How do various sphygmomanometers compare to intra-arterial blood-pressure readings in hypertensive patients?
While sphygmomanometers consistently underestimate systolic and overestimate diastolic pressure compared to intra-arterial readings, their strong correlation makes them suitable for tracking blood pressure changes.
Hunyor et al. (1978) studied this question.
