“Dewatering” of the lungs [PDF]
Archives of Disease in Childhood - Fetal and Neonatal Edition, 1999 Editor—The letter from Hills and Masters1in response to my commentary of their paper2 raises some interesting points which require further comment. I stand corrected over my description of their model of the alveolus as “dry.” This was a short hand term on my part to distinguish Hills’ theory on which he has published widely from the more traditional ...
