In this episode of The Incubator Podcast, we welcome Dr. Cindy McEvoy, Professor of Pediatrics and Director of Neonatal Research at OHSU, to discuss her work on the use of extended CPAP in preterm infants. CPAP has long been a cornerstone of neonatal care, but how long should stable infants remain on support? Dr. McEvoy shares findings from two randomized controlled trials that explored whether an additional two weeks of CPAP could promote lung growth and improve longer-term outcomes.

We review the physiologic rationale behind extended CPAP, including the role of mechanical stretch in stimulating alveolar and vascular development. Dr. McEvoy explains the stability criteria used to determine eligibility for extended CPAP and how her team measured pulmonary function in neonates. Results from her studies showed significant improvements in lung volume, diffusion capacity, and expiratory flows, with early signals of reduced wheezing at one year of age.

The conversation also touches on feeding tolerance, the practicalities of implementing extended CPAP in the NICU, and the need for larger multicenter studies to confirm these findings. This episode offers an evidence-based look at how a simple extension of an existing therapy might reshape respiratory outcomes for preterm infants.
