What is the purpose of an occlusive dressing?

The purpose of an occlusive dressing is to form an airtight seal over a wound. This type of dressing is particularly important for managing certain injuries, such as open chest wounds or large lacerations, because it helps to prevent air or contaminants from entering the wound, which can lead to complications like infection or further damage. By creating a barrier, an occlusive dressing also helps in maintaining a moist environment for healing and can minimize pain by reducing exposure to external elements. The effectiveness of an occlusive dressing is crucial in emergency medical situations, as it helps to stabilize the patient until they can receive further treatment.
