Abstract
A respiratory flow sensor, which is suitable for use near a patient, covers a broad gas volume flow measuring range with a low breathing flow resistance and good, reproducible measured signal quality at the same time. The respiratory flow sensor has a first air resistance body (3) with a blunt end and with an opposite pointed end. The air resistance body (3) is arranged between the measuring transducer (5), of which there is at least one, and the patient-side end (P) of the respiratory flow sensor. The pointed end of the first air resistance body (3) points toward the measuring transducer (5). A second air resistance body (4) with a pointed end is arranged between the measuring transducer (5), of which there is at least one, and the end of the respiratory flow sensor that is away from the patient. The pointed end of the second air resistance body (4) also points toward the measuring transducer (5).
