The Halo Chest Seal is a  high performance occlusive dressing designed to treat penetrating chest wounds along with securing other wound dressings. The patented hydro-gel provides superior adhesion to the wound area even when moisture, pleural fluids or blood is present. It will work on patients with heavy perspiration or very wet environments. The highly aggressive tack adhesive of the hydro-gel will enable the dressing to conform and hold to the patient's body.

Halo Chest Seals also perform without loss of adhesion in extreme temperatures. Performance tested from -40° to 150° (-40°C to 65°C). The Halo packaging includes two seals per pack. Unique package provides four notched corners for easy opening but if opened from the top, package can be resealed if both seals are not used in treatment.

TCCC Guideline - Management of Open or Sucking Chest Wounds

This guideline supports the total occlusive property of the Halo Seal product. Tactical Field Care and CASEVAC Care - Breathing: All open and/or sucking chest wounds should be treated by immediately applying an occlusive material to cover the defect and securing it in place. Monitor the casualty for the potential development of a subsequent tension pneumothorax.

The HALO Advantage

Outer Tape Edge

  • Tape edge is more forgiving when handling with gloved or bare hands.
  • Studies show that the outer tape edge has a wider operating temperature range and performs extremely well in freezing and elevated temperatures

Size and Shape

    One of the few chest seals that actually gives you 2 seals. Folds easy for storage in cargo pocket or first aid kit.

    Good size and fold nicely to fit into smaller kits. Comes as a pair which is always appreciated. Looks and feels of good quality, i just hope i never have to use one.

    All the features you want

    It's very unfair to review a product that I haven't actually used on a human to treat a sucking chest wound. That being said, military professionals rave about the HALO. It appears to have all the convenient features you want in a chest seal. It's great that it comes with two - entry and exit wound. It folds nicely and fits in both my ITS tallboy IFAK and HSGI bleeder.
