Assessing lung volume changes in preterm infants in car seats

Lung Volume Changes in Stable Preterm Infants Positioned in Car Seats - A Prospective Observational Study

Observational University of Zurich · NCT06724601

This study is testing how sitting in a car seat affects the lung capacity of stable preterm infants to see if it causes any breathing problems.

What this trial studies

This observational study investigates how the positioning of stable preterm infants in car seats affects their lung volume. Using electrical impedance tomography, the researchers will measure changes in end-expiratory lung volume as infants transition from a supine position to a semi-upright position in a car seat. The study aims to determine if this positioning negatively impacts lung aeration and ventilation, potentially leading to breathing difficulties. Measurements will be taken before, during, and after the transition to assess the effects of car seat positioning on lung function.

Who should consider this trial

Good fit: Ideal candidates are preterm infants born at or before 36 weeks' gestational age who are ready for discharge from the NICU.

Not a fit: Patients with severe malformations affecting lung function or those unable to understand the study procedures will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the safety and respiratory health of preterm infants during transport.

How similar studies have performed: While studies on car seat safety for preterm infants exist, this specific approach using electrical impedance tomography is novel and has not been extensively tested.
