Bronchial or Laryngeal Obstruction Induced by Exercise?
A child suspected of exercise-induced laryngeal obstruction and asthma is examined by laryngoscopy and respiratory resistance (Rrs) after exercise challenge. Immediately at exercise cessation, the visualized adduction of the larynx in inspiration is reflected in a paroxystic increase in Rrs. While normal breathing has apparently resumed later on during recovery from exercise, the pattern of Rrs...
متن کاملAssessment of airway hyperreactivity: comparison of forced spirometry and body plethysmography for methacholine challenge tests
INTRODUCTION Bronchial challenge tests by inhalation of aerosolized methacholine (MCH) are commonly used in the clinical diagnosis of airway hyperresponsiveness (AHR). While the detection of airway narrowing relies on the patient's cooperation performing forced spirometry, body plethysmographic measurements of airway resistance are less depending on the patient's cooperation and do not alter th...
متن کاملFunctional evaluation of breath: spirometry and body plethysmography comparison in people with cystic fibrosis
[Purpose] The aim of the present study was to establish up-to-date data regarding the lung function of cystic fibrosis (CF) patients. [Subjects and Methods] Forty-eight patients of both genders, with a diagnosis of CF, were recruited. As a result our sample presented, according to the GOLD criteria, 23 patients with mild lung obstruction (FEV1%pred: 89.86), 16 patients with moderate lung obstru...
متن کاملWhen Spirometry or Whole Body Plethysmography and Lung Compliance Test Is Indicated?
Український пульмонологічний журнал. 2005, No 3 (додаток) 1.0 INTRODUCTION The detection of lung function disturbances has a great value in health and disease. We use the lung function tests in the diag nosis and monitoring procedures in different lung diseases and in general medicine. These methods are also very useful in qualifica tion of patients before thoracic surgery interventions, to det...
متن کاملPlasma catecholamines during exercise-induced bronchoconstriction in bronchial asthma.
Plasma levels of adrenaline and noradrenaline during and after submaximal exercise in patients with bronchial asthma were investigated. Three groups were studied comprising 10 patients with exercise-induced bronchoconstriction (EIB), 10 asthmatic patients without EIB and four normal control subjects. Plasma catecholamines were measured at rest, at the end of exercise, and five and 15 minutes af...
