Abstract
A breathing apparatus (10) including a mouthpiece (13) and a carbon dioxide removal area (18) disposed between the mouthpiece and an air reservoir chamber (19). The chamber is preferably filled with a foam material (27) and is further in communication with ambient air (29) to enable mixing with expired air within the chamber (19). The breathing apparatus (10) is useful for simulating the lower partial pressure of oxygen at high altitude, hence it may be used by athletes for simulating “living at altitude”.
Claims12
A breathing apparatus (10) including a container (11), mouthpiece means (13) opening into the container, carbon dioxide removal means (18) disposed in an airflow between the mouthpiece means and an air reservoir means (19), the air reservoir means being disposed at least partially between the removal means (18) and an ambient air inlet (24), means to adjust the effective volume of the air reservoir means (19) whereby air expirated from a user can flow through the removal means into the reservoir means and mix with ambient air, such mixture to be inspired by the user through said mouthpiece (13) via said removal means (18).
A method of breathing including the steps of expirating air through carbon dioxide removal means (18) into a reservoir means (19) that is coupled with an ambient air inlet (24), the effective volume of said reservoir means (19) being adjustable by moving the inlet (24) in relation to the removal means (18).
A breathing apparatus (10) including a mouthpiece (13), an inlet port (24, 29) for ambient air, a carbon dioxide removal means (18) disposed in an air flow between the mouthpiece (13) and a chamber (19) including a foam material (27) therewithin, said chamber being disposed at least partially between the removal means (18) and the inlet port (24 29), and wherein air expirated through said mouthpiece/removal means by a user is mixed with ambient air in the chamber (19) and inspired back through the same removal means/mouthpiece.
