Abstract
A method, apparatus and computer program product are disclosed for non-invasively determining blood pressure of a subject. To improve the specificity of automatic blood pressure determinations in a patient monitor provided with a non-invasive blood pressure determination unit, a physiological index indicative of sympathetic activity is derived from a subject, variations in the physiological index are monitored, and the blood pressure determination unit is instructed to initiate blood pressure determination when the variations fulfill a predetermined condition.
Claims18
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.
An apparatus for non-invasively determining blood pressure of a subject, the apparatus comprising:
- a blood pressure determination unit for non-invasively determining blood pressure of a subject;
- an index determination unit configured derive a physiological index from a subject, wherein the physiological index is indicative of sympathetic activity in the subject;
- and
- an index monitoring unit configured to monitor variations in the physiological index and to instruct the blood pressure determination unit to initiate blood pressure determination when the variations fulfill a predetermined condition.
A computer program product for non-invasively determining blood pressure of a subject, the computer program product comprising a first program product portion configured to
- monitor variations in a physiological index indicative of sympathetic activity in a subject;
- and
- generate a start command for a blood pressure determination unit when the variations fulfill a predetermined condition, thereby to initiate blood pressure determination.
