The mechanical impedance of the respiratory system defines the pressure profile required to
drive a unit of oscillatory flow into the lungs. Impedance is a function of oscillation frequency …

Since its introduction in the 1950s, the forced oscillation technique (FOT) and the
measurement of respiratory impedance have evolved into powerful tools for the assessment …

In science, engineering and economics, decision problems are frequently modelled by
optimizing the value of a (primary) objective function under stated feasibility constraints. In …

Experience gained during a ten-year long involvement in modelling, program ming and
application in nonlinear optimization helped me to arrive at the conclusion that in the interest …

In nine anesthetized and paralyzed cats, the mechanical impedances of the total respiratory
system (Zrs) and the lungs (ZL) were measured with small-volume pseudorandom forced …

Because of the wide utilization of rodents as animal models in respiratory research and the
limited data on measurements of respiratory input impedance (Zrs) in small animals, we …

Developed over six decades ago, pulmonary oscillometry has re‐emerged as a noninvasive
and effort‐independent method for evaluating respiratory‐system impedance in patients with …
