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...

Rutter, N., Milner, A. D., and Hiller, E. J. (1975). Archives of Disease in Childhood, 50, 719. Effect of bronchodilators on respiratory resistance in infants and young children with bronchiolitis and wheezy bronchitis. Respiratory resistance was measured using a forced oscillation technique in 16 infants and young children with bronchiolitis and wheezy bronchitis. Measurements were made before...

The main contribution of this paper is the identification of a human driving model based on field measured car-following data, and the verification of the model's performance in a microscopic traffic simulator. We first examined the SAVME database and obtained a well-defined set of data under closing-in and decelerating lead-vehicle scenarios, i.e. the transient manoeuvre starts with a large ra...

Input impedance of the respiratory system is measured by forced oscillation technique (FOT). Multiple prior studies have attempted to match the electromechanical models of the respiratory system to impedance data. Since the mechanical behavior of airways and the respiratory system as a whole are similar to an electrical circuit in a combination of series and parallel formats some theories were ...

The forced oscillation technique (FOT) is a method for non-invasively assessing respiratory mechanics that is applicable both in paralysed and non-paralysed patients. As the FOT requires a minimal modification of the conventional ventilation setting and does not interfere with the ventilation protocol, the technique is potentially useful to monitor patient mechanics during invasive and noninvas...

The design objective of the Cooperative Intersection Collision Avoidance System for Violation (CICASV) project is to create a system that presents a timely and salient in-vehicle warning to those drivers who are predicted, by means of an algorithm, to violate a stop-sign or signal-controlled intersection. An onroad test was conducted to evaluate the CICAS-V using naïve participants to demonstra...

Every year more than six million crashes occur in the USA, killing over 40.000 people and causing more than three millions of injuries [7]. A major part of these crashes are rear-end collisions. Therefore the U.S. Department of Transportation has put a lot of effort in fostering the development of rear-end collision avoidance systems by funding governmental, academic and industrial research gro...

OBJECTIVE Current debates on the bronchodilator response in COPD patients and whether the variation in FEV1 can be considered as an indicator of complete reversibility in such patients motivated us to conduct this study. The objective of the study was to determine the effect of albuterol on the resistive and reactive properties of the respiratory system in COPD patients. METHODS We evaluated ...

INTRODUCTION Recently, multi-ethnic reference ranges for spirometry have been created for use worldwide. In comparison, forced oscillation technique (FOT) reference values are limited to specific equipment and study populations, with current FOT reference ranges created in a Caucasian population. We aimed to develop FOT reference ranges for preschool-aged Mexican children and to compare these w...

We have studied the bronchial hyperresponsiveness (BHR) of children with normal controls and asthma by methacholine inhalation challenge, using a forced oscillation method. Four parameters, respiratory conductance (Grs), bronchial responsiveness (PD35Grs), bronchial sensitivity (Dmin) and reactivity (SGrs) were studied. There were three patterns of dose-response curves identified in this study,...
