The invention relates to an on-site medical gas production plant () comprising a unit () for purifying gas, such as air, a first vessel (A) for storing purified gas, and a main gas line () fluidically connecting the gas purification unit () to the said first storage vessel (A). It furthermore comprises a three-way solenoid valve (VA) arranged on the main gas line () upstream of the first storage vessel (A), and furthermore connected to the atmosphere (at) via a vent line (), as well as an operating device () which controls at least the three-way solenoid valve (VA), and at least a first gas analysis device (D) of which a first measurement line () is fluidically connected (at) to the main line (), upstream of the three-way solenoid valve (VA), and which is electrically connected to the said operating device ().

On-site medical gas production plant and associated operating method

The invention relates to a method for operating a plant () for on-site production of medical gas, such as air or oxygen, comprising a main gas line () comprising, in series, a first vessel (A) for storing gas and a second vessel (B) for storing purified gas, and a secondary line () fluidically connected to the main line (), downstream of the first vessel (A) for storing gas, and comprising a third vessel (C) for storing gas, the main gas line () and the secondary line () each supplying at least one gas consumer site (), in particular a network of pipes in a hospital.

Xenon or xenon-containing gases and, where appropriate, an NO source are employed as medicament for cerebral protection. Cerebral protection is defined as reducing or preventing impairments of cerebral function of various causes, but especially secondary to perfusion impairments of unclear etiology. The medicament can be used for cerebral protection for the prophylaxis of impairments of cerebral perfusion and for therapy after cerebral disorders have occurred, irrespective of the cause (e.g. cognitive, sensory or motor in nature).

An anesthesia system has ventilation gas supply flow structure for supplying ventilation gas to a patient. Structure is provided for the exhaled gas and for recycling the anesthetic gas-containing gas. The system uses a mass spectrometer connected to these flow structures to measure the content of at least one gas component in the gases and to control the flow through at least one of the flow structures in accordance with at least one measured value of the gas content.
