Product information
SAM® Chest Seal is engineered to treat, seal, and reseal open chest wounds under most circumstances. After simple and quick application, SAM® Chest Seal sticks relentlessly – through extreme heat or cold, no matter the elements. Meets CoTCCC-preferred features.
SAM® Chest Seal COMBO — Model CS203-EN
Mission-critical occlusive dressings for open chest wounds. The COMBO pack includes 1 Vented TRUFLOW™ Chest Seal + 1 Non-Vented Chest Seal to match real-world scenarios where you may encounter both entry and exit wounds—or need a contingency if vents clog.
In Stock SKU: CS203-EN Meets CoTCCC-preferred features
Extreme-Condition Adhesion
High-tack hydrogel adheres through sweat, blood, hair, water, heat, and cold—then re-seals after “burping.”
TRUFLOW™ One-Way Valve
Raised-dome vent with large side ports helps maintain outward airflow while resisting inward air entry.
Built for Field Realities
Low-profile, conformable backing seals quickly over irregular anatomy; durable packaging fits IFAKs and kits.
What’s in the COMBO Pack?
- 1× Vented TRUFLOW™ Chest Seal
- 1× Non-Vented Chest Seal
- Low-light friendly packaging and quick-tear access
Note: The COMBO (CS203-EN) is designed to support initial management of open/sucking chest wounds with a vented option, plus a non-vented back-up for complex wound patterns or contingency use.
Key Features

- TRUFLOW™ valve (vented seal): Rigid, raised profile with large side vents to facilitate egress of air/blood—even under external pressure (e.g., body armor).
- Hydrogel adhesion: Sticks aggressively to wet, bloody, or hairy skin; can be lifted to vent (“burp”) and re-sealed.
- Conformable backing: Flexible substrate conforms to chest contours for an air- and water-tight seal.
- Gloved-hand ergonomics: Oversized tab and directional cues for rapid placement in low-visibility or high-stress conditions.
- CoTCCC-aligned use: Vented as primary management; non-vented included for contingency scenarios.
Indications
Immediate occlusion of open chest wounds (e.g., penetrating trauma) to help prevent air entrainment and the progression to tension physiology. Vented seal is preferred for initial management; non-vented is used only when a vented option is unavailable or ineffective, with close reassessment.
How to Use (Field Quick-Steps)
- Expose & wipe away gross contaminants quickly if feasible—do not delay sealing.
- Apply on exhalation: Center over wound, press from center outward to eliminate channels, seal edges firmly.
- Prefer the vented seal first. Monitor chest rise, respiratory effort, and mental status.
- If deterioration occurs with a non-vented seal, momentarily lift an edge (“burp”) to allow egress, then re-seal and reassess.
- Follow local protocols for escalation (e.g., needle decompression) when indicated and within scope.
Specifications (At-a-Glance)
- Model: CS203-EN (COMBO: 1 vented + 1 non-vented)
- Adhesive: High-tack hydrogel, re-sealable
- Backing: Flexible, low-profile, occlusive
- Environment: Effective in wet/dirty, hot/cold conditions
- Packaging: Compact, IFAK-ready
Evidence & Training Rationale
- Guideline-aligned: Current prehospital doctrine favors vented chest seals for open/sucking chest wounds; non-vented may be used only when a vented option is unavailable or ineffective, with close monitoring for tension physiology.
- Mechanism of benefit: Rapid occlusion prevents air entrainment; one-way vent helps egress air/blood to reduce the risk of pressure build-up.
- Design notes: TRUFLOW™ raised dome and side ports are engineered to maintain outward airflow even under external pressure.
- Training tip: After application, reassess breathing frequently. If deterioration occurs with a non-vented seal, momentarily lift an edge (“burp”), re-seal, and consider escalation per protocol.
Note: Use “Meets CoTCCC-preferred features” language; do not claim “approved” or “certified.” Always follow agency protocols and scope of practice.
Who It’s For
- Tactical medics, law enforcement, and high-threat EMS
- EMS & Fire Rescue agencies needing robust adhesion across environments
- Industrial, maritime, and remote responders facing heat, cold, moisture, dust, and sweat
FAQs
Why choose the COMBO (CS203-EN) over vented-only packs?
The COMBO provides a vented seal for guideline-aligned initial care and a non-vented seal as a contingency for complex wounds, clogging risk, or when clinical judgment favors a solid occlusive option with close reassessment.
Will it adhere over hair, blood, and wet skin?
Yes. The hydrogel is engineered for difficult surfaces. Wipe quickly if feasible and apply immediately—seal edges firmly.
Can I “burp” the seal?
Yes—when clinically indicated, briefly lift an edge to vent trapped air/blood, then re-seal and reassess continuously.
Recommended Pairings
- 14-ga Needle Decompression Kit (per protocol and scope)
- Trauma Shears + Skin-Prep Wipes for rapid exposure and adhesion
- Compact occlusive mini-seal for secondary/through-and-through wounds
- MED-TAC IFAK/Bleeding Control Kit for a complete response loadout
Compliance & Notes
- Use phrasing: Meets CoTCCC-preferred features (do not state “approved” or “certified”).
- Follow local protocols and training. Some interventions (e.g., needle decompression) require specific authorization.
- This product is intended for trained responders. Always reassess airway, breathing, and circulation after application.
