Exhaled air temperature in asthmatic children: a mathematical evaluation.
Recently, the exhaled breath temperature has been proposed as a potential marker for the evaluation of airway inflammation in asthma. The purpose of this study was to verify the ability to distinguish asthmatics from normal controls by a dedicated detailed mathematical evaluation of the exhaled air curve. Analysis was performed in the different phases of the curve of exhaled temperature, i.e. t...
متن کاملinfluence of sensitization patterns on fractional exhaled nitric oxide in asthmatic children
fractional exhaled nitric oxide (feno) has been suggested as a non-invasive biomarker of airway inflammation, which is increased in atopic subjects. whether sensitization to particular allergens is a predictive factor for increased feno levels is not yet fully understood. we conducted a retrospective cross-sectional study. from october to december in 2015, the medical documents of 127 mild, ste...
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...
متن کاملNitric oxide in exhaled air.
Much interest is now being focused on measurements of nitric oxide (NO) in exhaled air. In healthy subjects exhaled NO seems to originate mainly in the nasal airways, whereas the contribution from the lower respiratory tract is low. In certain inflammatory airway disorders, the excretion of NO into the airways is altered resulting in changes in the levels of NO in exhaled air. New techniques ha...
متن کاملThe Importance of Exhaled Nitric Oxide Concentration in Asthmatic Patients and Factors that Impact its Measurement
Measurement of exhaled nitric oxide (FeNO) concentration is a simple, reproducible, and noninvasive means of identifying the extent of airway inflammation and disease control in asthma. Accuracy of FeNO measurements depends on certain host-related factors such as atopy, sex, diet, and environmental factors such as ambient conditions and measurement technique. In this study, we aimed to assess t...
