Implication

May guide small-volume cuff optimization in oscillometry; leaves open human validation before clinical adoption.

Key Points

  • To determine the relationship between the cuff pressure at maximum oscillation amplitude and true mean arterial pressure using theoretical modeling and experimental evaluation.
  • Formulated a one-dimensional theoretical model representing the coupled cuff-arm-artery system.
  • Conducted parallel experimental validation tests to assess how physical system properties affect cuff pressure oscillations.
  • Model analyses revealed that the cuff pressure at peak oscillation amplitude strongly depends on compression chamber air volume, arterial elasticity, and pulse pressure.
  • Experimental outcomes aligned with model predictions, showing that peak oscillation cuff pressure reliably estimates true mean arterial pressure when compression chamber air volume is minimized.

The point of maximal oscillation in cuff pressure during indirect blood pressure measurement provides a reasonable estimate of true mean arterial pressure if the compression chamber air volume is small.
