A Fan-Based, Low-Frequent, Forced Oscillation Technique Apparatus
IEEE Transactions on Instrumentation and Measurement, 2014The forced oscillation technique (FOT) is a noninvasive method to characterize the respiratory impedance (Z). Z is defined as the frequency-dependent ratio between pressure and flow. The FOT determines Z by superimposing small amplitude (in the order of 0.1 kPa) pressure oscillations on the normal breathing.

The forced oscillation technique in children with respiratory disease
Pediatric Pulmonology, 1985AbstractThe single‐frequency forced oscillation technique was used to estimate the total respiratory impedance, resistance, and reactance at 2, 4, and 12 Hz of children who had cricoid stenosis (CS; n = 11), provoked bronchoconstriction (PB; n = 6), or cystic fibrosis (CF; n = 13).

Forced oscillation technique in infants and young children
Paediatric Respiratory Reviews, 2005Due to its non-invasive character, the forced oscillation technique has gained importance in clinical research in infants and young children. Standardisation has enabled systematic and comparable measurements to be made in different laboratories throughout the world.

Measurements of dynamic stability derivatives using direct forced oscillation technique
ICIASF 2001 Record, 19th International Congress on Instrumentation in Aerospace Simulation Facilities (Cat. No.01CH37215), 2002The subject of the experimental investigation presented in this paper is to measure the dynamic stability derivatives of a generic combat aircraft model in the Ankara Wind Tunnel by using the direct forced oscillation technique. The model, used for the tests is the AGARD, Standard Dynamic Model (SDM).

A modified forced oscillation technique for measurements of respiratory resistance
Journal of Applied Physiology, 1977We present a modification of forced oscillation technique for automated determination of total respiratory resistance during inspiration. The modifications consist of a computerized signal averaging and an optimization technique in the assessment of the resistance value.

Nasal airflow resistance measurement: forced oscillation technique versus posterior rhinomanometry
European Respiratory Journal, 1998This study was designed to determine whether nasal airflow resistance (Rn) which is nonlinear during tidal breathing, can be assessed by the forced oscillation (FO) technique. Rn values obtained by the FO technique and extrapolated to 0 Hz (Rn,FO) were compared to those assessed by posterior rhinomanometry at maximal tidal inspiratory flow (Rn,m), at a

Total respiratory resistance (Rrs) was measured by the application of a sine wave of airflow to the mouth at an oscillation frequency of 10 Hz. The instrument used was the Siemens Siregnost FD5. The Rrs data were correlated with height, age, sex, and weight in 73 patients and 29 healthy subjects.

Understanding Pulmonary Mechanics Using The Forced Oscillations Technique
2007The lung is a marvelously over-designed mechanical ventilation system. It is capable of sustaining substantial injury or alteration while still maintaining life-sustaining blood gas levels. Nevertheless, these alterations often lead to compromised lung function and breathing discomfort.
