摘要:
A differential pressure transducer determines pressure differentials between respiratory airflows and ambient airflows. Another determines pressure differentials between respiratory airflows and interface 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.

A cannula receives respiratory airflows and ambient airflows; a differential pressure transducer determine pressure differentials between the respiratory airflows and the ambient airflows; and a ventilator responds to the pressure differentials. Another receives respiratory airflows and interface airflows; a differential pressure transducer determine pressure differentials between the respiratory airflows and the interface airflows; and a ventilator responds to the pressure differentials. And another receives respiratory airflows from a subject and interface airflows from an area near a cannula; a differential pressure transducer determine pressure differentials between the respiratory airflows and the interface airflows; and a ventilator responds to the pressure differentials. Corresponding respiratory monitoring methods receive, determine, and control the same.
