Claims13
1-12. (canceled)
A ventilator apparatus, comprising at least one differential pressure measurement path;
- and a differential pressure sensor, wherein the differential pressure measurement path has a flow channel with at least two measurement openings, wherein a volumetric flow rate/differential pressure characteristic curve is realized by the differential pressure measurement path in conjunction with the differential pressure sensor, said characteristic curve lying between a linear curve and a curve describable by a·X1.5+b.
