- The pleurae produce an excessive amount of fluid, putting pressure on the baby's lungs, hindering breathing.
- The baby is unable to keep his or her alveoli inflated between breaths.
- The baby's cilia are damaged or destroyed, and only coughing can prevent mucus from accumulating in the lungs.
- Histamine and other inflammatory chemicals cause the baby's bronchioles to constrict.
