1. A monitor for indicating a change in a patient'"'"'s blood pressure, comprising:
- a first sensor adapted to be positioned on the patient and configured to generate a first signal representative of a physiological parameter of the patient;
a reference configured to provide a temporal reference signal;
a sphygmomanometer adapted to be attached to the patient; and
a processor coupled to said first sensor, said reference and said sphygmomanometer and configured to process said first signal and said reference signal and to generate a trigger signal indicating a change in the patient'"'"'s blood pressure when said first signal and said reference signal meet predetermined temporal criteria, and to activate said sphygmomanometer in response to said trigger signal.

Abstract
A monitor for activating a sphygmomanometer attached to a patient includes a sensor attached to the patient to generate a sensor signal representative of a physiological parameter. This sensor can be, for example, a noninvasive sensor that generates a signal responsive to blood pressure. The monitor also has a processor coupled to the sensor and to the sphygmomanometer. The processor is configured to process the sensor signal and to send a signal to activate the sphygmomanometer when the sensor signal meets predetermined criteria.

25. A method of generating a signal to indicate a change in a patient'"'"'s blood pressure, said method comprising the steps of:
-
sensing a physiological parameter of the patient via a first sensor and receiving a first signal representative of said physiological parameter; receiving a temporal reference signal; processing said first signal and said reference signal and generating a trigger signal indicating a change in the patient'"'"'s blood pressure when said first signal and said reference signal meet predetermined temporal criteria; and activating a sphygmomanometer in response to said trigger signal. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
