Hyfin Chest Seal Review

There are many reasons a sucking chest wound can happen, and none of them are expected or pleasant. It can happen from stabbing, gunshot, industrial related injury or accidental puncture wound. The discussion isn’t pleasant, but the increasing incidents of mass shootings, even bombings has compelled civilian EMS providers to treat combat type injuries. Hyfin Vent Chest Seal is extremely helpful in these situations. It’s a simple, perfectly sized and vigorously sticky chest seal which works with sweaty (or bloody) skin well. A great addition to your first aid kit box, Hyfin vented chest seal comes with some advantages, like dealing with tension pneumothorax, which normal occlusive dressings can’t provide.

What Is Tension Pneumothorax?

A sucking chest wound is a hole in the chest, which creates a third way for air along with your mouth and nose. When the chest cavity is expanded during breathing, air goes into the hole. This may be dangerous, often deadly because that lead to tension pneumothorax. A tension pneumothorax is a collapsed lung that is leaking air, gathering them between the chest wall and lung. An air tension then builds up which pushes the lungs to the other side. Often, this results in low blood pressure and the victim goes to shock.

There are some signs of tension pneumothorax:

  1. Shortness of breath. Veins, lips or fingers turning blue
  2. Uneven chest, one side looking bigger than the other.
  3.  Neck veins swelling, no lung hums on one side.

If a tension pneumothorax is building, its necessary to release the trapped air before it leads to shock.

What Is A Vented Chest Seal and Why Is It Necessary?

Usually, the initial treatment of chest wound is done by generic adhesive dressing, the same type used to cover IV sites. These dressings are usually available in the ambulance. They cover up the wound, prevent air flow through the chest wound and stop blood loss.

The problem with these dressings are, they completely seal the wound. They stop air from getting in, but they also fail to deal with tension pneumothorax.

To address this problem, companies like Hyfin researched and developed vented chest seals. A vented chest seal works as a one-way valve. It doesn’t let the air inside while allowing drainage for the trapped air.

For a vented chest seal to work well, it must have two main features. It should be tacky enough to stick on a sweaty, bloody skin. Also, it should have a one-way valve mechanism that works well.

How To Use A Chest Seal?

02. If you find a wound, instantly put your gloved hand above it. Open the vent seal pack.

03. Before applying the seal, wipe and clean the blood, sweat, wreckage from the wounded area. Use the gauge that comes with the seal. Clean and place your gloved hand again, do not keep the wound open.

04. Pull the red tape to peel the vent seal, then apply the sticky side on the wound. Make sure the seal is centered over the wound.

05. Check if the seal is glued properly, make sure no air is going in during inhalation. Finally, check if the vented ports are open and allowing excess air to escape. Repeat the process if there’s any exit or additional wound.

06. Sometimes with vented seals, blood can get into the way and clog the path. Observe through the transparent seal for any incidents like that. If the victim shows increasing sign of pneumothorax, remove the seal and let the air exit.
