The Asherman Chest Seal is a versatile and essential tool used in emergency first aid for a range of chest injuries. Its design and function make it a go-to option for keeping air out of the chest cavity and preventing potentially life-threatening conditions such as tension pneumothorax.
What is the Asherman Chest Seal?
The Asherman Chest Seal is a one-way valve dressing that is applied to a穿透 chest wall wound. It creates a complete barrier that prevents air from entering the chest, effectively controlling any air buildup that may occur due to a pneumothorax. The Asherman Chest Seal is available in a variety of sizes and is typically made from sterile gauze with a pressure-sensitive adhesive on one side.
Why is it Used?
The Asherman Chest Seal is used primarily to manage open pneumothorax and prevent tension pneumothorax in chest wall injuries caused by firearms, stabbings, or other penetrating trauma. Its unique design allows for the escape of air and blood while preventing the re-entry of either, which can be particularly important in cases where air pressure is rapidly increasing within the chest.
How is itApplied?
Applying the Asherman Chest Seal involves cleaning the injury site, preparing the seal, and then applying it to the chest wall. It is important to ensure that the seal is placed over the entire entry hole to effectively block air flow. After applying the seal, you should monitor the patient for any changes in breathing and to assess the need for further action.
Types of Asherman Chest Seals
There are several types of Asherman Chest Seals available, each with its own unique design and features. Common types include the Halo Chest Seal, the Asherman Chest Seal with a Vented Port, and the Rusch Asherman Chest Seal. Each type of seal varies in terms of ease of use, effectiveness, and the presence of additional features such as a flutter valve.
Safety Considerations
Using any chest seal correctly and efficiently is crucial for safety. If the wrong type of seal is used or if the seal is applied incorrectly, it can lead to air leaks around the seal, which can exacerbate a pneumothorax or create a decrease in compression effect due to increased pressure within the chest. Therefore, it is important to carefully follow the instructions for each specific type of seal and to avoid pushing the seal too hard against the skin.
Storage and Handling
It is essential to store the Asherman Chest Seal in a cool, dry place and to handle it with minimal contamination to maintain its effectiveness. If the seal becomes wet or contaminated, it should be discarded and replaced.
