North American Rescue HyFin® Vent Chest Seal

When you’re dealing with a chest wound, time and air are both working against you.

The HyFin® Vent Chest Seal is designed to treat penetrating chest injuries by sealing the wound while still allowing trapped air to escape—helping prevent a life-threatening tension pneumothorax.

The 3-channel vent system acts as a one-way valve, allowing air to escape from the chest cavity while preventing outside air from being pulled back in. That’s what makes the difference between stabilizing the injury… and making it worse.

Built with an advanced adhesive, this seal is made to stick in real-world conditions—sweat, blood, hair—it doesn’t matter. When you apply it, it stays put.

Compact, simple, and fast to deploy, this is a critical piece of gear for any real trauma kit.

Why It Matters:

Stopping bleeding is only part of the problem.

If air is getting into the chest where it shouldn’t be, this is what keeps it from turning fatal.
