BACKGROUND Relationships between early deficits of lung function, infant airway pathology and outcome in symptomatic infants are unclear. A study was undertaken to determine the associations between early lung function, airway histology and inflammation in symptomatic infants with the continuance of respiratory symptoms, lung function and subsequent use of inhaled asthma medication at the age o...

We propose a forced oscillation test modality for detecting upper airway obstruction (UAO) as an alternative to spirometric UAO indices in patients with tracheal stenosis. From oscillometry performed at different breathing flow rates, airway resistance at 5 Hz was determined at 0.5 l/s (R), and flow dependence of resistance was computed as the regression slope of resistance vs. flow up to 1 l/s...

background: the purpose of this study was to calculate and compare the specificity and sensitivity of impulse oscillometry (ios) as a new technique in the detection of airways dysfunction by means of a simple pulmonary function test in chemical warfare injured cases suffering from respiratory diseases.   methods: the study was performed prospectively in 100 patients, who complained of dyspnea a...

OBJECTIVE To evaluate the outcome of a secondary intervention conducted with infants at risk for asthma. DESIGN Families of wheezing infants were randomized to a 1-year intervention or control group; outcome evaluation occurred from April 1, 2000, through September 30, 2003, when children reached 4 years of age. SETTING Home intervention and clinic evaluation. PARTICIPANTS A total of 149 ...

INTRODUCTION Abnormality in distal lung function may occur in obesity due to reduction in resting lung volume; however, airway inflammation, vascular congestion and/or concomitant intrinsic airway disease may also be present. The goal of this study is to 1) describe the phenotype of lung function in obese subjects utilizing spirometry, plethysmography and oscillometry; and 2) evaluate residual ...

BACKGROUND Impulse oscillometry (IOS) is a non-demanding lung function test. Its diagnostic use may be particularly useful in patients of advanced age with physical or mental limitations unable to perform spirometry. Only few reference equations are available for Caucasians, none of them covering the old age. Here, we provide reference equations up to advanced age and compare them with currentl...

BACKGROUND A higher prevalence of airflow limitation (AL) has been described in patients with ischemic heart disease (IHD). Although small airway dysfunction (SAD) is an early feature of AL, there is little information about its occurrence in IHD patients. Our objective was to describe the prevalence of SAD in IHD patients, while comparing patient-related outcomes and future health risk among I...

A small gain approach for stability analysis of cooperative network-based force reflecting teleoperator systems is presented. The approach is based on a new version of inputto-output stability (IOS) nonlinear small gain theorem that is applicable to stability analysis of large-scale network-based interconnections. Using the small-gain theorem presented, we show that stability of the cooperative...

The adoption of inter-organisational system (IOS) has become important for many organisations because of its many benefits, which can be categorised into operational, managerial and strategic benefits. While some organisations have gained many benefits, some have experienced very limited benefits from IOS adoption. Existing studies have identified a number of factors affecting the achievement o...
