It is typically intended to be regularly attached and removed by the patient (e.g., before and after sleeping). It may be made of metal [e.g., silver (Ag)] or plastic materials, and some types may have a sideport for connection to an oxygen supply. This is a single-patient device that may be reapplied over a period of time before being discarded.)
