Extract
Exhaled nitric oxide (FENO) is an inflammatory marker used in asthma management but its clinical role in chronic obstructive pulmonary disease (COPD) is less defined. FENO represents the NO production in the airways. Various mathematical models have been used to gain information regarding peripheral NO from the lung [1]. NO from the gas exchange area is referred to as alveolar NO (CANO). CANO has been shown to be increased in symptomatic asthmatic subjects [2]; whereas in COPD, there is an alveolar destruction with emphysema and higher values of CANO have been reported [3–5].
Abstract
Nitric oxide from the gas exchange area, but not from the airways, is increased in subjects with chronic obstructive pulmonary disease with low oxygen saturation after physical testing http://bit.ly/2ItUJy6
