| Summary | This is an observational, proof-of-concept, feasibility study where 30 preterm infants on bubble CPAP with gestational age \< 32+0 weeks will be recruited from the neonatal intensive care unit (NICU) at the Montreal Children's Hospital. The study's main goals are: 1. To determine the relationship between ambient bubbling sounds and delivered pressures in preterm infants on bCPAP. 2. To determine the relationship between transmitted bubbling sounds and airway pressures transmitted to the lungs of preterm infants on bCPAP. 3. To develop models to predict delivered and transmitted bCPAP pressures from the acoustic properties of bubbling sounds. |
