Abstract
A pressure differential flowmeter for respiratory flow measurement having enhanced signal processing. The non-linear nature of the signal generated by the differential pressure transducer is accommodated over a wide range of flows via a bank of amplifiers having differing gains, while baseline drift is compensated for by a combined analog and digital auto-referencing technique.
