Pathophysiology of a sucking chest wound (Open Pneumothorax)¶

Under normal physiological conditions, when your diaphragm contracts downward and your intercostal muscles pull your ribcage outward, intra-thoracic pressure drops slightly below outside atmospheric pressure (from -4 down to -8 \(\text{cmH}_2\text{O}\)). Because the chest wall is completely sealed, the only pathway for air to enter the chest is down the mouth, trachea, and bronchi, inflating both lungs effortlessly.

The "Two-Thirds Tracheal Diameter" threshold¶

An adult human trachea has an internal diameter of roughly 18 to 24 millimeters (0.7 to 0.95 inches). If a knife blade, high-velocity rifle round, shotgun blast, or impaled fence spike creates an open hole through the chest wall whose cross-sectional diameter is two-thirds the diameter of the trachea (roughly 12 to 15 millimeters / 0.5 to 0.6 inches) or larger, the laws of fluid dynamics dictate that air follows the path of least resistance:

1. Because the short hole through the ribcage offers far less airway resistance than the long, branching bronchial tree, every time the victim tries to inhale, outside room air rushes directly through the hole in the chest wall into the pleural space rather than coming down the windpipe into the lungs.
2. As room air fills the pleural space on the injured side, the lung on that side collapses completely and cannot exchange oxygen.
3. Even worse, as the victim inhales and exhales, stale carbon-dioxide-rich air sloshes back and forth uselessly between the collapsed lung and the healthy lung (Pendelluft or "pendulum air"), while the mediastinum (containing the heart and vena cava) wobbles side to side (mediastinal flutter), rapidly exhausting the patient and causing severe hypoxia and hypercapnia.

Classic signs of an open sucking chest wound¶

• Audible sucking, hissing, or slurping sound coming from the chest or back wound each time the casualty gasps for air.
• Frothy, bright pink or red blood bubbling or sputtering out of the wound during exhalation or coughing (unlike dark red venous oozing or bright red arterial spurting from an arm wound, frothy bubbles prove air from the respiratory tract or pleural space is mixing with blood).
• Subcutaneous emphysema: Air forced under the skin of the chest wall and neck creates a strange, crackling "Bubble Wrap" or "Rice Krispies" sensation (crepitus) when you press your fingers lightly on the skin around the collarbone or ribs.

Step-by-step technique: Applying a Vented Chest Seal or Three-Sided Dressing¶

The immediate goal of first aid for an open chest wound is to convert an open pneumothorax into a simple vented pneumothorax: blocking outside air from sucking in during inhalation while allowing trapped internal air and blood to escape during exhalation.

Method A: Commercial Vented Chest Seal (Gold Standard: CoTCCC & First Aid Guidelines)¶

Modern trauma kits carry purpose-built Vented Chest Seals (such as the HyFin Vent, SAM Chest Seal, Russell Chest Seal, Halo Vent, or Bolin/Asherman seal). These feature an aggressive medical hydrogel adhesive pad equipped with either a raised one-way dome valve or multiple laminar-flow vent channels that let air and blood escape outward while sealing flat against the skin when the patient inhales.

1. Expose the wound and check the back: Cut the shirt away completely. Always check the back and armpits for an exit wound; if there are two holes (an entry and an exit), apply a vented chest seal to the primary sucking hole and a second seal (vented if available) to the exit hole.
2. Wipe the skin around the wound completely dry: This is the step most rescuers forget under stress. Even the best hydrogel adhesive will slide right off skin coated in wet blood, sweat, mud, or rainwater. Use a dry gauze pad inside the chest seal package to briskly wipe a 10-centimeter (4-inch) circle of skin around the hole as dry as possible.
3. Peel the backing and apply at the end of exhalation: If the patient is conscious, ask them to breathe out (exhale) and pause for one second (exhaling pushes extra air out of the pleural space before you seal it). Center the one-way valve or laminar vent channels directly over the hole and press the adhesive firmly from the center outward to eliminate wrinkles.

Method B: Improvised Three-Sided Occlusive Flutter-Valve Dressing¶

If you do not have a commercial vented chest seal in your first aid kit, you must construct a Three-Sided Occlusive Dressing:

1. Find a piece of completely airtight, non-porous flexible material: Plain gauze pads do not work by themselves because air passes right through woven cotton. Use one of the following airtight barriers:
2. The clean inner foil or plastic wrapper of a sterile gauze dressing or AED defibrillator pad.
3. A square cut from a heavy-duty plastic freezer bag, nitrile glove package, or clean plastic cling wrap.
4. Sterile petrolatum (Vaseline) gauze covered with a layer of foil or plastic.
5. In the first 10 seconds before materials are ready: Slap your gloved palm directly over the sucking hole during exhalation, lifting the heel of your hand slightly when the patient exhales to let air out, and sealing it flat when they inhale.
6. Cut the plastic square at least 5 centimeters (2 inches) wider than the wound on all sides: If the plastic is too small, the suction of inhalation will pull the entire piece of plastic into the wound hole.
7. Wipe the surrounding skin dry and place the plastic over the wound as the patient exhales.
8. Tape THREE sides completely airtight, leaving the BOTTOM corner or fourth side completely UNTAPED:
9. Apply wide medical tape or duct tape completely overlapping the top edge, left edge, and right edge of the plastic square so no air can leak under those three edges.
10. Leave the bottom edge (or the lowest gravity-dependent corner) completely free of tape.
11. How the flutter valve works: When the patient inhales, negative pressure inside the chest pulls the loose plastic sheet flat and wet against the skin, sealing the hole airtight so outside air cannot enter. When the patient exhales or coughs, positive pressure inside the chest pushes trapped air and blood out from underneath the untaped bottom edge like a one-way flapper valve.

Recognizing and treating Tension Pneumothorax ("Burping the Seal")¶

A tension pneumothorax is an immediately fatal mechanical catastrophe that can develop either from a closed rib fracture / lung laceration or when an open chest wound dressing becomes clogged or sealed on all four sides.

How tension pneumothorax kills (Obstructive Shock)¶

With every breath, 50 to 100 milliliters of air leaks out of the lacerated lung into the trapped pleural space and cannot escape back into the bronchi or out through the chest wall: 1. Pressure inside the injured side of the chest rises from negative (-5 \(\text{cmH}_2\text{O}\)) to strongly positive (+15 to +30 \(\text{cmH}_2\text{O}\)). 2. The injured lung is crushed down into a tiny airless ball at the hilum, while the diaphragm on that side is pushed downward into the abdomen. 3. The expanding pocket of high-pressure air shoves the entire mediastinum (heart, aorta, superior vena cava, inferior vena cava, and trachea) sideways into the uninjured side of the chest, compressing the remaining good lung. 4. The fatal step: Because the thin-walled superior and inferior vena cava return deoxygenated blood to the right side of the heart at very low venous pressures (only 2 to 8 mmHg), the mediastinal shift kinks both great veins like a bent garden hose. Blood can no longer enter the heart (preload drops to zero), cardiac output plummets, and the patient suffers Pulseless Electrical Activity (PEA) cardiac arrest from pure mechanical obstructive shock.
