Abstract
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.
