Do vented chest seals prevent tension pneumothorax?

When do you use a vented chest seal?
Development of a tension pneumothorax is a common life threatening complication of an open chest wound. All open chest wounds should be treated by immediate application of a vented chest seal to cover the defect. If a vented chest seal is not available, use a non-vented chest seal.
Are vented chest seals better?
[11] Vented chest seals allow for the release of accumulated air or evacuation of blood and are effective in preventing the re-entry of air through the open chest wound. Non-vented chest seals adhere to the chest, creating a tight seal and do not allow air to escape or re-enter.

In the sucking chest wound, air is sucked into the thoracic cavity through the chest wall instead of into the lungs through the airways. This occurs because air follows the path of least resistance. When the hole in the chest wall approaches 66% of the width of the trachea, a sucking chest wound can occur.

The seal still works as a one-way valve. Sometimes with vented seals, blood can get into the vents and coagulate, plugging the vents. Same rules apply as with non-vented seals: watch your patient. If the patient gets more winded or drowsy, it’s a good sign he or she is developing a pneumothorax.
Can a Hyfin chest seal be used as a vent?
