Exhaled Nitric Oxide Using End-Tidal Concentration during Methacholine Challenge
Increased nitric oxide in exhaled gas in patients with asthma is thought to reflect the severity of airway inflammation and perhaps airway reactivity. Several studies attempted to identify a relationship between exhaled NO levels and airway reactivity or severity of airway inflammation for the purpose of finding out if exhaled NO could be used in place of pulmonary function testing and airway p...
متن کاملMeasurement of Exhaled Nitric Oxide Using End Tidal Value during Normal Breathing
Increased nitric oxide (NO) production in the expired air has been associated with a number of disease conditions and may reflect the severity of inflammation in the lungs. Measurement of exhaled NO concentration has been proposed as a novel clinical tool for assessing airway inflammation and response to drug therapy. In spite of international guidelines aimed at standardizing the measurement o...
متن کاملRelationship between Methacholine Challenge Testing and exhaled nitric oxide in adult patients with suspected bronchial asthma.
Usually, hyperresponsiveness to inhaled methacholine is considered closely associated with a diagnosis of bronchial asthma. Recently, it has been clearly pointed out that bronchial hyperreactivity (BHR) is not a constant feature of asthma and that this condition is not always related to airways inflammation. In the present study we evaluated 42 Patients (21 positive and 21 negative for bronchia...
متن کاملSampling of exhaled nitric oxide in children: end-expiratory plateau, balloon and tidal breathing methods compared.
The aim of this study was to compare exhaled nitric oxide concentrations obtained during controlled slow exhalation, presently considered as the method of choice, with two sampling methods that are easily performed by children: blowing air into a balloon and tidal breathing through a mouthpiece. One hundred and one well controlled, stable allergic asthmatic children (median age 11.7 yrs) perfor...
