first aid foam

First-aid foam dressings most commonly use polyurethane foam as the absorbent core. Product descriptions may refer to these as foam pads or plain foam dressings.

Foam dressings are commonly processed in a sterile environment and supplied individually wrapped for single use. Labels typically note they are disposable and advise discarding after use.

They use an adhesive backing or a bordered seal plus a semi-permeable or waterproof outer film that allows vapor to escape while keeping fluids contained. The foam core absorbs exudate so the wound remains moist without leaking.

Tracheostomy foam dressings often include a keyhole or fenestrated opening for the stoma, a highly absorbent foam core, and a semi-permeable polyurethane outer film that is waterproof. They are usually sterile, latex-free, cushioned for protection, and intended to support a moist healing environment.

Many foam dressings are produced in a sterile environment and packaged individually for single use. Labels and product information commonly indicate they are sterile, disposable items and advise discarding after use.
