors within an operational unit can be systematically activated to provide whole blood at or near the point of injury — an approach that has demonstrated survival benefit in both military and civilian trauma settings.

The Administration Set-V simplifies the field blood administration process: dual 16g IV catheters enable redundant large-bore access in even compromised venous anatomy, the Y-type blood set with filter provides simultaneous saline flush and blood administration ports, Chloraprep swabsticks (superior to standard alcohol prep for central line care) reduce infection risk, and the Bear Claw nitrile gloves provide tactile dexterity combined with puncture resistance. The included TCCC card and ASBP 572-EWB card satisfy documentation requirements for blood chain-of-custody at higher echelons.

The beaded cord (11 in.) and 550 cord (10 in.) are field-expedient suspension devices for hanging the 450 mL blood bag in the absence of IV poles or JACK hooks — a detail that reflects NAR's depth of experience designing kits for genuine austere environments.

Walking Blood Bank Operations: LTOWB Context

LTOWB donors are pre-screened personnel who are blood type O with low titers of anti-A and anti-B antibodies (1:200 or less). This low-titer status reduces the risk of hemolytic transfusion reactions in non-type-O recipients compared to standard type O whole blood. Pre-screening is conducted during unit medical readiness events. At point of casualty, the LTOWB Collection Set-V (83-0031) is used to draw from a pre-identified donor, and the Administration Set-V (this product) is used to transfuse the collected unit to the recipient.
