To elucidate the relativity among three kinds of continuous hemodynamics monitoring techniques: thermodilution via Swan-Ganz catheter, pulse contour analysis method (PiCCO), partial CO(2) rebreathing method (non invasive cardiac output, NICO), in patients with mechanical ventilation.
In 13 patients with respiratory failure due to different causes, hemodynamics were continuously monitored with Swan-Ganz catheterization, PiCCO, NICO simultaneously. The therapeutic measures and the type of ventilator were similar. Data were collected at the same time points to compare the relativity among these three kinds of monitor.
Linear relative analysis showed a good relativity in PiCCO/Swan-Ganz (r=0.883), NICO/Swan-Ganz (r=0.853) and PiCCO/NICO (r=0.857) in cardiac index (CI).
PiCCO and NICO can be used as reliable measure to monitor ventilated patients bedside in intensive care unit (ICU), thus offering an assistance to optimize therapeutic strategy.
阐明机械通气患者中三种连续血流动力学监测技术之间的相关性，这三种技术分别为经 Swan-Ganz 导管的热稀释法、脉搏轮廓分析法（PiCCO）、部分 CO₂ 重呼吸法（无创心输出量监测，NICO）。
对 13 例因不同原因导致呼吸衰竭的患者，同时采用 Swan-Ganz 导管置入、PiCCO 和 NICO 连续监测血流动力学。治疗措施和呼吸机类型相似。在相同时间点收集数据，以比较这三种监测方法之间的相关性。
线性相关分析显示，心脏指数（CI）方面，PiCCO/Swan-Ganz（r = 0.883）、NICO/Swan-Ganz（r = 0.853）和 PiCCO/NICO（r = 0.857）之间具有良好的相关性。
PiCCO 和 NICO 可作为重症监护病房（ICU）中床边监测机械通气患者的可靠方法，从而有助于优化治疗策略。
