Method and apparatuses for delivering hyperbaric gas and/or treating respiratory illnesses, post covid syndrome(s) and chronic traumatic encephalopathy

A kit for providing hyperbaric oxygen to a plurality of persons in a cabin of an aircraft having an emergency air or oxygen delivery system therein, comprising:

• a) a pressure gauge or regulator configured to measure or regulate a pressure of the hyperbaric oxygen;
• b) a conduit or conduit system configured to transport the hyperbaric oxygen from the regulator to the emergency air or oxygen delivery system;
• c) a plurality of nasal cannulas or face or head coverings configured to provide the hyperbaric oxygen to the persons, wherein each of the face or head coverings includes a gas inlet, a gas outlet, and one or more seals adapted to contain oxygen in the face or head covering at a pressure greater than or equal to ambient pressure;
• and
• d) a plurality of supply tubes or hoses, each configured to transport the hyperbaric oxygen from the emergency air or oxygen delivery system to a unique one of the gas inlets.

An apparatus, comprising:

• a) a face or head covering configured to provide hyperbaric air or oxygen to a patient in need thereof, the face or head covering including a gas inlet, a gas outlet, and one or more seals adapted to contain the air or oxygen in the face or head covering at a pressure greater than or equal to ambient pressure;
• b) a breathing bag operably equipped with an automatic overpressure valve configured to allow gas to escape from the breathing bag when a pressure in the breathing bag exceeds a predetermined threshold;
• c) a CO2 scrubber canister configured to remove CO2 from air or oxygen in the apparatus;
• d) a hose connecting the CO2 scrubber canister and the breathing bag;
• and
• e) an oxygen supply operably connected to the hose, configured to provide the hyperbaric air or oxygen.
