In the Chronic Hemolytic Anemia section on page D39 (right column, 2nd paragraph), the mm Hg values was printedincorrectly. The correct sentence is below:

In the Other PH Groups section on page D40, the classification designation in the second sentence was printed incorrectly.The correct sentence is below.

In the current classification, PPHN is designated 1”.

In Table 4, the first column title should have been: PVRi, Wood unit index instead of Wood unit/m2. And the followingabbreviations should have been added: Wood unit ¼ mm Hg/l; minWood unit index ¼ mm Hg/l/min/m2.
