A method for creating an atmosphere in an area which adjoins an outwardly open, inner portion of a body of a human being or an animal, where the portion is uncovered and has direct contact with a surrounding atmosphere, the method including the steps of supplying a gas to the area, wherein the gas forms a main component in the atmosphere and includes a substantial amount of carbon dioxide. The gas is supplied to the area in a substantially laminar, substantially continuous flow and in such manner that the gas forces air away from the open portion and prevents air from penetrating the area of the open portion. The atmosphere prevents growth of microorganisms including bacteria and viruses in the area. |
