What this trial studies

This observational study aims to utilize the forced oscillometry technique (FOT) to assess pulmonary mechanics and function in both term and premature infants diagnosed with bronchopulmonary dysplasia (BPD). The FOT is a non-invasive method that measures respiratory mechanics without requiring infants to perform specific breathing maneuvers, making it suitable for this vulnerable population. The study will employ a new device called tremoflo N-100, designed specifically for infants, to measure lung function quickly while they are sleeping. This approach seeks to provide clinically meaningful data that can enhance the understanding and management of respiratory conditions in infants.

Who should consider this trial

Good fit: Ideal candidates include premature infants with BPD who are stable on room air or low flow oxygen, as well as term infants without pulmonary disease.

Not a fit: Patients requiring invasive ventilation or those with significant congenital anomalies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic techniques for assessing lung function in infants with BPD, potentially enhancing treatment strategies.

How similar studies have performed: While the forced oscillometry technique has been successful in adults and older children, its application in infants is largely experimental, making this a novel approach.
