Simultaneously, inspired volumes were measured on a breath\u2010by\u2010breath basis. Inspiratory flow was calculated during both quiet and deep breathing by dividing inspired volume by excursion duration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Diaphragmatic function, studied by the measurement of excursion and thickening fraction, was preserved in all cases. However, the temporal profile of diaphragmatic excursion differed from that observed in healthy individuals. A reduction in inspiratory flow was observed and appeared to be related to the severity of obstruction, as determined by clinical presentation and flow\u2010volume loop analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Based on these preliminary findings, the combination of diaphragmatic ultrasound and inspired volume measurement should be able to provide valuable information in the assessment of upper airway stenosis.
