To the Editor. —An error appeared in our article "Prediction of In-Hospital Cardiopulmonary Arrest Outcome."1
There was some confusion regarding the proper SI units for PO2 by both the copy editor and myself. The correct value for PO2 should be 60 mm Hg and not 8 mm Hg as appears in the article. The errors appear in Table 1, p 1319; Table 2, p 1320; column 1, paragraph 2, line 12, p 1320; column 1, paragraph 3, lines 9 and 10, p 1320; and column 2, paragraph 2, line 8, p 1320.
