When blood pressure is measured invasively in the operating room or intensive care unit, it is reasonable to expect useful systolic, diastolic, and mean pressure values to be displayed at all times. If blood pressure is stable from beat to beat, display of values from any beat will suffice. However, the pressure often fluctuates from beat to beat. Display of values from every beat would yield a confusing jumble of numbers. This article describes an algorithm for selecting values that appear physiological useful from blood pressure waveforms that vary with ventilation. Two classes of variation are discussed. The algorithm is optimized from the type of variation seen in pulmonary artery pressure waveforms.
当在手术室或重症监护病房进行有创血压测量时，合理的期望是始终显示有用的收缩压、舒张压和平均压值。如果血压逐搏稳定，显示任何一次搏动的值就足够了。然而，血压常常逐搏波动。显示每一次搏动的值会产生一堆令人困惑的数字。本文描述了一种从随通气变化的血压波形中选择看似具有生理意义的值的算法。讨论了两类变化。该算法是根据在肺动脉压力波形中观察到的变化类型进行优化的。
