Abstract
The invention relates to a respiratory flow sensor comprising a flow tube, which has a longitudinal axis, a first flow tube portion and a second flow tube portion, comprising a flow resistor, which is disposed between the first flow tube portion and the second flow tube portion in the flow channel, and comprising two ports for extracting the pressure difference generated by the flow resistor. The first port opens into the first flow tube portion via a first connecting line and said first port is disposed at the first flow tube portion. The second port opens into the second flow tube portion via a second connecting line and said second port is disposed at the second flow tube portion. The ports each comprise a connecting line portion, which extends substantially parallel to the longitudinal axis of the flow tube. The openings of the ports are aligned in the same direction.
