North American Rescue
MED-TAC International's Respiratory Support collection covers the "R" in the MARCH algorithm: chest seals, needle decompression devices, thoracostomy kits, and chest tube insertion systems used to manage open pneumothorax and tension pneumothorax in tactical and prehospital settings. Products from North American Rescue, Safeguard Medical, Boundtree Medical, Tactical Medical Solutions, and Prometheus Medical — sourced from the original manufacturer or authorized master distributor.
What Chest Injuries Require Immediate Respiratory Intervention in TCCC?
In the MARCH algorithm, the Respirations phase addresses two immediately life-threatening chest injuries. An open pneumothorax (sucking chest wound) occurs when a penetrating injury creates an opening in the chest wall — allowing air to enter the pleural space with each breath, collapsing the lung on the affected side. Treatment is immediate application of a vented chest seal to allow air to escape while preventing further entry. A tension pneumothorax occurs when air accumulates in the pleural space under pressure — compressing the lung, shifting the mediastinum, and ultimately compressing the opposite lung and the heart. It is rapidly fatal without intervention. Treatment is needle decompression: insertion of a large-bore needle into the second intercostal space, mid-clavicular line (or the fourth or fifth intercostal space, anterior axillary line for extended field care settings), to release the trapped air. Both injuries are common in penetrating chest trauma and blast injury — the leading mechanisms in combat and active shooter events. Proper management of chest injuries is detailed in the Joint Trauma System Clinical Practice Guidelines.
How Do Vented and Non-Vented Chest Seals Compare?
Current CoTCCC guidelines recommend vented (one-way valve) chest seals as the preferred choice for penetrating chest wounds in tactical environments. The table below compares the major chest seal options available from MED-TAC.

What Needle Decompression Devices Are Used for Tension Pneumothorax?
Needle chest decompression (NCD) requires a large-bore needle — typically 14 gauge, at least 3.25 inches in length — to reliably penetrate the chest wall across the range of patient body habitus encountered in clinical practice. Studies from the Joint Trauma System and military experience have identified needle length as a critical variable: shorter needles fail to penetrate the chest wall in a significant percentage of cases. MED-TAC carries dedicated NCD devices and kits for this purpose:
The ARS for Needle Decompression (North American Rescue) is a 14g, 3.25-inch needle with a one-way valve and finger-flange design for controlled insertion — widely issued with U.S. military and law enforcement medical kits. The MTI Chest Decompression Needle (MED-TAC International) provides a cost-effective, military-specification option in bulk quantities. The H&H Enhanced Pneumothorax Needle (H&H Medical / Safeguard) features an integrated flutter valve for post-decompression management. The TPAK Chest Decompression Needle (TacMed Solutions) is packaged for IFAK integration with a safety cap and marked insertion depth. The SPEAR (Simplified Pneumothorax Emergency Air Release) Device by North American Rescue provides a simplified deployment mechanism for use under stress. The Capnospot Pneumothorax Decompression Indicator (Pneumeric) assists in confirming accurate needle placement. For provider-level intervention, the collection also carries the North American Rescue Simple Thoracostomy Kit and Chest Tube Insertion Kit, as well as the TacMed Basic Chest Tube Kit.
When Should I Use a Chest Seal vs. Needle Decompression?
These two interventions address different phases of the same injury mechanism. A chest seal is applied immediately to a penetrating chest wound to prevent an open pneumothorax from developing — it should be placed as soon as the wound is identified, before any assessment of lung status. Needle decompression is a treatment for tension pneumothorax — a specific, life-threatening complication requiring clinical signs to diagnose: absent or diminished breath sounds on the affected side, increasing respiratory distress, tracheal deviation (late sign), hypotension, and distended neck veins. In TCCC under fire, a chest seal is placed prophylactically on all penetrating chest wounds. Needle decompression is performed when tension pneumothorax is suspected by clinical assessment. Both interventions can be required on the same patient. For comprehensive airway management supplies, see the Airway Management collection.

Frequently Asked Questions
What gauge needle is used for tension pneumothorax decompression?+
TCCC guidelines and the Joint Trauma System recommend a 14-gauge, minimum 3.25-inch needle for needle chest decompression. Multiple military and civilian studies have demonstrated that shorter needles (the standard 2-inch IV catheter) fail to reach the pleural space in 25–50% of patients due to chest wall thickness variation. The ARS device by North American Rescue (14g × 3.25 inches) was specifically designed to address this failure mode and is the most widely issued NCD device in U.S. military medical kits. The second insertion site (4th–5th ICS, anterior axillary line) is now recommended by JTS guidelines for extended field care settings as an alternative to the classic 2nd ICS mid-clavicular line site.
Why are vented chest seals preferred over non-vented (occlusive) seals?+
Current CoTCCC guidelines recommend vented chest seals because a non-vented (fully occlusive) seal can convert an open pneumothorax into a tension pneumothorax by trapping air inside the pleural space during exhalation. A vented seal allows air to escape through the valve during exhalation while preventing air entry during inhalation — managing the open wound without creating a closed-system pressure problem. Non-vented seals have a role when a vented seal is unavailable or in specific clinical scenarios directed by a provider; however, for standard tactical use, vented seals are the evidence-based preference.
Does a chest seal need to be applied to both an entry and exit wound?+
Yes. TCCC guidelines direct providers to assess for and seal both entry and exit wounds in penetrating chest trauma. A single-entry penetrating wound with no exit wound requires one seal; a through-and-through penetrating wound requires two seals — one on each opening. This is why chest seals are often sold in twin packs (e.g., HyFin Vent Twin Pack, HALO Vent Twin Pack). Providers should conduct a thorough chest assessment, including posterior chest inspection, before completing the respiratory phase of MARCH.
What is a simple thoracostomy and when is it used instead of needle decompression?+
A simple thoracostomy is a finger-sized incision made into the pleural space at the 4th–5th intercostal space, anterior axillary line, to rapidly decompress a tension pneumothorax — particularly in patients who are intubated (where needle decompression is less reliable due to positive pressure ventilation). In TCCC for combat medical personnel, simple thoracostomy is authorized as an alternative to needle decompression when the provider has the training and equipment. The North American Rescue Simple Thoracostomy Kit contains the necessary instruments for this procedure. It is a provider-level skill requiring formal training and is not appropriate for use by untrained personnel.
Can chest seals be applied over clothing or on hairy skin?+
Ideal application is on clean, dry skin — but tactical and trauma environments rarely offer ideal conditions. Most modern chest seals use hydrogel or pressure-sensitive adhesive designed to bond over moisture, blood, and body hair better than older occlusive dressings. The HyFin Vent and HALO Seal lines are specifically engineered for performance in contaminated wound environments. In practice, the provider should expose the wound, wipe away as much blood and debris as possible with the dressing packaging or a gloved hand, and apply the seal with firm pressure around the wound margins. Even imperfect seal application is better than no seal; providers should monitor and reposition if seal failure occurs.
What is the SENTINEL Chest Trauma Kit and what does it contain?+
The SENTINEL Chest Trauma Kit by Combat Medical Systems is a self-contained, packaged kit designed for complete management of penetrating chest trauma. It includes chest seals (vented), a needle decompression device, and supporting supplies in a single waterproof pouch — eliminating the need to carry and stage multiple individual components. It is designed for IFAK-level integration and is particularly useful for personnel who want a complete, ready-to-deploy chest trauma solution in a compact package rather than building from individual components.
