A tracheostoma plaster is also called baseplate.
A tracheostoma plaster is placed around the tracheostoma containing a filter (cassette). How often a plaster needs to be replaced depends on individual situations, on mucus production and the type of plaster used.
A tracheostoma plaster can stay in place for a few days, but is generally replaced daily. The plaster should in all cases be changed when it becomes partially detached or if the skin surrounding the stoma and the plaster is soiled with mucus. One or more filters can be used daily, depending on mucus production.
The tracheostoma plaster is placed on the clean skin surrounding the tracheostoma. Importantly, skin should be allowed to dry before placement, see also placement protocol. If plasters and/or filter cassettes are not tolerated, it is recommended to protect the stoma against cold and dust by wearing a scarf or band (e.g. a single-use band or washable protective band). A tube or button can also be used.
