The Effect of Spirometry on Bronchial and Alveolar Nitric Oxide in Subjects with Asthma

2013

The effect of spirometric maneuvers on exhaled nitric oxide (NO) at the constant flow rate of 50 ml/s (FE(NO)) has been studied with equivocal results. Furthermore, the effects of spirometry on bronchial NO flux (J'aw(NO)) and alveolar NO (CA(NO)), two measurements increasingly being used in clinical and research protocols, are unknown. The aim of this study was to evaluate the effect of spirometry on FE(NO), J'aw(NO), and CA(NO) in adults with asthma.Forty-four adults with asthma were studied. To assess the impact of exhaled NO measurement itself on exhaled NO values, FE(NO), J'aw(NO), and CA(NO) were obtained twice, at baseline and after a resting period of 10 min. Then spirometry (with o…
