Abstract

A system includes a pressure regulator including a housing, an inlet for connection to a pressurized gas comprising oxygen, and at least one energy transfer element. The system further includes a respiration facepiece including at least one seal system to form a sealing engagement with the face of a user to encompass the nose and mouth of the user, thereby creating a volume of sealing engagement between the respiration facepiece and the user, an opening into the volume of sealing engagement of the respiration facepiece in communicative connection with an interface for removable attachment of the pressure regulator to the respiration facepiece, and an inspiration port in fluid connection with the interface and in fluid connection with the volume of sealing engagement. The pressure regulator interface includes at least one cooperating energy transfer element such that energy can be transferred between the at least one energy transfer element and the at least one cooperating energy transfer element to transfer at least one of data or power into the volume of sealing engagement.
