... that babies with alveolar capillary dysplasia may seem healthy at birth, but cannot breathe well and soon die? Created by Una Smith (talk). Self nom at 23:20, 30 October 2009 (UTC)[reply]

The hook is stated that way in the article; however, usually babies born with this congenital disorder of the lungs usually present with signs of hypoxemia (lack of oxygen) and severely increased pulmonary hypertension. While it is true that some may present healthy at first, it is not the norm. Calmer Waters 01:10, 5 November 2009 (UTC)[reply]

Hypoxemia? Meaning hypoxia? Babies with alveolar capillary dysplasia rapidly develop pulmonary hypertension, and they often present with this, however they do not present immediately at birth. Also, they differ from most babies with pulmonary hypertension in that therapies that usually resolve the pulmonary hypertension do not resolve it for these babies. What exactly needs to be fixed here? --Una Smith (talk) 02:20, 5 November 2009 (UTC)[reply]

Actually, I did mean Hypoxemia, as in the decreased partial pressure of oxygen in blood. Put (lack of oxygen) for other readers not in the medical field. :) I referred back to The journal of Pediatric Surgery and their review of cases from 1994 to 2002 appear to verify this fact. 25% experienced respiratory distress immediately after birth, while 75% recieved normal Apgar scores at 1 and 5 minutes. Thank you for the prompt responce. Calmer Waters 02:56, 5 November 2009 (UTC)[reply]

Thank you. Measurement of POS in newborns with "normal" deliveries is not routine, so often the first sign of trouble is cyanosis, followed by a cascade of additional signs of hypoxia and hypoxemia etc. I have edited the article to hopefully make all this clearer, but I have not found a reliable source that adequately describes this typical cascade. --Una Smith (talk) 19:53, 5 November 2009 (UTC)[reply]
