Item:
Shipway Warm Ether Apparatus

Date of manufacture:
1916

Manufacturer:
Coxeter

Description:
Shipway designed his apparatus in response to concerns that the exposure of the respiratory mucosa to cold ether vapour was injurious.His full apparatus consists of a rubber hand bellows, an ether vaporiser in a warm water bath (75°F) with an inflow tube carrying the pumped air below the level of the ether, a simple Junkers-type chloroform vaporiser and a metal U-tube arrangement carrying the flow of vapour through a thermos flask that was filled with hot water (120°F). Air from the bellows first meets a tap that directs it to the vaporisers or to a bypass. A second tap adjusts the proportion of the gas that is directed towards the chloroform vaporiser. All of the gas channels combine to pass through the heater tube in the thermos and then on to a wire frame mask sheathed in gauze. The exhibit is the ether vaporiser and tap system of the apparatus.The depth of anaesthesia is controlled by the rate at which the anaesthetist pumps air through the system to be delivered, laden with anaesthetic vapour, to the mask.
