Abstract
To the Editor.—
In the commentary "Bronchopulmonary Dysplasia: Twenty-five Years Later,"1 Dr Northway cited the diagnostic criteria for bronchopulmonary dysplasia. One of the criteria stated was a requirement for supplemental oxygen longer than 28 days of age to maintain a Pao2 above 500 mm Hg. Clearly, this was a misprint but it is important to realize why a Pao2 above 500 mm Hg in 21% oxygen at sea level is unachievable. The alveolar air equation is as follows:
Pao2 = (Pb - Ph2o)Fio2 - Paco2/.8
