On the basis of goal/expectation theory, it was predicted that just as in interpersonal relationships, cooperation in social dilemma groups would increase only if both trust was high and group members had a common goal of cooperation. Introducing new measures of both these two processes to the social dilemma arena, the goal of mutual cooperation was assessed by the process of self–other merging...

BACKGROUND The role of small airway obstruction in the clinical expression of asthma is incompletely understood. OBJECTIVE We tested the hypotheses that markers of small airway obstruction are associated with (i) increased asthma severity, (ii) impaired asthma control and quality of life and (iii) frequent exacerbations. METHODS Seventy-four adults with asthma and 18 healthy control subject...

OBJECTIVE Impulse oscillometry (IOS) is an evolving technology for the diagnosis and followup of patients with asthma. Our objective is to review the findings on patients who underwent both spirometry and IOS during clinical evaluations of their asthma. The goal was to retrospectively evaluate IOS during the initial diagnosis and followup of patients with asthma in comparison with spirometry. ...

INTRODUCTION Spirometry, which is a basic diagnostic tool of the respiratory system, may cause problems to patients of advanced age because of required cooperation and specific respiratory manoeuvres. Impulse oscillometry (IOS) may be an interesting alternative for spirometry as the examination is made during quiet breathing and gives information about resistive properties of the respiratory sy...

STUDY OBJECTIVE The efficacy of using impulse oscillometry (IOS) as an indirect measure of airflow obstruction compared to spirometry after exercise challenges in the evaluation of exercise-induced bronchoconstriction (EIB) has not been fully appreciated. The objective was to compare airway responses following room temperature and cold temperature exercise challenges, and to compare whether IOS...

OBJECTIVE To evaluate peripheral respiratory system resistance and reactance (Rrs and Xrs, respectively) in obese individuals. METHODS We recruited 99 individuals, dividing them into four groups by body mass index (BMI): < 30.0 kg/m2 (control, n = 31); 30.0-39.9 kg/m2 (obesity, n = 13); 40.0-49.9 kg/m2 (severe obesity, n = 28); and ≥ 50.0 kg/m2 (morbid obesity, n = 13). Using impulse oscillom...

A variety of methods have been proposed to noninvasively assess arterial stiffness using single or multiple oscillometric cuffs. A common pitfall of most of such methods is that the individual-specific accuracy of assessment is not clearly known due to an insufficient understanding of the relationships between the characteristics of cuff oscillometry and cardiovascular properties. To provide a ...

This study examines the relationship of respiratory system resistance (R(rs)) and reactance (X(rs)) measured by forced oscillometry with transpulmonary resistance (R(L)) measured by oesophageal manometry. Simultaneous forced oscillometry using a single frequency of 5 Hz and oesophageal manometry were performed on five asthmatics during bronchoprovocation. The data obtained were used to derive p...

Blood pressure (BP) is one of the most important monitoring parameters in clinical medicine. For years, the cuff-based sphygmomanometer and the arterial invasive line have been the gold standards for care professionals to assess BP. During the past few decades, the wide spread of the oscillometry-based BP arm or wrist cuffs have made home-based BP assessment more convenient and accessible. Howe...

BACKGROUND Asthma is common among young children. The assessment of respiratory resistance by the impulse oscillometry system (IOS), based on the superimposition of respiratory flow by short-time impulses, requires no patient active collaboration. AIM We evaluated the baseline repeatability and bronchodilator response of IOS indices in preschool children, their correlation with spirometry and...
