Key result
In a computer-based simulation, induced errors in systolic, diastolic, and mean arterial pressures were 15, 14, and 27 mmHg, respectively, strongly influenced by pulse pressure and arterial stiffness.

May cause substantial oscillometric BP errors in stiff arteries; leaves open need for clinical validation before practice change.
Oscillometric blood pressure readings are strongly influenced by pulse pressure, arterial stiffness, and the shape of the artery-cuff pressure/volume curve, leading to potentially significant measurement errors.
Raamat et al. (2011) studied Blood pressure measurement accuracy. Pulse pressure, arterial stiffening, and artery-cuff pressure/volume curve shape was evaluated on Errors in systolic, diastolic, and mean arterial pressures. In a computer-based simulation, induced errors in systolic, diastolic, and mean arterial pressures were 15, 14, and 27 mmHg, respectively, strongly influenced by pulse pressure and arterial stiffness.
