The pulmonary artery catheter provides the opportunity to acquire indirectly important diagnostic and therapeutic information about the function of the two pumping chambers of the heart--the right and left ventricles--during the two phases of the cardiac cycle--systole and diastole. Appropriate use of hemodynamic data acquired via the pulmonary artery catheter requires the accurate measurement, analysis, and interpretation of hemodynamic pressure waveforms.
肺动脉导管提供了一个机会，可以在心动周期的两个阶段——收缩期和舒张期，间接获取有关心脏两个泵血腔室（右心室和左心室）功能的重要诊断和治疗信息。要恰当地使用通过肺动脉导管获取的血流动力学数据，需要对血流动力学压力波形进行准确的测量、分析和解读。
