the link between allergic rhinitis and asthma is well known. bronchial hyperreactivity (bhr) may be present in rhinitis. the present study was aimed to compare airway responses in patients  with rhinitis symptoms alone following exercise challenge, and to  determine relationship of two different respiratory function tests. 98 subjects with rhinitis were investigated by spirometry and impulse os...

BACKGROUND Determination of PC20-FEV1 during Methacholine bronchial provocation test (MCT) is considered to be impossible in preschool children, as it requires repetitive spirometry sets. The aim of this study was to assess the feasibility of determining PC20-FEV1 in preschool age children and compares the results to the wheeze detection (PCW) method. METHODS 55 preschool children (ages 2.8-6...

Background: LCI has been proven an effective tool in the detection of lung disease in CF. Objectives: a) To assess the correlation of ventilation inhomogeneity indices with structural damages of the lung, among different groups of disease severity and b) To compare the associations among MBW parameters with spirometry and CT. Method: Forty-four children and adolescents with CF participated in t...

Spirometry is the most useful and commonly available tests of pulmonary function. It is a physiological test that measures individual inhalation and exhalation volumes of air as a function of time. Pulmonologists and general-practice physicians commonly use spirometry in their offices in the assessment and management of lung disease. Spirometric indices are well validated and easily interpreted...

The link between allergic rhinitis and asthma is well known. Bronchial hyperreactivity (BHR) may be present in rhinitis. The present study was aimed to compare airway responses in patients with rhinitis symptoms alone following exercise challenge, and to determine relationship of two different respiratory function tests.98 subjects with rhinitis were investigated by spirometry and impulse oscil...

A practical method of studying the dynamics respiratory function associated with registration electrical impedance conductive biological fluids exhaled by patient is described. In model measuring cell, physical causes and relationships in conductivity air flow, saturated an electrolytic fluid aerosol created ultrasonic nebulizer have been investigated experimentally. The design a new spirometer...
