PRODUCT INFORMATION

Sentinel™ by Safeguard Medical · Vented Chest Seal

Sentinel™ Chest Seal — Dual Vent

A transparent vented chest seal built to move blood and air out by separate paths: blood collects in an internal gap and drains through the lower vent while air leaves through the upper vent, so the adhesive stays down. A 360° ring of Sentinel 10x™ acrylate adhesive and a two-part peel go on in two steps. Each pouch holds one seal and a gauze wipe for the skin.

Vented — dual vent360° acrylate adhesiveGauze wipe in the pouchTransparentNSN 6510-01-600-4628

A vented seal is only vented while blood is not blocking the vent. The Sentinel gives the blood its own exit — then the skin prep is on you.

The short answer

What it is

A single-use vented chest seal with two vents and a 360° acrylate adhesive ring, packed with a gauze wipe.

Use it for

An open or sucking chest wound — front, back or side. The TCCC Guidelines call for a vented chest seal on every one.¹

How it's used

Clean and dry the skin with the enclosed wipe, peel liner 1 and center the seal, then peel liner 2 as the casualty breathes out and press it down all around. Seal the exit wound, then watch the breathing.⁴

Who carries it

Military medics and service members, law enforcement, EMS and tactical EMS, and trained civilians building an IFAK — two seals per kit.

12 things to know about the Sentinel Chest Seal

How the two vents work, how to apply it, and what the swine studies found — good and bad.

01

Two vents, two jobs

The Sentinel's dressing has an internal gap where blood can collect. Blood drains through the lower vent and air leaves through the upper vent, which lets the adhesive stay fully down on the casualty.⁵ Safeguard Medical describes a multi-layer design whose channels minimize vent occlusion while releasing blood and air at the same time.³
02

Acrylate, not hydrogel

The seal is held by a 360° ring of Sentinel 10x™ adhesive — an acrylate that is not water-based.³ The Russell, Bolin and SAM seals compared below use hydrogels instead.
03

A two-part peel

Liner 1 comes off first so you can center the seal and tack it down; liner 2 comes off as the casualty breathes out, and then the whole seal is pressed firmly onto the chest.⁴ Safeguard Medical designed the two-part peel for accurate placement.³
04

Transparent

You can see the wound through the applied seal, so you can watch for blood pooling and check placement without lifting it.³
05

6.5 × 6.5 inches

The Defense Logistics Agency record lists the dressing at 6.5 × 6.5 × 0.24 in.⁵ The packaged seal measures 19.7 × 14 × 1.3 cm and weighs 0.7 oz.³
06

A gauze wipe in every pouch

Each pouch holds one vented chest dressing and one gauze wipe; step 1 of the instructions is to clean and dry the area around the wound with it.^4,6
07

Perfect score in a bleeding chest-wound model

U.S. Army researchers sealed bleeding chest wounds in 26 swine and challenged each seal with more blood and air. The Sentinel and the Russell succeeded in 6 of 6 animals; the HyFin in 4 of 6, the SAM in 1 of 4 and the Bolin in 0 of 4.⁸ A 2021 systematic review reached its consensus recommendation for the HyFin Vent and the Russell.¹⁵
08

No tension pneumothorax in a swine air-leak model

In 24 swine, the HyFin, SAM and Sentinel (8 each) all evacuated air and blood from the chest, and hemodynamic compromise did not develop with a seal in place.⁹ Safeguard Medical cites this study for the Sentinel's venting.³
09

The adhesion question

In a Navy study of eight vented seals on soiled swine skin, five went on to full testing — Bolin, Russell, FastBreathe, HyFin and SAM.¹⁰ A 2021 review of that study reports the Sentinel was one of three seals dropped in pretesting for poor adhesion.¹¹ Wipe and dry the skin, then press the whole adhesive ring down.
10

Store it between 15 and 27 °C

The pouch label gives a storage range of 15–27 °C (59–80 °F).⁴ Rotate seals that live in vehicles and outdoor kits.
11

Issued under NSN 6510-01-600-4628

The NSN is printed on every pouch and recorded by the Defense Logistics Agency under part number 20-001.^4,5 Item 20-001 is made in the USA by Safeguard US Operating, LLC.^3,4
12

Not evidence-based standard — and neither is any chest seal

The Evidence-Based Standard Devices & Adjuncts list has no chest-seal entries.² The TCCC Guidelines call for a vented chest seal without naming a brand.¹ Absence from the list does not by itself mean a product was tested and failed. The Sentinel is listed with the FDA as a Class I, 510(k)-exempt occlusive wound dressing.⁷

How to apply the Sentinel Chest Seal

The steps on the pouch, inside the TCCC approach to an open chest wound.

1

Find every hole. Expose the chest and check the back, the sides and the armpits — the back is the wound people miss. Never pack gauze into a chest wound.
2

Cover it now. Put a gloved hand over the hole — or have the casualty use their own — while you tear the pouch open.
3

Clean and dry the skin. Use the enclosed gauze wipe to clear blood, sweat and debris from around the wound.⁴
4

Peel liner 1 and center. Center the dressing over the wound and press the exposed adhesive onto the skin.⁴
5

Peel liner 2 on the out-breath. As the casualty breathes out, remove liner 2 and press the dressing firmly onto the chest. Make sure the seal is complete all the way around.⁴
6

Seal the second hole. An exit wound gets its own seal. Carry two.
7

Position and reassess. Unconscious and breathing: recovery position. Conscious: a position of comfort, often sitting up. Reassess the seal and the breathing, again and again.⁴
8

If breathing gets worse, burp or remove it. Increasing distress, falling oxygen saturation or shock can mean a tension pneumothorax: lift the edge of the seal or remove it. Trained providers decompress the chest as the TCCC Guidelines direct.¹

Train before you need it. The Sentinel is single use and made for trained medical providers.⁴ Practice the two-part peel on a chest seal application trainer, gloved, and keep the live seals sealed in the kit.

Where it fits

Use it for

Open or sucking chest wounds — front, back or side — from gunshot, stab or fragment injuries¹
The exit wound as well as the entry wound: one seal per hole
Bleeding chest wounds, where blood needs a path out that does not lift the adhesive⁵
Securing a water-impermeable cover over eviscerated abdominal organs that cannot be replaced; the TCCC Guidelines name a chest seal as one adhesive option¹

Not for

Packing — never pack anything into the chest or abdomen
Skin you have not wiped and dried — use the wipe in the pouch⁴
Routine use on a patient receiving positive-pressure ventilation — the NAEMSP position is that chest seals may be harmful there¹⁴
Reuse — single use only⁴
Practice — train on a chest seal trainer

Questions buyers ask

▾Is the Sentinel Chest Seal evidence-based standard?

No. The Evidence-Based Standard Devices & Adjuncts list (15 December 2021) has no chest-seal entries, so no chest seal from any maker is evidence-based standard by name.² Absence from the list does not by itself mean a product was tested and failed. The TCCC Guidelines call for a vented chest seal on every open or sucking chest wound — and the Sentinel is vented.¹

▾Why two vents?

So blood and air do not fight for the same exit. Blood collects in an internal gap and drains through the lower vent, air leaves through the upper vent, and the adhesive stays down.⁵ In a bleeding chest-wound model, seals that let blood out this way worked; seals whose valves filled with blood or clot did not.⁸

▾Vented or non-vented — does it matter?

The TCCC Guidelines call for a vented chest seal first and a non-vented seal when no vented one is available; either way the casualty is watched for a developing tension pneumothorax.^1,13 In swine with an ongoing air leak, the vented seal prevented tension and the unvented seal did not.¹² A vent lowers the risk; it does not remove it.

▾What if breathing gets worse after the seal is on?

Treat it as a possible tension pneumothorax: burp the seal by lifting an edge, or remove it. Trained providers decompress the chest with a needle as the TCCC Guidelines direct.¹ Keep reassessing.

▾Will it stick to a sweaty or bloody chest?

Only if you prepare the skin. The acrylate ring holds on clean, dry skin; one swine-skin screen dropped the Sentinel in pretesting for poor adhesion.¹¹ Use the enclosed wipe, dry the area, and press the whole adhesive ring down after liner 2 comes off.⁴

▾What's in the pouch?

One vented chest dressing and one gauze wipe, sold individually.^4,6 The NSN 6510-01-600-4628 is printed on the pouch.^4,5 Carry two seals per kit — an exit wound needs its own.

▾I'm a bystander without a chest seal. What do I do?

Cover the hole with a gloved hand, or have the casualty press their own hand over it. If you have tape and something airtight — a plastic wrapper or bag — you can improvise a cover, but it is hard to do well. Unconscious and breathing: recovery position. Conscious: let them find a position of comfort, often sitting up. Keep watching the breathing until EMS arrives. Civilian guidelines differ on chest seals, and some do not prefer a vented seal.¹¹

▾Does a chest seal belong on a patient being ventilated with a bag?

Not routinely. The National Association of EMS Physicians states EMS may consider a vented seal in spontaneously breathing patients with an open pneumothorax, but that in patients receiving positive-pressure ventilation chest seals may be harmful and are not recommended.¹⁴

▾How should I store it?

Sealed in its pouch at 15–27 °C (59–80 °F), per the label.⁴

▾Seal alone or the Chest Trauma Kit?

The SENTINEL Chest Trauma Kit packs two Sentinel seals with a Dart™ 14-gauge × 3.25 in. needle/catheter for chest decompression, a Dart Target™ placement guide and a wipe.¹⁶ Needle decompression is for trained providers; everyone else carries the seals.

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.

FREQUENTLY ASKED QUESTIONS

What makes the Sentinel Chest Seal different from other vented chest seals?

The Sentinel Chest Seal uses a dual-vent technology that channels air and blood through separate pathways simultaneously — reducing the risk that blood accumulation will block the air venting channel, a failure mode observed in some single-channel or single-valve designs. It also uses a 360° Sentinel 10x™ acrylate adhesive base (non-water-based) rather than a hydrogel, which maintains consistent adhesion in the presence of blood, sweat, and water without softening or swelling over extended evacuation periods. The transparent layered design allows wound monitoring after application without seal removal.

Is the Sentinel Chest Seal vented or non-vented?

The Sentinel Chest Seal is vented. It features dual-vent technology designed for the simultaneous release of blood and air from the chest cavity. This vented design is consistent with the CoTCCC-recommended approach for treating open and sucking chest wounds, as specified in the 2024 TCCC Guidelines — which direct responders to apply a vented chest seal to all open chest wounds when available. The vent design minimizes occlusion risk, reducing the need to manually burp or replace the seal.

Can the Sentinel Chest Seal be used alone or is it only part of the SENTINEL Kit?

The Sentinel Chest Seal is available as a standalone product (SKU 20-001) for integration into existing IFAKs and trauma kits. It is also the chest seal component of the SENTINEL Chest Trauma Kit by Combat Medical Systems, which additionally includes the Dart® 14-gauge 3.25" needle decompression catheter and the Dart® Target placement guide. Purchasing the standalone seal allows organizations to configure their own kits or replace individual components without purchasing a complete kit assembly.

How does the Sentinel's acrylate adhesive compare to hydrogel adhesives?

Most chest seals use hydrogel adhesives, which are water-based gel formulations that conform well to skin texture. The Sentinel uses an acrylate-based adhesive, which is not water-based and therefore does not absorb moisture or swell in wet conditions. Published clinical data on the Sentinel indicates it maintains static placement across environmental extremes. The acrylate adhesive is the same general chemistry class used in advanced wound dressings and some surgical drapes. For operators in extremely wet environments (rain, submersion risk), the non-water-based chemistry may provide an adhesion advantage over some hydrogel alternatives.

What are the packaged dimensions of the Sentinel Chest Seal for IFAK planning?

The Sentinel Chest Seal packages at 19.7 × 14 × 1.3 cm (approximately 7.75" × 5.5" × 0.5") and weighs 0.7 oz. The deployed seal measures 20.3 × 15.2 cm. The relatively flat, low-profile packaging is compatible with standard IFAK pouches. For complete chest trauma capability, the Sentinel pairs with the Dart® needle decompression catheter (14G × 3.25") in the SENTINEL Chest Trauma Kit — the kit dimensions are 6.88" L × 1.0" D and weigh 3 oz total.

How does the Sentinel Chest Seal's dual-vent technology reduce vent occlusion?

Single-channel vented seals use one pathway for both blood and air egress. In an active hemorrhage scenario, blood can pool in this channel, blocking air from escaping and effectively converting the seal from vented to non-vented without the provider's knowledge. The Sentinel's dual-vent system provides separate simultaneous pathways for blood and air, so blood drainage does not compete with or block air venting. Per Safeguard Medical product documentation, this design specifically addresses the vent-occlusion failure mode identified in published chest seal research.

Why does the Sentinel use acrylate adhesive rather than hydrogel?

Most chest seals use hydrogel adhesives, which are water-based formulations that provide good initial conformability to skin texture. The limitation of hydrogels in tactical environments is that they can absorb environmental moisture, swell, and lose adhesive strength when exposed to heavy perspiration, rain, or blood-diluted surfaces. The Sentinel's 360° Sentinel 10x™ acrylate adhesive is not water-based and therefore does not absorb moisture or swell. Per Safeguard Medical product documentation, it maintains static placement across environmental extremes — a meaningful advantage in wet-climate operations or when the wound site has significant blood contamination.

Does the Sentinel Chest Seal need to be purchased as part of the SENTINEL Kit or is it available solo?

The Sentinel Chest Seal (SKU 20-001) is available as a standalone individual seal for integration into existing IFAKs. It is also included as the chest seal component of the SENTINEL Chest Trauma Kit, which adds the Dart™ 14 Ga × 3.25" decompression needle and the Dart Target™ placement guide. Per Safeguard Medical product documentation, buying the seal alone allows units to configure the complete chest trauma module independently or augment existing kits that already include a decompression needle.

What does the 360° adhesive ring on the Sentinel mean for application technique?

The Sentinel's adhesive is applied in a full circumferential ring around the wound contact area, rather than covering the entire backing surface or using spot adhesive. This 360° ring ensures a continuous, uninterrupted seal perimeter around the wound, eliminating the potential for air tracking under an incomplete adhesive edge. The ring design is applied by pressing from the wound center outward to seat the adhesive progressively without trapping air. The transparent layered backing allows the provider to confirm the ring is fully seated before releasing pressure.
