PAC: Pulmonary artery catheter. Values represent mean ± standard deviation or %. Hemoconcentration was defined as ≥2 of 3 of delta total protein, delta albumin, or delta hematocrit in the highest quartile. No hemoconcentration was defined as ≥2 of 3 of the above variables not in the top tertile.
Represents a significant p value.
