Abstract (en)

[origin: WO9842396A1] The invention provides a workstation for delivering oxygen-enriched air to an anaesthetized patient, comprising: means (1) for entraining ambientair from a room into one or two variable volume working chambers (4) by increasing the volume of the working chamber(s) (4); means (8) for mixing oxygen from a pressurized source with the entrained ambient air; and means (3, 16, 17) for delivering the entrained mixture intermittently or as continuous flow from the working chamber(s) (4) to a patient by decreasing the volume of the working chamber(s) (4). The apparatus lacks the complexity of conventional anaesthesia workstations, provides for the delivery of suitable humid room air to the patient's airways, and is suitable for use with intravenously administered anaesthetics.
