a pressure adjusting chamber configured to receive said high pressure inlet gas of said primary high-pressure gas source from said first high-pressure gas inlet-outlet portal, said pressure adjusting chamber being configured to dynamically reduce said high-pressure inlet gas to low-pressure outlet gas: at least one dynamically adjustable ambient pressure portal configured to provide ambient pressure to said pressure adjusting chamber; and at least one dynamically adjustable low-pressure gas outlet portal configured to receive said low-pressure outlet gas from said pressure adjusting chamber; wherein said pressure adjusting chamber is configured to dynamically adjust said low-pressure outlet gas to a predetermined outlet pressure in response to a variable ambient pressure receive by said ambient pressure portal; wherein said first high-pressure gas inlet-outlet portal is configured to provide a direct flow path of said secondary high-pressure gas from said second high-pressure gas inlet portal to said primary high-pressure gas source. ### Claim 2 (depends on 1) The high-pressure reducing regulator of claim 1, wherein said outlet pressure is suitable for any one of breathing and powering tools and devices. ### Claim 3 (depends on 1) The high-pressure reducing regulator of claim 1, further comprising a method of dynamically reducing a pressure of said high-pressure inlet gas to said outlet pressure in response to a change in external ambient pressure level. ### Claim 4 (depends on 1) The high-pressure reducing regulator of claim 1, further comprising one or more gas out portals for measuring a pressure level within said first high-pressure gas inlet-outlet portal. ### Claim 5 (depends on 1) The high-pressure reducing regulator of claim 1, wherein said low-pressure gas outlet portal further comprising one or more gas out portals for distributing said low-pressure outlet gas for breathing, and powering tools and devices. ### Claim 6 (depends on 1) The high-pressure reducing regulator of claim 1, wherein said first high-pressure gas inlet-outlet portal is configured to directly communicate said second high-pressure gas from said second high-pressure gas inlet portal to said primary high-pressure gas source. ### Claim 7 (depends on 1) The high-pressure reducing regulator of claim 1, further comprising a housing for including said first high-pressure gas inlet-outlet portal, said pressure adjusting chamber, and said low-pressure gas outlet portal. ### Claim 8 (depends on 7) The high-pressure reducing regulator of claim 7, wherein said ambient pressure portal is defined through said housing and in communication with said pressure adjusting chamber. ### Claim 9 (depends on 7) The high-pressure reducing regulator of claim 7, wherein said second high-pressure gas inlet portal is defined through exterior of said housing. ### Claim 10 A method of using a housing with a high-pressure reducing gas regulator to reduce a high-pressure gas source through a series of pressure reducing chambers to low pressure for distribution through one or more low-pressure gas outlet ports, said method comprising the steps of: a) receiving in a first high-pressure gas inlet-outlet portal a high-pressure inlet gas at a first pressure from a primary high-pressure gas source; b) receiving in said first high-pressure gas inlet-outlet portal a secondary high-pressure gas from a second high-pressure gas inlet portal including a second fitting with a one-way valve connectable to a secondary high-pressure gas, source; c) receiving in a series of pressure reducing chambers said high-pressure inlet gas from said first high-pressure gas inlet-outlet portal, and dynamically reducing said high-pressure inlet gas to low-pressure outlet gas at a second pressure lower than said first pressure; d) communicating said secondary high-pressure gas through said first high-pressure gas inlet-outlet portal and dynamically reducing said high-pressure inlet gas to low-pressure outlet gas at a second pressure lower than, said secondary pressure; e) dynamically adjusting said low-pressure outlet gas to said second pressure in response to a variable ambient pressure receive in said pressure reducing chambers by a ambient pressure portal; and f) providing said low-pressure outlet gas to a dynamically adjustable low-pressure gas outlet portal.
