A vital signs monitor which includes a sensor which is applied to the main artery of a patient for detecting the heart beat and blood pressure and producing electrical pulses in waveform. A computer is connected to the sensor for receiving the waveform pulses, converting the waveform pulses into digital signals and calculating the heart rate, blood pressures and rate-pressure product. A visual display screen is connected to and controlled by the computer for displaying the heart rate, blood pressure and rate-pressure product in digital form.
