Table 7. Time to Extubation Model

Operating room <1.0 = risk factor is related to longer time to extubation; >1.0 = risk factor is related to shorter time to extubation.

n = 3130.

CI = confidence interval; PRBC = packed red blood cells; IABP = intra-aortic balloon pump; CPB = cardiopulmonary bypass; PAC = pulmonary artery catheter; TEE = transesophageal echocardiography.
