Abstract
An automatic blood pressure measuring system employs an oscillometric method, a cuff applying pressure to an arterial vessel and then gradually reducing the pressure. On a distal side of the cuff, as seen from the heart of the subject, a pulse wave sensor presses against a distal section of the vessel. If the pulse wave sensor detects a pulse wave from the distal section of the vessel after the force applied by the cuff reaches a first target value, indicating that the initial pressure was insufficiently low, the force is increased to a second target value. After determining a relationship between the blood pressure and the magnitude of the pulse wave detected by the pulse wave sensor, blood pressure can be monitored by the pulse wave sensor.
