ABSTRACT:
An automatic noninvasive blood pressure monitor with a continuous correction of the setpoint and of the gain without interruptions of the blood pressure measurement has a pressure vibration generator, the frequency of vibration being higher than that of the highest harmonic component of blood pressure wave, and a correction circuit, the input of which is connected either directly or through at least one amplifier of the basic servosystem to the sensor of the plethysmographic gauge and output of which is fed to the input of the circuit for correction of the setpoint of the basic servosystem.
