Abstract: A blood pressure monitor system with pushbutton zero-offset compensation. There is disclosed a blood pressure monitor system for monitoring blood pressure of a patient. The system includes a manual control which when operated, automatically provides a feedback signal to compensate for zero-offset of the pressure transducer when zero pressure is applied to the transducer. Zerooffset compensation is thus rapidly and easily obtained, and the signal is maintained thereafter for a long period of time. The present invention thus greatly facilitates monitoring blood pressure of a patient.
