[Principle of solid-frequent oscillo-resistometry]
Abstract
A small device for the oscillatory measurement of both respiratory resistance and residual volume (SIRE-GNOST FD5), introduced in the late 70ies, found wide-spread use. It is working with a constant frequency of 10 Hz and uses a simple signal conditioning to combine the two components of the "complex" respiratory impedance into a single parameter "Ros", thus allowing to plot e.g. Resistance-Volume-Curves.
