1. An apparatus for continuously and non-invasively monitoring blood pressure in an animal, said apparatus comprising:

  • a device which measures impedance of the animal and from that impedance detects when a blood volume pulse is emitted from the heart of the animal;

    a sensor which detects a blood volume pulse occurring at another location in the animal;

    a timer connected to the device and to the sensor, wherein the timer measures an interval of time which elapses between when a blood volume pulse is emitted from the heart and a blood volume pulse occurring at the other location in the animal; and

    a processor which derives the blood pressure of the animal from the interval of time measured by the timer.
