Oscillometric blood pressure measurement: modeling and analysis of the area oscillogram and height oscillogram [PDF]

open access: yesFrontiers in Physiology
ObjectiveOscillometry is the most popular blood pressure (BP) measurement method. Conventionally, BP is computed from the oscillation height versus cuff pressure function (“height oscillogram”).
