The present invention relates generally to the fields of treating psychiatric disorders, in particular, anxiety disorders including post-traumatic stress disorder (PTSD) in subjects, e.g., human subjects, by administering a xenon and/or argon containing composition. Treatments can also employ psychotherapy in combination with administration of xenon and/or argon, alone or in combination with additional psychotherapeutic medications to treat the anxiety disorder and reduce a symptom of the anxiety disorder in the subject.

A portable gas delivery system 10 may generally comprise a gas container 20, a regulator 30, an adapter 40 to couple the regulator 30 to the container 20, and a tube or cannula 50 and/or a mask 60 fluidly connected to the container 20. Methods of making and using the portable gas delivery system are also described.

This disclosure relates to methods and apparatus for treating diseases and conditions of the colon and alimentary canal which are associated with obligate anaerobic microorganisms, and particularly, for treating Clostridioides difficile infection. The method and apparatus provide for continuous administration of intraluminal oxygen to the rectum, colon, and cecum to maintain oxygen in those environments at levels toxic to obligate anaerobic microorganisms such as Clostridioides difficile.

A process includes removing air bubbles from extracorporeal blood via chemical entrapment of nitrogen (N.sub.2) gas.

An oxygen concentrator is provided with a controller for recovering an oxygen concentration to a level suitable for treatment in a short period of time by selecting an optimum purge time corresponding to the deterioration state of an adsorbent. The judgment of moisture-absorption deterioration is performed when the detected value of the oxygen concentration sensor is equal to or less than a control value of the oxygen concentration in the oxygen-enriched gas and the detected value of the pressure sensor is equal to or more than an adsorption pressure at which the oxygen concentration increases significantly before and after the control to reduce the purge time, and control of reducing a time for the purge step shorter than a preset time is performed.

An example aerosol delivery device includes a mouthpiece having an airflow outlet, and an airflow passage extending between an airflow inlet and the airflow outlet. The example aerosol delivery device further includes a housing configured to receive a cartridge that includes an aerosolizable substance and a vapor element configured to heat the aerosolizable substance, and an internal power source configured to provide electrical power. The example aerosol delivery device further includes a controller coupled to the internal power source to receive a portion of the electrical power and configured to, when the cartridge is installed at the housing, cause the vapor element of the cartridge to heat the aerosolizable substance to release an aerosol into the airflow passage during an inhalation through the airflow outlet, and a connector configured to receive power from an external source to recharge the internal power source.
