exhaled nitric oxide in acute asthma Central and peripheral airway / alveolar sites of

Introduction Central airway nitric oxide flux (J’awNO) and peripheral airway/alveolar nitric oxide concentration (CANO) during asthma exacerbation has not been investigated after correction for axial NO back-diffusion. Methods After measuring exhaled NO (fraction of exhaled nitric oxide (FENO); ppb) at 50, 100, 150 and 200 ml/s, J’awNO (nl/s) and CANO (ppb… CONTINUE READING
