Technical

“Louis Ombredanne (1871-1956) was a Paris surgeon who was interested in pediatrics and plastic surgery. In a 1908 paper he formulated several propositions on the administration of ether. He stated that the ether mixture had to be “more or less restricted,” with a small amount of fresh air added and some air rebreathed. His inhaler was a direct descendant of Clover’s inhaler, which he criticized for its lack of fresh air and its “useless” water chamber. This inhaler remained in use until the 1950s, even, according to one source, being used by Argentinian troops in the Falklands war with Great Britain.” (ref.2) “The inhaler functioned as follows: ether was absorbed on either sponges or felt. A tube open to the air at one end contained a second tube perforated by holes that could be opened by manipulating an air inlet (…). The gases passed from the bag through two “chimneys” into the ether chamber and then to the mask.” (ref.2)
