For control and CDH rodents, data were collected within the first hour of life.

A single\u2010center, retrospective review of term CDH infants from 2014 to 2020 was performed. Tidal volumes were collected every 6\u2009h for the first 48\u2009h of life or until the patient was taken off conventional ventilation.
