Reinforced Heat Reflective Shell

Key Specifications

Product Overview

The North American Rescue® Reinforced Heat Reflective Shell (HRS™) addresses one of the most critical — and frequently overlooked — threats to combat and tactical casualties: hypothermia. Preventable hypothermia is a significant contributing factor in combat trauma deaths; the HRS™ was engineered specifically to prevent heat loss during prolonged casualty care, transport, and evacuation. The 4-ply composite construction incorporates a protected, non-conductive reflective layer that traps radiant body heat while the outer plies provide physical protection and durability in austere environments.

What sets the Reinforced HRS™ apart from standard emergency blankets is its structural integrity and usability under pressure. The 1.5-inch continuous Velcro® closures run the full length of the shell, allowing the treating medic to open the wrap at any point for assessment, intervention, or IV access without removing the patient from thermal protection. The built-in hood further reduces heat loss from the head — one of the most significant zones of radiant heat loss — while the integrated fluid absorption pad manages wound drainage without compromising insulation.

The reinforced design is weight-tested to support 250+ lb, meaning the HRS™ can serve as a patient drag or litter assist without tearing, a critical capability during casualty movement under fire. The tapered shape — wider at the shoulders and narrowing toward the feet — maximizes isothermal efficiency by minimizing dead air space. NAR's HRS™ is widely used across military, law enforcement tactical medic, and civilian EMS contexts as a standard-of-care thermal management tool at the point of injury.

How to Use

1. Complete initial hemorrhage control and airway management before wrapping.
2. Open the HRS™ fully and position the built-in hood beneath the patient's head.
3. Wrap the shell around the casualty, sealing the Velcro® closures from feet upward.
4. Use the tapered end to seal the foot section tightly to eliminate heat loss.
5. For reassessment or intervention, open the Velcro® closures locally — the shell remains in place over the rest of the body.
6. The fluid absorption pad at the base manages wound drainage automatically.

Hypothermia in Trauma: Why Thermal Management Matters

The "lethal triad" of trauma — coagulopathy, acidosis, and hypothermia — is well-established in emergency medicine literature. Even mild hypothermia (core temperature below 36°C / 96.8°F) significantly impairs platelet function and clotting factor activity, worsening hemorrhagic shock. In field settings, casualties rapidly lose core temperature due to exposed wounds, IV fluid administration, cool ambient temperatures, and lying on cold surfaces. Thermal management tools like the HRS™ are a critical third pillar of hemorrhage control, working in parallel with tourniquets and hemostatic dressings to prevent coagulopathy from compounding an already critical wound profile.
