When measuring blood pressure indirectly, oscillations in the cuff pressure are observed. The cuff pressure for which these oscillations reach a maximum and its relationship to the true mean arterial pressure was investigated using a simple one-dimensional theoretical model of the cuff-arm-artery system. Results from this model indicate that the cuff pressure for maximal oscillation is strongly dependent on compression chanber air volume, pulse pressure, and arterial elasticity. Parallel experimental studies indicate general agreement with the theoretical model. The cuff pressure for maximal oscillations appears to provide a reasonable estimation of the true mean arterial pressure provided compression chamber air volume is kept small.
间接测量血压时，可观察到袖带压力的波动。利用袖带-手臂-动脉系统的简单一维理论模型，研究了这些波动达到最大值时的袖带压力及其与真实平均动脉压的关系。该模型的结果表明，最大波动时的袖带压力强烈依赖于压缩腔空气体积、脉压和动脉弹性。并行的实验研究表明与理论模型基本一致。如果压缩腔空气体积保持较小，最大波动时的袖带压力似乎能对真实平均动脉压提供合理估计。
