Abstract

A device for monitoring respiration comprises a duct, a flow restricting element in the duct, and a pressure sensor arranged in the duct. The pressure sensor measures a pressure drop across the flow restricting element as a pressure difference between a pressure at a location in the duct on a first side of the flow restricting element and a substantially constant pressure on a second side of the flow restricting element opposite the first side.
