Apparatus and systems for optimizing nitric oxide production and consumption by subjects

An apparatus for optimizing nitric oxide production and consumption by a subject, comprising:

• a mask configured for deployment over a nose and a mouth of a subject, the mask comprising:
• a first mask portion configured for airtight deployment over the nose of the subject, the first mask portion comprising:
• a valve configured to, during operation,:
• pass air from an ambient environment therethrough and into the first mask portion;
• and
• prevent air within the first mask portion from being passed therethrough to exit the first mask portion;
• and
• a seal configured to prevent air from entering or exiting the first mask portion except through the first mask portion valve;
• a second mask portion configured for airtight deployment over the mouth of the subject, the second mask portion comprising:
• a valve configured to, during operation,:
• prevent air from being passed therethrough to enter into the second mask portion;
• and
• pass air from within the second mask portion therethrough and out into the ambient environment;
• and
• a seal configured to prevent air from entering or exiting the second mask portion except through the second mask portion valve;
• wherein the first mask portion and the second mask portion are hermetically separate.

A system for optimizing nitric oxide production and consumption by a subject, comprising:

• a plurality of nose plugs, wherein at least a portion of each nose plug is configured for airtight deployment within a respective nostril of the nose of the subject, wherein each nose plug comprises:
• a respective valve configured to, during operation,:
• pass air from an ambient environment therethrough and into the respective nose plug within the respective nostril of the nose of the subject;
• and
• prevent air within the respective nostril of the nose of the subject from being passed therethrough to exit the respective nose plug;
• a mouthpiece configured for airtight deployment over the mouth of the subject, the mouthpiece comprising:
• a valve configured to, during operation,:
• prevent air from being passed therethrough to enter into the mouthpiece;
• and
• pass air from within the mouth of the subject therethrough and out into the ambient environment;
• a seal configured to prevent air from entering or exiting the mouthpiece except through the mouthpiece valve;
• wherein the plurality of nose plugs and the mouthpiece are hermetically separate.
