Airway distensibility with lung inflation after allogeneic haematopoietic stem-cell transplantation

► We hypothesized that airway distensibility is increased after allogeneic HSCT. ► Respiratory system conductance (Grs) was measured by FOT and lung density by CT. ► Grs showed a slight (ranging from 12 to 16%) but significant increase after HSCT. ► Airway distensibility with lung inflation increased and was correlated with lung density.
