Abstract: The present invention relates to low concentration synergistic Xenon-Argon gas mixtures argon for use in a method for preventing and/or treating ischemic insults, wherein —the volume proportion of xenon is between 5 and 20%; —the volume proportion of argon is between 5 and 20%; and —the pharmaceutical composition further comprises a gas complement to reach 100% volume proportion; —the method includes comprises restoration of blood flow and the gas mixture is administered to the patient before, during, or after blood flow restoration.

Abstract: The present application relates to methods to administer to a patient a hypothermal inhalation gas composition that includes oxygen and a mixture of inert gases. The mixture of inert gases includes a first compound selected from xenon and argon, and a second compound having hypothermal properties, such as helium. In the methods, a gas composition including oxygen and a mixture of inert gases is selected and the gas composition is administered to the patient at an inhalation temperature of a specified range such that the body temperature of the patient is maintained within a specified temperature range.

Abstract: The present application relates to methods to administer to a patient a thermally neutral inhalation gas composition that includes oxygen and a mixture of inert gases. The mixture of inert gases includes a first compound such as xenon, and a second compound having hypothermal properties, such as helium. In the methods, a thermally neutral inhalation gas composition including oxygen and a mixture of inert gases is selected and the thermally neutral inhalation gas composition is administered to the patient at an inhalation temperature of a specified range such that the body temperature of the patient is maintained at a specified temperature.

Abstract: The invention relates to a medical device (1) for the closed-circuit administration of a gaseous mixture to be delivered to a spontaneously breathing patient, comprising a gas recycling system (4) disposed on a closed administration circuit (2). The recycling system (4) can comprise in particular an input for an exhaled gaseous mixture and an output for the gaseous mixture to be supplied to the patient, the orientation of which defines a direction of circulation (8) from the input to the output, as well as a zone (Z1) for treating the exhaled gaseous mixture (5) capable of retaining carbon dioxide, as well as at least one zone (Z3) for adjusting the composition of the gaseous mixture, in which zone the concentration of each gas forming the gaseous mixture is adjusted to a setpoint value.

Abstract: The present invention relates to an inhalation gas composition including oxygen and a mixture of inert gases, characterized in that said mixture of inert gases comprises a first compound selected from xenon and argon having hyperthermal properties, and a second compound having hypothermal properties, said mixture of inert gases comprising proportions of the first compound and of the second compound such that said mixture of inert gases is hypothermal.
