A non-invasive, real time blood pressure measurement system (10) includes a cuff (40) connected to a pump (12), a cuff pressure sensor (48), and a detector (52, 54 or 56) to sense the times when the cuff (40) stops or starts blood flow in a user's body appendage. The pump (12) cyclically varies the cuff (40) pressure from above systolic to below diastolic levels at a relatively fast rate compared to the heartbeat rate enabling blood pressure measurements to be made quickly in sequence. Electrical circuitry (50) is provided to make the blood pressure measurement by correlating the cuff pressure with the detected times. This system is compatible with major types of automatic sphygmomanometric systems. |
