PRODUCT INFORMATION

North American Rescue — Chest Seal

HyFin® Vent Chest Seal — Individual Pack

The full-size 6″ × 6″ vented seal, sold one at a time for custom IFAK builds, restocking, and training programs.

Single seal6″ × 6″3-channel vent~1.31 oz

Twin packs are right for operational carry, but not every need is a matched pair. Custom kit builds, single-seal restocks, and training stations call for one seal at a time — without breaking open a twin pack to do it.

Why buy two when the kit calls for one?

The Individual Pack is the full-size HyFin® Vent — the same 6″ × 6″ seal with the patented 3-channel pressure-relief venting as the twin pack, packaged singly. Ideal for operators who select each component, agencies restocking a single used seal, and instructors demonstrating application one wound at a time.

Built For

Custom IFAK Builds

Select exactly the seals your protocol calls for — pair a single Vent with a single Occlusive to mirror the USMC Combo from individually sourced parts.

3-Channel Fail-Safe Vent

Air escapes the pleural space on exhalation and is blocked on inhalation. Two of three channels can occlude before venting is lost.

Full 6″ × 6″ Coverage

Greater adhesive contact than the Compact (4.75″) version — optimal for large or irregular wound margins.

Training-Friendly

One seal per package suits familiarization and skills stations without opening operational twin packs.

Vented Seal per CoTCCC 2024 TCCC Guidelines

The 2024 TCCC Guidelines direct vented chest seals as the first-line treatment for open and sucking chest wounds. The HyFin® Vent's 3-channel design (U.S. Patent 7,504,549) maintains pressure relief even when partially occluded. After placement, monitor for tension pneumothorax and burp the seal via the red tab if tension signs develop.

Who Buys Singles

When to Deploy Hyfin Vent Chest Seal- Individual Pack

Penetrating chest trauma — immediate application: Apply the HyFin® Vent immediately after identifying a penetrating chest wound to prevent air accumulation and tension pneumothorax development.
CoTCCC MARCH protocol — Respiration step: The HyFin® Vent is the standard field treatment for the R in MARCH — Respiration/chest trauma management.
Simultaneous entry and exit wounds: Individual packs allow separate seals for entry and exit wounds when a Twin Pack is not available or only one wound requires treatment.
Kit restocking and cache builds: Individual packs enable cost-effective multi-seal caching without committing to Twin Pack quantities for each stockage location.
Training drills: Individual packs are used for training applications where the training scenario does not require a full Twin Pack deployment.
Kit customization: Operators building custom IFAKs select individual packs for full control over kit composition and seal count.

For most penetrating chest trauma scenarios, carry a HyFin® Vent Twin Pack — it provides both seals needed for entry and exit wounds in a single package. The individual pack is for restocking, secondary kit builds, and kit customization where Twin Pack format is not preferred.

How Hyfin Vent Chest Seal- Individual Pack Compares

HyFin® Vent Individual Pack vs Twin Pack: The Twin Pack contains two HyFin® Vent seals in a single package — the standard CoTCCC IFAK configuration that addresses both entry and exit wounds simultaneously. The individual pack contains one seal. For new kit builds, the Twin Pack is preferred; individual packs suit restocking and secondary kit configurations.

HyFin® Vent vs flat-style chest seals: The HyFin® Vent's vented design allows air to escape from the pleural space on exhalation while preventing ambient air entry on inhalation — addressing the pathophysiology of tension pneumothorax without requiring a provider to perform needle decompression in every chest wound case. Flat (non-vented) seals require monitoring for tension pneumothorax and may need to be burped or replaced with a vented seal.

CoTCCC recommendation: The HyFin® Vent Chest Seal is CoTCCC-recommended for penetrating chest trauma. It is the standard chest seal referenced in TCCC and TECC curricula and included in military and law enforcement IFAK configurations worldwide.

Frequently Asked Questions

Q: Is the HyFin Vent Chest Seal CoTCCC-recommended?

A: Yes. The HyFin® Vent Chest Seal is CoTCCC-recommended for penetrating chest trauma as a vented chest seal. It is the standard chest seal referenced in TCCC and TECC curricula, included in military IFAK configurations, and listed under federal supply NSN for government procurement.

Q: What is the difference between the individual pack and the Twin Pack?

A: The individual pack contains one HyFin® Vent Chest Seal; the Twin Pack contains two seals. For most penetrating chest trauma scenarios, two seals are needed — one for the entry wound and one for the exit wound. The Twin Pack is the standard CoTCCC IFAK configuration. Individual packs suit restocking, secondary kit builds, and custom kit configurations where only one additional seal is needed.

Q: How does the vented design of the HyFin® prevent tension pneumothorax?

A: The HyFin® Vent's flutter-valve mechanism allows air to escape from the pleural space on exhalation, preventing the progressive air accumulation that leads to tension pneumothorax. On inhalation, the valve closes to prevent ambient air entry. This passive pressure-relief mechanism reduces the incidence of tension pneumothorax development under sealed chest wounds.

Q: Can the HyFin® Vent seal be applied through a plate carrier or clothing?

A: The HyFin® Vent is designed for direct skin application for optimal seal. If applied through clothing, the adhesive contact and seal integrity are compromised. Standard protocol is to remove or cut away clothing to expose the wound site for direct skin application. Some training scenarios practice clothing-through application as a degraded technique when direct access is not possible.

Q: What NSN applies to the HyFin® Vent Chest Seal Individual Pack?

A: HyFin® Vent Chest Seals are listed in the DLA medical supply catalog. The specific NSN for the individual pack should be confirmed with North American Rescue or DLA cataloging. The Twin Pack also carries a separate NSN. Contact MED-TAC International for procurement support and current NSN data.

CLINICAL RATIONALE

Chest Seals in Thoracic Trauma

Chest seals are critical life-saving tools for treating open chest wounds (sucking chest wounds) that disrupt the negative pressure needed for normal breathing.
When air enters the pleural space through a penetrating injury, it prevents the lung from fully expanding and may lead to a tension pneumothorax — a life-threatening condition if not addressed promptly.
Properly applied chest seals restore intrathoracic pressure balance and allow the injured lung to re-expand, buying vital time until definitive care or decompression is available.

1. Vented Chest Seals

Clinical Rationale (Vented):

Vented chest seals feature one-way valves or channels that allow trapped air and fluids to escape from the chest cavity while preventing further air entry.
This controlled venting mechanism reduces the risk of developing a tension pneumothorax and is recommended by the Committee on Tactical Combat Casualty Care (CoTCCC) for most open thoracic injuries when the vent remains unobstructed.
In tactical and emergency medical settings, vented seals maintain proper intrathoracic pressure dynamics and help stabilize respiration during evacuation.

Allows air and blood to escape while blocking additional air entry
Recommended by CoTCCC for most penetrating chest wounds
Prevents progression to tension pneumothorax
Effective during movement and transport phases

2. Non-Vented Chest Seals

Clinical Rationale (Non-Vented):

Non-vented chest seals provide a fully occlusive barrier that prevents any external air from entering the pleural cavity.
These are preferred when environmental factors — such as dust, debris, heavy clothing, or complex wound locations — could obstruct a vent or prevent it from functioning properly.
Non-vented models are especially effective when there are multiple wounds or when both sides of the chest are compromised.

Creates an airtight seal to stop further air intrusion
Ideal for contaminated or complex wound environments
Preferred for posterior or multiple thoracic injuries
Simple and reliable under stress conditions

3. Twin Pack / Dual Application

Clinical Rationale (Twin Pack):

Twin chest seal packs are designed for simultaneous coverage of entry and exit wounds or multiple penetrating thoracic injuries.
Applying seals to both anterior and posterior wounds prevents air intrusion from either side and ensures consistent intrathoracic pressure stabilization.
This configuration allows medics and responders to treat through-and-through injuries quickly and efficiently without improvisation.

Enables rapid treatment of entry and exit wounds
Maintains consistent chest pressure across both sides
Optimized for tactical and prehospital trauma management
Reduces need for multiple packages or improvised seals

4. Training Chest Seals

Clinical Rationale (Training):

Training chest seals replicate the adhesive strength and venting design of operational models using non-sterile materials.
They are intended for classroom, simulation, and scenario-based instruction, allowing responders to practice correct placement, adhesion, and vent inspection without wasting live medical gear.
Consistent repetition with realistic trainers develops muscle memory and speed during actual trauma incidents.

Simulates vented or occlusive seal behavior for realistic training
Promotes correct placement and adhesion technique
Preserves sterile operational supplies
Ideal for EMT, tactical, and civilian responder courses

Clinical Summary

Chest seals play a pivotal role in preventing death from tension pneumothorax, one of the leading causes of preventable trauma mortality.
Both vented and non-vented designs serve distinct operational needs, while twin and training packs ensure preparedness across all care phases — from education to battlefield or civilian emergencies.

Vented: Allows controlled egress of trapped air; standard CoTCCC-recommended choice.
Non-Vented: Fully occlusive; best for debris-rich or posterior wound sites.
Twin Pack: Provides coverage for through-and-through injuries.
Training: Non-sterile practice tool for skill retention and readiness.

By re-establishing chest wall integrity and controlling air movement, chest seals restore lung expansion and stabilize respiratory mechanics until advanced medical care is available.
