摘要：
This heat and moisture exchange (HME) material disclosed is used in heat and moisture exchange with respiratory gases. The HME material 500 comprises a plurality of discrete protrusions 510a, as opposed to continuous ridges or corrugations, extending from at least part of one surface of the HME material. The protrusions may be hemispherical, frustoconical, cylindrical, pyramidal, cuboid, hemicylindrical or any combination of these. Each protrusion may also comprise a perforation such that the HME material forms a flap extending from its surface. A method of manufacture using embossing rollers is also disclosed.
