A device has a power source having a high voltage terminal and a low voltage terminal, an oil-free gas compressor, a first molecular sieve, multiple ionized gas generators, an outer metal pipe, an inner metal pipe, a dielectric insulating ceramic sheet, and a gas outlet pipe. The first molecular sieve is connected between the oil-free gas compressor and the ionized gas generators, and is capable of filtering out molecules in the gas except for oxygen. The outer metal pipe and the inner metal pipe are electrically connected to the low voltage terminal and the high voltage terminal respectively. The dielectric insulating ceramic sheet is mounted between the outer metal pipe and the inner metal pipe, and forms an ionizing space, which communicates with the ionizing space, with the outer metal pipe.

A portable respirator as described may include an inflatable bag and a respirator body. The inflatable bag may be arranged to provide air to a patient through a face mask or an endotracheal tube in response to compression/retraction actions applied to the inflatable bag. The respirator body may include a first cover portion and a second cover portion arranged to enclose moving components of the portable respirator and define a substantially circular opening for the inflatable bag to be fitted through, a motor, a pair of levers positioned on opposing sides of the substantially circular opening, and a cam mechanically coupled to the motor and arranged to move the pair of levers in response to a rotation action by the motor such that the pair of levers apply the compression/retraction actions to the inflatable bag fitted through the opening.

Systems and methods are provided for detecting unacceptable accelerations by an anesthetic vaporizer, such as due to drops and mishandling. In one embodiment, a method for an anesthetic vaporizer comprises determining a quantitative acceleration of the anesthetic vaporizer based on acceleration vectors measured by an accelerometer coupled within the anesthetic vaporizer, and outputting an alert responsive to the quantitative acceleration exceeding an acceleration threshold. In this way, drop-related degradation may be identified in a timely fashion.

A first source of medical gas has a generally cylindrical male outlet with a cylindrical bore and a threaded outer cylindrical surface. A flexible cylindrical elastomeric medical gas tubing has an input end with a bushing making a flush abutment with the male outlet at the output orifice. An output end attaches to any of a plurality of medical gas utilizing devices, but preferably with a dampening disperser held in position in the space in the vicinity of a patient's nose and mouth. An annular flange of the input end bushing resides within a central cylindrical bored out region extending through the first end and nearly to the second end of a rotatable connector forming an interior surface of a connector with threads coupling with the threads of the male outlet. The second end is an annular abutment against the annular flange holding the input end tubing bushing against the outlet source and providing an airtight coupling. A gripping means is on the exterior surface of the connector.

A personal breathing apparatus installed in an aircraft that is not fully pressurized, and configured to prevent or treat an adverse physiological event. The personal breathing system is configured so as to prevent, lessen or reverse hypercapnia by (i) facilitating removal of carbon dioxide generated the pilot by controlling pilot ventilation and/or (ii) limiting or decreasing the amount of carbon dioxide generated by the pilot by controlling the amount of oxygen breathed by the pilot.

Described is a composition for ameliorating symptoms of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and/or fibromyalgia (FM) that has few side effects and can be easily produced. Specifically, described is a composition for ameliorating at least one symptom of fatigue, headache, body pain, impaired thinking, impaired concentration, and/or impaired activity level associated with these symptoms caused by ME/CFS and/or FM in a patient, including a hydrogen gas-containing gas as an active ingredient. Also, described herein is a method for ameliorating symptoms such as fatigue, headache, body pain, impaired thinking, impaired concentration, and/or impaired activity levels associated with these symptoms caused by ME/CFS and/or FM in a patient with ME/CFS and/or FM, including administering the composition to the patient.

The present disclosure provides for a control system for a flow therapy apparatus. The control system can control delivery of a fraction of delivered oxygen (FdO2) to a patient. The control system can maintain the FdO2 at a target level during a therapy session. The control system can automatically control an oxygen inlet valve in order to control the flow of oxygen to the patient.
