SEAL PRO Stopped an Arterial Bleed at an Indoor Training Event

I’ve been a medic for 35+ years: NYC EMS, NYFD, City of Miami, Miami-Dade County, and federal emergency operations. I’ve used nearly every clotting agent on the market. I’m also a Stop the Bleed instructor.

About four months ago, I was at an indoor training event. Someone was showing off a brand-new custom knife, a velociraptor claw design, extremely sharp. Within minutes it had sliced through a bystander’s hand. The knife passed through the thumb, along the inside edge of the pointer finger, and deep into the tissue between the two.

We attempted to place a tourniquet high and tight, but the blood flow was too fast to get it seated properly on the first try. A second tourniquet was added. Something else had to be done immediately to slow the flow.

I had a medical kit on my range bag with a SEAL PRO attached to the outside. It reminded me the can was inside. I grabbed it along with pressure bandages.

I had never used it before. For a moment I hesitated. I didn’t know exactly how it would work, how much to use, or whether it would hold. Thirty-five years of experience and those thoughts still ran through my head. I had a name-brand backup ready if needed.

The SEAL PRO, used with direct pressure, materially slowed what appeared to be a combination of a deep vein bleed and an arterial nick, down to a manageable trickle within seconds. The tourniquet became a precautionary step rather than a necessity.

The patient remained conscious and alert the entire time. He arrived at the trauma center in Miami awake and stable.

I have never seen a clotting agent work that fast, that effectively, in a real situation. This product belongs in every trauma kit, every ambulance, every range bag, and every first responder kit in the field.

If I hadn’t known it was there, things could have gone differently.

A Note from SEAL

This is exactly the scenario SEAL PRO was built for. A wound that deep, with a likely arterial component, requires immediate hemostatic intervention before a tourniquet can be properly seated. Standard pressure alone isn’t enough when the flow is that fast.

SEAL PRO’s chitosan aerosol forms a physical barrier on contact, without requiring packing, without requiring training to apply correctly, and without losing effectiveness under active bleeding. It buys the seconds you need to get everything else in place.

When a 35-year medic and Stop the Bleed instructor reaches for a product he’s never used before, in a real emergency, under pressure, and calls it the best clotting agent he’s ever seen, that’s not a review. That’s field validation.
