Changes of oxygen metabolism and hemodynamics in patients with different pulmonary hypertension undergoing cardiac valve replacement / 中华麻醉学杂志

ABSTRACT

40kPaOxygen metabolism and hemodynamics were measured with Swan-Ganz catheter techniques and reverse Fick principleResults Before anaethesia, oxygen delivery(DO_2), mixed venous oxygen pressure (PvO_2) and oxygen extraction ratio(O_2ER) in group Ⅱ were significantly lower than those in group Ⅰ (P
