<p>This electronic blood pressure measurement device includes a cuff with pressurization, draining, and sensing means, a means for generating from the cuff pressure signal a pulse wave signal, and a means for determining for the patient a value for systolic blood pressure. This blood pressure determining means detects an interval during which the amplitude of the pulse wave signal increases substantially linearly, and sets the systolic blood pressure value using the pulse wave amplitude at the end of that interval. Optionally but desirably, this means locates an approximate start of the linear interval as being a point where the pulse wave amplitude has a certain relation to the pulse wave amplitude at the end of the interval, and determines the value for systolic blood pressure to be the cuff pressure at such an approximate start of the interval. The approximate start of the interval may be determined as the point where the pulse wave amplitude is a certain proportion of the pulse wave amplitude at the end of the interval; and this certain proportion may be approximately 60%. An operational method for this device is also disclosed.</p> |
