Pulmonary fluid balance in the human newborn infant

O Helve, O Pitkänen, C Janér, S Andersson - Neonatology, 2009 - karger.com
At birth, the infant's lungs must be cleared of fetal lung fluid. This process is mediated
through the activation of airway epithelial sodium channels (ENaC). In animals, ENaC is …
