A nose mask for administering one or more gases such as oxygen to a human being comprises, in combination, (I) a shell having a front portion, a rear portion and a first opening comprising substantially the entire horizontal area beneath the wearer's nose and (II) a hollow gas delivery tube containing at least one gas delivering and dispersing means. The mask enables a wearer to breathe, eat and converse in a substantially normal fashion while efficiently providing the wearer with a cloud of gas (enriched in the gas or gases being delivered) directly beneath the nose and in front of the mouth of the wearer. The mask is particularly useful in long-term oxygen therapy applications.
