Respiratory Impedance and Obliterative Bronchiolitis

Summary

The aim of the present study will be to test the hypothesis that changes in within-breath total respiratory input impedance (Zrs) may provide an early evidence of obliterative bronchiolitis after allogeneic hematopoietic stem cell transplantation (HSCT). Before and after HSCT, Zrs will be measured by a modified forced oscillation technique (FOT) during spontaneous breathing both at baseline and 30 min after albuterol inhalation . Such technique may be particularly sensitive to small changes in lung mechanics observed in the early stages of peripheral airflow obstruction.
