COOLING SOP & SCIENCE

TO Instruction_B.png

A lid-mounted cooling guide for heat illness response.

Cold Strike™ keeps the response steps visible when the scene is hot, loud, and time-sensitive. 

The lid-mounted guide gives teams two field-ready cooling pathways: ice sheets for heat exhaustion and emergency immersion for suspected heat stroke.

TWO PATHWAYS. ONE KIT.

Cold Strike™ is designed to help teams move quickly from recognition to cooling while following their organization's heat casulty protocols.

HEAT EXHAUSTION
Apply Ice Sheets.

Move to shade. Remove outer clothing and gear. Apply ice sheets and re-wet them as needed while monitoring for worsening symptoms.

SUSPECTED HEAT STROKE
Call 911. Start Emergency Immersion.

If the casualty shows slurred speech, abnormal thinking or behavior, seizures, or loss of consciousness, activate EMS and begin cooling immediately using the included immersion bag, ice, water, and sheets.

Follow your medical director, EMS agency, athletic training staff, occupational health team, or organization's heat casulty protocols.

RESEARCH SUPPORTING RAPID FIELD COOLING

Cold Strike™ is built around a simple operational principle: heat casualty outcomes improve when cooling can begin quickly, using equipment already staged at the point of need.

The research below supports the cooling methods and response logic behind Cold Strike™: rapid cooling, field-expedient immersion, and ice-sheet or ice-water towel cooling when tradtional immersion is not immediately practical. These sources are not product-specific clinical trials of the Cold Strike™ kit.

RECENT STUDIES SUPPORTING OUR APPROACH

Prehospital  rapid-cooling bag protocol

2026 Prehospital Emergency Care study of Phoenix Fire Department protocol found rapid temperature reduction and improved neurologic status when using a prehospital CWI protocol.

Rotating ice-water towels at running events

A 2025 study evaluated rotating ice-water towels for exertional heat stroke at running events and found them practical when immersion is constained.

Body bag immersion when a tub is not available

2023 case report describing severe heat stroke resuscitation using a body bag filled with ice and water when a traditional bath was not available.

Ice-sheet cooling after exertional hyperthermia

A 2022 study found ince-sheet cooling increased cooling rates after exertional hyperthermia and may support field cooling when immersion is unavailable.

Cold-water immersion in disposable body bag

2020 case report of successful use of a disposable body bag for cold-water immersion in non-exertional heat stroke. Rapid cooling is imperative to minimize mortality and morbidity.

Prehospital ice-sheet cooling in EHS casualties

A prehospital EHS study supports ice sheets as a field cooling option when practical limitations prevent immediate cold-water immersion.

IMPORTANT INFORMATION

Cold Strike™ is a cooling support system. It does not replace medical training, EMS activation, medical direction, or organizational heat illness protocols.

 

Teams should follow their medical director, EMS agency, athletic training staff, occupational heath team, or organizational heat illness protocols.
