Respiratory mechanics studied by forced oscillations during artificial ventilation.
Potential advantages of the forced oscillation technique over other methods for monitoring total respiratory mechanics during artificial ventilation are that it does not require patient relaxation, and that additional information may be derived from the frequency dependence of the real (Re) and imaginary (Im) parts of respiratory impedance. We wanted to assess feasibility and usefulness of the ...
متن کاملExploring respiratory mechanics by forced oscillations: principles and pitfalls.
Submitting a physical system to forced oscillations is a very general approach to investigation of its structure and/or properties. Its application to respiratory mechanics was first proposed by DuBors et al. in 1956 [1], but it has also been used in other fields of respiratory physiology, e.g. to investigate the control of breathing and the response to exercise. As used in respiratory mechanic...
متن کاملAssessment of respiratory mechanics with forced oscillations in healthy newborns.
BACKGROUND Lung function data in healthy newborn infants are scarce largely due to lack of suitable techniques, although data for developmental and prenatal exposure studies are much needed. We have modified the forced oscillation technique (FOT) for the measurement of respiratory mechanical impedance (Zrs) in unsedated sleeping infants in the first 3 days of life. METHODS Zrs was measured du...
متن کاملDetection of Novel Respiratory Mechanics Parameters by Means of Forced Oscillations
The objective of this paper is to present recent results within an investigation on human respiratory mechanics. The overall aim is to provide a fast method for identification of airway mechanics, in order to assist the medical staff in obtaining a diagnosis of the patient. Some ideas for a novel detection of respiratory mechanics parameters are presented, as well as preliminary experimental re...
متن کاملEstimating Respiratory Mechanics with Constant-phase Models in Healhty Lungs from Forced Oscillations Measurements
Demanding minimal cooperation from the patient, the forced oscillation technique (FOT) is an attractive non-invasive lung function test. Its successful application to assess respiratory mechanics makes it an interesting topic for further investigations. Recent trends in signal processing and modelling techniques play a significant role in improving the assessment of input respiratory impedance....
