Patent Images
1. A method for non-invasively determining blood pressure in a patient monitor, the method comprising:
- providing a patient monitor with a non-invasive blood pressure determination unit;
deriving a physiological index from a subject, wherein the physiological index is indicative of sympathetic activity in the subject;
monitoring variations in the physiological index; and
instructing the blood pressure determination unit to initiate blood pressure determination when the variations fulfill a predetermined condition.
