心血管系统成功地处理心脏手术后的病人要依靠获得并维持适当的心排量。临床多数病人心排量的估计是通过测量血压、尿量和中心与末梢温度阶差;个别情况下需要直接测量心排量。热稀释技术是现时常用的方法,而体内插入 Swan-Ganz 导管则优于以前所流行的染料稀释法。为了获得适当的心排量,应该考虑到决定每搏量
Cardiovascular Systems Patients who have successfully undergone cardiac surgery rely on obtaining and maintaining adequate cardiac output. Most clinical patients with cardiac output is estimated by measuring blood pressure, urine output and temperature center and peripheral temperature gradient; in some cases need to directly measure cardiac output. Thermodilution is the most commonly used method, and Swan-Ganz catheter insertion is superior to the previously popular dye dilution method. In order to obtain the appropriate cardiac output, should take into account the decision to stroke volume
