Measurement of exhaled nitric oxide in man.
BACKGROUND Nitric oxide is released from pulmonary endothelial cells and contributes to the low pulmonary vascular resistance. The resistance pulmonary arteries are in close anatomical proximity to membranous airways, so it is likely that some pulmonary endothelial nitric oxide will enter the airspace to allow its measurement in the exhaled breath. METHODS Exhaled air was collected from a sin...
متن کاملMeasurement of offline exhaled nitric oxide in a study of community exposure to air pollution.
As part of a large panel study in Seattle, Washington, we measured levels of exhaled nitric oxide (eNO) in children's homes and fixed-site particulate matter with aerodynamic diameters of 2.5 micro m or less (PM(2.5)) outside and inside the homes as well as personal PM(2.5) during winter and spring sessions of 2000-2001. Nineteen subjects 6-13 years of age participated; 9 of the 19 were on inha...
متن کاملMeasurement of exhaled nitric oxide in children, 2001.
Measurement of fractional exhaled nitric oxide in exhaled air is an exciting innovative technique that gives new insights in to the pathophysiology of lung disease and asthma in particular, with many potential clinical applications. Careful standardisation of measurement techniques will facilitate the use of this new measurement in paediatric respiratory medicine: this Task Force was set up for...
متن کاملThe measurement of exhaled nitric oxide in routine practice.
Exhaled nitric oxide (NO) is considered the most easily available clinical test to indirectly assess the level of eosinophilic airway inflammation in asthma, and to predict the efficacy of anti-inflammatory treatment with inhaled corticosteroids (ICS). It is possible to measure the level of exhaled NO using online or offline methods. The most widely used online method employs techniques that en...
متن کاملInfluence of atmospheric nitric oxide concentration on the measurement of nitric oxide in exhaled air.
BACKGROUND Measurement of nitric oxide (NO) in exhaled air shows promise as a non-invasive method of detecting lung inflammation. However, variable concentrations of NO are measured in environmental air. The aim of this study was to verify a possible relationship between exhaled NO and atmospheric NO values during high atmospheric NO days. METHOD Exhaled air from 78 healthy non-smokers of mea...
