Abstract: In a feedthrough device and method of assembly thereof, a body has longitudinally spaced first and second end faces and an inner surface defining a longitudinally extending opening. A conductor extends within the opening and an insulator extends within the opening transversely intermediate the conductor and the inner surface of the body to insulate the conductor from the body. The body has at least one indentation formed longitudinally into at least one of the first and second end faces, with a portion of the inner surface of the body being displaced transversely against the insulator in correspondence with the at least one longitudinal indentation to crimp the insulator and conductor within the opening of the body and maintain a hermetic seal across the feedthrough device.

Abstract: A differential pressure transducer determines pressure differentials between respiratory airflows and ambient airflows. Another determines pressure differentials between respiratory airflows and ambient airflows. And another determines pressure differentials between i) respiratory airflows received from a subject and ii) interface airflows received from an area near a cannula. Corresponding respiratory monitoring methods also determine the same.

Abstract: A cannula receives i) first respiratory airflows and second respiratory airflows into separate chambers, and ii) ambient airflows. Another receives i) first respiratory airflows and second respiratory airflows into separate chambers, and ii) interface airflows. And another i) first respiratory airflows and second respiratory airflows into separate chambers from a subject, and ii) interface airflow from an area near a cannula. Corresponding respiratory monitoring methods receive the same.
